Compulsive hair-pulling is called psychogenic alopecia, which essentially means your cat is yanking out his hair by the mouthful because something is bothering him psychologically. This could include life changes such as moving to new quarters or gaining a new family member or pet, or other changes in his routine.reatment. Don't assume your kitty has a mental problem just because you see bald patches. Visit your vet and have her run tests to rule out other, easily corrected medical issues. If nothing medical is causing your kitty's urge to yank, try to identify when the problem started to narrow down the origin of his stress.
One possibility is contact dermatitis -- an allergic reaction from something your cat has rubbed against. If the hair loss is limited to the lower legs, for example, it could be a reaction to a new rug. You may have to do some detective work to figure out the cause, but once you remove it, the hair should grow back. Your vet may prescribe a hydrocortisone spray to stop the cat from scratching. Alopecia can also signal a more serious problem, such as a hormone imbalance. Cats with either hypo- or hyperthyroidism (an under- or over-active thyroid) may experience patchy hair loss, and an excess of the hormone cortisol can cause thinning hair in a symmetrical pattern on your cat's trunk. These conditions must be diagnosed with a blood test.
