In a study with rodents and ferrets’ researchers found that using treats could mask an animal’s true intelligence. They found a difference between performance and knowledge and that there are two processes, one for
Content and one for environment. The study was conducted by Kishore Kuchibhotla, an assistant professor in The Johns Hopkins University’s department of psychological and brain sciences.
The study wanted to explore how reward-based training affects learning verses performance or behavior. Their research showed that reward-based training improved learning in steps or stages but can mask an animal’s knowledge, especially what the animal learned early in life.
The researchers hope that the results of this study and future studies will help people with Alzheimer’s Disease maintain lucidity as well as improve testing environments for children.
Reward-based training is the most humane way to train a pet, but the pet owner must recognize that the pet is more intelligent than the training demonstrates. This is evident when a pet uses the lessons he has been taught in new ways.
Because the drug has been tested in the lab and then on animal models (used in cats since 2003), researchers plan to start clinical trials in humans very soon.
Again, as I have reported a number of times, our pets have provided medical support for us. How wonderful that our beloved cats may indirectly save many lives worldwide. How hopeful it is that our scientists, including our veterinary medical professionals are a key to the cure of COVID-19. Many people do not realize how much our veterinary researchers have contributed to the overall health and well-being of people. Please read the entire article as reported by Science Daily.

Technically, chiggers are not insects – they are “arachnids” in the same family as spiders and ticks. Chiggers are also known by other names around the world: some call them berry bugs, red bugs, harvest mites, harvest bugs, harvest lice, mower’s mites, scrub-itch mites and others. Their scientific name is “trombiculidae mites” and there are approximately 30 species known to attack humans and other animals.
Where They Can Be Found
Chiggers like areas of high humidity. They live in every country around the globe except in high elevations or where it is too hot or dry. Fortunately, North American chiggers don’t seem to be carriers of major diseases unlike in East Asia and the South Pacific. In those areas’ chiggers can cause scrub typhus also known as Japanese river disease. This disease can cause fever, muscle pain, headaches, rash, gastrointestinal problems and coughing.
Chiggers live in damp areas such as grass – like fields, lawns, forests, along the edges of wooded areas, swamps, bogs, rotten logs and stumps, overgrown briar patches and other moist habitats near lakes and streams. However, although chiggers may be heavily concentrated in one spot, they can be virtually absent nearby areas.
Chiggers are most abundant when weeds, grass and other vegetation are substantial – usually in spring, summer and early fall when temperatures are in the 70s and 80s. But they avoid temperatures hotter than 99⁰F (37.2⁰C) and become inactive at temperatures below 60⁰F (15.5⁰C) and 42⁰F (5.556⁰C) will kill the biting ones.
Who and How They Attack
Only the larvae (baby chiggers) are parasitic! Nymph and adult stages do not “bite”. While adult chiggers average about 1/60 of an inch long (0.4mm) the larvae are only 1/100 to less than 1/150 of an inch (10.15 to 0.3 mm) in diameter. They are bright red, hairy, have six legs (larva pictured). Adult and nymph chiggers have eight legs. Some species of chiggers are yellow or straw-colored. After the chigger eggs hatch into larvae they don’t move very far by themselves. They congregate in groups on grass blades, low plants and bushes and small clumps of soil. They attach themselves to small mammals, birds, reptiles, rodents and humans (their least preferable host) who walk through the infested vegetation.
Larvae mites have claws that help them latch on to the host they choose – such as the shoes, clothing, fur/hair – and skin of animals. Generally, they crawl around and explore the host, sometimes for several hours, seeking a safe place before they feed. Bites can happen on any area of the body but mainly where there are folds, wrinkles or where skin in thinnest and easier to penetrate. Those areas are commonly where clothing is tight – around ankles at the sock line, around the waist, near the groin, behind knees, under the armpits – inconvenient places like panty lines, bra straps and there have been cases where they have made their way on to “private parts.” Chiggers can leave hundreds of bites on a host in just one exposure!
Other than staying out of chigger infested areas – which isn’t always possible – searchers and those working in the field should wear long-sleeved shirts, tall boots with their trousers tucked into their socks and a belt to minimize chiggers’ ability to connect directly to skin under a shirt.
Insect repellent is also suggested. But even repellents that specifically state they repel chiggers may only afford some degree of protection. Over-the-counter insect repellent effectiveness usually lasts for several hours before needing reapplication. Those containing DEET (N,N-diethyl-meta-toluamide) may be applied directly to exposed skin but avoid getting it around or in the eyes. All repellents should be used according to label directions. If sunscreen is also used it should be applied first, rubbed into the skin and let absorb before using a repellent.
Long-lasting products such as those containing permethrin should only be sprayed on clothing (not on skin) and allowed to dry on the clothes for a couple of days before wearing. Permethrin sprays on clothing will remain effective even through a couple of washings. It is important to follow all label instructions. For double protection in heavily infested areas, it has been suggested to use repellent with DEET on your skin, and permethrin treated clothing. Sulphur powder applied to clothing has also been mentioned as providing some protection. But it has a horrible smell like rotten eggs.
Author’s Note: Being the recipient of thousands of chigger bites through the years, and although trying various repellents, I have found one thing that has truly lessened them. Bounce Dryer Sheets! I have used them for years, shared them with others in the field, and they have helped! Take two fresh dryer sheets and wrap them around each ankle – that’s two sheets per ankle – under your socks. I also tuck some in my waistband and then sprayed myself with repellent. I don’t know if the “fragrance free” sheets or if any other brands work since I have only used the scented Bounce sheets.
As previously stated, the larvae, not the adults or nymphs, are what does the damage. Chiggers don’t really bite nor do they “suck blood” or burrow into the skin. The larvae have tiny, sharp mouthparts that pierce the skin – poking a hole where they inject saliva containing digestive enzymes. Those enzymes break down and liquefy skin cells causing the human immune system to respond by hardening the cells all around the hole creating a hard feeding tube structure (referred to as a “stylostome”). It is through that tube that chiggers gain access to the digested skin cells where they constantly secrete saliva to liquefy new tissue. The larvae continue to feed sucking up the fluid until they are engorged. The enzymes are what causes the intense, relentless itching that begins several hours after the initial bite.
Because of the delay between the actual puncture and the itch, the host may not at first, associate it to their exposure to chiggers. The result of these bites will be clusters or groups of red pimple-like bumps or blisters whose itching usually peaks around 24 – 48 hours after the original piercing. Chigger larvae typically feed for three days before dropping off to find a place to digest their meal and molt into their next stage of life.
After Exposure: Clothing, shoes, gear (and dog) should be thoroughly brushed off immediately upon returning from the field. Once home, that clothing should be isolated from the rest of the laundry then washed in hot, soapy water. Boots should be left outside until cleaned. Dog bedding or vehicle kennel pads should also be cleaned.
A hot shower or bath should be taken as soon as possible with repeated soaping and vigorously scrubbing with a washcloth to dislodge any larvae that remain on the body. Although some chiggers may be forced off, the itching from the enzymes in the “tube” will still exist.
Some information sites suggest a cold shower should be taken, rather than hot, to help reduce inflammation from the bites and help relieve itching.
What to Do/Human Treatment (Note: This treatment information is a compilation of ideas from reputable sources. It is not medical advice.)
First of All, Don’t Scratch. Scratching can cause a secondary infection.
Don’t put clear fingernail polish on the bites to try to “suffocate” the chiggers. The chiggers may already be gone. Remember it is the enzymes already in your skin that cause the itching.
Don’t put bleach on the bites it doesn’t work!
All itch relief remedies provide only temporary relief. The following suggestions are the most authoritative.
Unfortunately, No one remedy works equally well for most people and, even less encouraging it can take two to three weeks for chigger bites to heal!
Rubbing alcohol will burn when it touches a wound but it may have a little benefit and possibly kill any larvae if they are still attached.
Hot (or cold) showers and baths
Cold bath with a few scoops of colloidal oatmeal
Applying wrapped ice to the bites
Over-the counter anti-itch creams, ointmentsand sprays. If any contain hydrocortisone, consult with a doctor before using on children under the age of 12, or if pregnant or nursing.
Calamine or Pramoxinelotions
Menthol ointments (Vicks VapoRub)
Apple cider vinegar
Antihistamine pills such as Benadryl
Analgesics (pain relievers) may provide itch relief.
Ground up aspirin paste or baking soda paste applied to each bite.
In addition, antiseptic ointment will help prevent infection for bites that have been scraped by clothing or scratched. For severe cases of chigger bites a physician should be consulted. Steroid shots may be prescribed to alleviate the itch and if infected, antibiotics may be needed.
Chiggers on Dogs
Although a dog’s fur can protect it from some chiggers they still latch on to other areas. Those less hair-covered places such as around the dog’s eyes, ears, legs and stomach are particularly vulnerable. Once on-board they will crawl around and also climb around down into the fur looking for a good, safe place to feed.
Chiggers or Fleas
Fleas prefer warm-blooded hairy animals. They can jump eight inches high and thirteen inches horizontally. Fleas feed on blood so there may be some “flea dirt” (dried blood from bites) present on the dog’s body as can be seen in this photo. There are usually three or four bites lined up in a row in an area. They are small red bumps with a halo-like ring around them.
Chigger bites are in large, random clusters and look similar to small pimples, welts, blisters or hives.
Sometimes chiggers can be identified by observing what looks look like paprika on the dog’s fur. Those almost microscopic reddish dots are larvae.
Indications of Chiggers on Dogs
Intense itching/scratching – typically starts three to six hours after exposure – that lasts for days is the most apparent indication. While not all dogs react with itching, some may develop an allergic reaction with hives or facial swelling. As with humans, the itching enzymes will remain although the larvae will fall off after feeding for three or four days.
Clusters of Small, red crusty pimples, welts/bumps on skin which occur after several hours.
Red patches on exposed skin (can even be visible under their hair).
(If unsure of what the problem is, since other skin conditions may cause bumps, consult a veterinarian who can make the diagnosis.)
Treating Chigger Bites on Dogs
As previously mentioned, the dog should be brushed/wiped off immediately after returning from the field. It is recommended a soft cloth or vet-approved skin wipe be used around the sensitive areas. Chiggers can also infect a dog’s inner ear.
There are products/shampoos on the market to treat chigger bites on dogs but it is important to review them for safety and results. There are home-remedies (with mixture directions online) which may or may not be effective such as: bathing the dog in Epsom salts, a warm Colloidal Oat or Brewed Green Tea bath, Wrapped Ice Packs or Cold Compresses. Before using human treatments, a veterinarian should be consulted. The Vet may prescribe anti-parasitic sprays, dips, topical medication or suggest an antihistamine. In cases of severe infestation steroids may be prescribed. Remember continuous scratching can develop into bacterial infection which then would require antibiotics.
Prevention Veterinarian approved, dog medications for killing ticks and mites (Frontline, NexGard, Seresto, etc.) may help fend off chiggers. If chigger infested areas are within the dog’s home territory – Keep the dog away from them for about two weeks while those places are treated with pet-safe products.
Chiggers and the Ecosystem
After much research, due to curiosity about the “benefits” of chiggers, the most learned is that they feed on different foods at their different life stages. Larvae are parasitic while nymphs and adults feed only are various plant materials and smaller arthropods in the soil. Natural predators of chiggers (and other mites) are spiders, beetles, birds, lizards, centipedes, salamanders, certain species of ants and other small creatures which live in areas populated by chiggers.
Note from Susan: While this article applies to people and dogs, chiggers can bite cats and other animals as well.
A study by scientists at theUniversity of Notre Dame on baboons has shown that early adverse conditions such as famine, abuse, neglect or the death of a parent in early childhood are not reversed by support in adulthood. They feel that things such as elevated stress hormones take a physiological toll on the body, and remain, even with a healthy, supportive relationships in adulthood.
Because the subjects of the study were baboons, scientists measured life experience against levels of glucocorticoids (fGCs) — hormones that regulate physiological functions such as metabolism and immune function, and moderate the body’s response to stress. They found that the levels of fGC’s were 9% higher in subjects that had three or more adverse experiences and 21% higher than subjects that had no harsh experiences.
I have to wonder how this study relates to other animals. Does this mean that pets who are abused or experience harsh situations as youths, will not ever fully respond to kind treatment when they are adults? Will the stress always be with them? What comes to mind are children who are given up for adoption at birth and then suffer from attachment disorder. While further research is needed and on a wider subject base (other animals) this is important information to keep in mind when trying to rehabilitate abused pets. This may mean that failure is not the result of poor rehabilitation techniques, but is a result of the chemical changes in the subject.
This is an interesting study and one that everyone should read. According to the study conducted by Gary Whittaker, professor of virology, is the senior author on the study at Cornell University, primates, cats, ferrets, and mink are the most susceptible to the human virus.
According to Whittaker, further research into feline coronaviruses might provide further clues into SARS-CoV-2 and coronaviruses in general.
It has been fully documented that children who suffer from autism can benefit from living with a pet. However, a new study by Gretchen Carlisle, a research scientist with the Research Center for Human-Animal Interaction in the MU College of Veterinary Medicine has found that the parents of autistic children also benefit from having a pet in the family. Having a pet reduces the stress in parents despite the extra responsibility of owning and caring for a pet.
The study goes on to stress that the right type of pet should be selected that will help the autistic child. They suggest that in some cases a quieter cat may be better than an active dog. Certain types of birds or small animals might also qualify as a pet. They also suggest that the child be included in the selection of the type of pet.
As a certified animal behavior consultant, I want to add that if the family decides to adopt a pet, extra care must be taken to ensure that there are no behavioral issues with the pet that could cause an extra level of responsibility for the parents. For any child, being forced to rehome a pet due to behavioral issues after the child becomes attached to the pet is not a desirable situation.
This is why it is important to thoroughly research the types of pets as well as the individual animal to make sure it is suitable for the spectrum of autism the child has. One way to do this is to consult with a qualified dog, parrot or cat behavior consultant (iaabc.org) or an experienced dog trainer if a dog is a consideration.
They most certainly do! Daiana de Souza Machado, from the Universidade Federal de Juiz de Fora, Brazil, and colleagues has conducted a survey to explore whether cats suffer from separation anxiety when left alone. Although this study needs further investigation, I can personally attest to the fact that more than one cat that I have owned has shown displeasure at being left alone for a weekend.
Many people think that cats are fine being left alone for a few days while their owners go away. I have been guilty of leaving my cat alone while I went on an overnight trip. If the cat does not have a companion, such as another cat, they do miss their owners. In my case, although two cats that I owned did not like being left alone, they were not destructive. However, they were excited when I returned and vocalized their feelings. They made it clear that they were not happy being left behind.
In the survey that the researchers did, the cats that were left alone showed a variety of behaviors including excess vocalization and some destructive behavior.
Cats are much more social than many people realize. There are some cats that may not like to be cuddled and handled as much as others, but they still enjoy being near their owners and having the companionship.
Because cats sleep 12 – 16 hours a day, they may give the impression that they are not social since they are not as active as dogs. However, the hours that they are awake they crave companionship. And like many people, they sleep better knowing that their owners are home or that it is the normal routine.
So what is a solution if you must leave a cat overnight? If you know that this is going to be a common occurrence, you can own two cats instead of one. They will be company for each other. Another option is to have someone the cat knows and trusts visit the cat often or stay at your home while you are away.
Part of the problem is that cats do not like change in their lives. They are fine with the daily routine of their owners being gone for the day while at work, often sleeping the day away. Cats, just like dogs have an acute sense of time and recognize that on the weekends their owners are home most of the time. So when the owner goes away overnight, the cat will recognize that this is not the normal routine.
While more research needs to be done about separation anxiety in cats, it is important for cat owners to realize that their cats do love and miss them while they are away. Owners should take this into consideration when planning a weekend away or a vacation.
A friend of mine who is not a dog trainer or behaviorist, suggested to me that dogs may suffer from stress due to the current pandemic. That was very insightful of him. The more I thought about it the more likely it seemed. Therefore I am addressing this possibility.
Anytime your routine changes and your pet, (mostly dogs and cats) notice the change, it can stress them. In the case of being home bound, as opposed to going on vacation or visiting, you are more likely to spend more quality time with your pet. This may mean more play time, more cuddle time, and more people at home collectively giving the pet attention. The pet will enjoy this and most likely be happy. However, some dogs and cats do not like the extra attention, especially from children, because they can suffer from over-stimulation. In some cases the pet will give subtle warnings asking to be left alone, but many people will not recognize them. The result may be a bite or a scratch. It is especially important to watch older pets who may not be physically able to handle the extra attention. If your pet does not seem willing to engage with you, leave him alone.
Family members may use the extra home time to groom their pets more frequently. In the case of older pets it is important to be aware that if they suffer from arthritis or a sore muscle from the extra exercise, brushing may be anywhere from uncomfortable to painful.
If the pet is younger and getting more exercise, watch their weight because they may need to eat a little bit more food since they are burning more calories. This is especially true for younger and physically fit older dogs.
We know that our pets feel and understand our emotions. As the pandemic continues, some members in the family may become more upset and stressful, your pet may react to this. They may cling to you or follow you around whereas they did not before. They may mope, or even avoid being as near to you as they normally were. They may pant more frequently, pace, or even tremble as their stress level rises along with yours. They may also react if the family members become short tempered or there is discord in the family. This is especially true if there are children in the home and they become irritated because they cannot see their friends or go out to play. Some pets are more protective of children and may react to their stress more than they would to an adult. A great activity for children is to read to the pet. It is calming for everyone.
Don’t forget that your pet does not understand the change in the family dynamics. They only understand what they see and experience. Therefore, it is equally important to watch how your pet reacts when you return to work or your normal schedule. At this time your pet may react to the sudden shift from having companionship 24/7 to being alone.
Rest assured that your pet will not forget what normal life was like, they do have the ability to recall the past, but again, they will not understand the change. More importantly, they may not like the change. It was certainly more fun having the family around all the time. To ease the shift back to normal, try to give your pet as much attention as you can when you first return to your regular routine. Gradually ease back to the normal routine that you had with your pet.
Fortunately our pets are very adaptable so many will not show any signs of stress due to the changes in our daily lives. But it certainly helps to keep a careful eye on your pet and to be aware that they know something is going on. Because they love us and care, they may react as they feel is necessary. Most important of all, show them understanding if they react in a way that becomes annoying to you.
Other circumstances that cause stress for a pet are:
Moving to a new home
Adding a new family member
Losing a family member
Changing the normal routine
Working more or less hours
Adding a new pet
Losing a pet in a multiple pet household
If your pet becomes too difficult to handle, feel free to contact a certified behavior consultant at www.iaabc.org Many of us can offer phone consults.
I was contacted by Scruffy Paws Nutrition for Cats to see if I would test and review their products. After reading about the company and their philosophy as well as their attention to specific health issues for cats, I was impressed, and as my regular readers know, I am very critical.
I was offered the opportunity to try a product of my choice on my cat. Unfortunately my cat would not eat the vitamins, she is very fussy. You don’t want to know how many brands of wet food I tried to find one that she would eat along with her Annamaet dry food.
Here is a quote from their site: “Each supplement has been specifically designed for a certain ailment. So instead of a ‘Jack of all trades’ vitamin supplement that may not do any real good… Ours laser target feline conditions to make a real difference. Using our wealth of knowledge and experience, we formulate a nutritional top up that will supercharge the organ health, and help the body heal itself.”
However, I feel that I should share these products with my followers and hopefully you will check them on the Scruffy Paws web site.
In a recent study at North Carolina State University a human adolescent who suffered from a rapid onset of schizophrenia symptoms was found to be suffering from a Bartonella henselae infection which is associated with cat scratch fever.
This person was treated by an array of doctors for 18 months before one doctor noticed lesions that are associated with Bartonella. When tested it was found that Bartonella was the cause of the schizophrenia like symptoms.
This is an important discovery since now researchers are going to investigate other psychiatric disorders and their connection to viruses and bacteria infections. This could lead to cures for afflictions such as Alzheimer’s disease and other medically complicated issues.
Cats that have Bartonella can infect a person from scratching, biting or even licking a person. Strictly indoor cats are less likely to have it. The symptoms typically are flu-like which include:
a bump or blister at the bite or scratch site.
swollen lymph nodes near the bite or scratch site.
a low-grade fever, which is above 98.6°F (37°C) but below 100.4°F (37°C)
