catIn our recent conversations on the blog, you may have seen references to whisker fatigue. Today, let’s take a moment to explore and unpack what whisker fatigue really is.

Why are a cat’s whiskers important?

While many mammals have whiskers (also known as tactile hairs or vibrissae), cats’ whiskers are highly specialized sense organs. At the base of each whisker, a proprioceptor is can detect the slightest movements in air currents to help a cat catch prey. Proprioceptors also help cats determine if they can squeeze through tiny passageways. They even help cats judge shorter distances that they cannot see well because of their farsighted eyes and the blind spot beneath their muzzles.

What causes whisker fatigue?

Whisker fatigue occurs when the proprioceptors are over stimulated, usually due to constantly brushing against the sides of a water dish or food bowl. Think of it like a barrage of sensory information, much like watching a movie with too many loud noises and excessively vibrant colors. Some vets, such as Dr. Neil Marrinan of the Old Lyme Veterinary Hospital in Connecticut, prefer to think of it as more of whisker “stress” than “fatigue.”

What are the symptoms?

A cat experiencing whisker fatigue may pace around the bowl, remove all of the food before eating it, or refuse to eat at all even if they appear to be hungry. In an article with PetMD, Dr. Marrinan also warns that these could be the symptoms of serious tumors or gastrointestinal problems. When in doubt, you’ll rarely regret taking your cat to the vet!

How can whisker fatigue be prevented?

The simplest solution is to replace your cat’s food dish with a flat, wide plate without a lip on the rim. You should also change out your cat’s standing water bowl for a fountain or another free flowing water source with a wide basin. Most importantly, you should never trim your cat’s whiskers because it would negatively impact your cat’s balance and perception.
