Until now, no one has seriously studied a cat’s ability to detect odors. A collection of researchers found that when a cat takes in air, their nose divides it into two flow streams. One flow stream is cleansed and humidified which goes to the lungs and the other is sent quickly to the olfactory region. What the researchers found is that a cat’s nose is a highly efficient dual-purposed gas chromatograph. This makes the cat’s ability to detect odors equal with that of a dog.

The odor detection part of the cat’s nose acts very quickly so that the cat can determine what is food, foe or friend. The researchers feel that the discovery about how a cat can detect odors may inspire improvements to the gas chromatographs that are used today.
