Home Remedies for Cats With Hair Loss

Unless you have a hairless breed, your cat shouldn't look like this. See more cat pictures.

When you're a cat owner, you're used to dealing with cat hair -- using a lint roller to get it off your dark clothes, vacuuming it off of your sofa, even picking it out of your food on occasion. Unless you have a hairless breed such as a Sphynx, there's a certain amount of natural hair loss that you should expect. However, if your cat's hair is visibly thinning, there are bald patches, or you notice areas that are inflamed and red, there's a problem. When your cat loses more hair than normal, the condition is called alopecia.

There are lots of different things that can cause hair loss in your cat, including parasites, diet, psychological factors, infection, allergies or something more serious. Your cat may scratch and groom excessively with an infestation of fleas or mites as well as a fungus like ringworm, causing hair loss. Hair loss can be self-inflicted as a result of stress. A less-than-adequate diet or a change in diet can cause hair loss. Alopecia can also be a manifestation of another condition or disease, requiring diagnosis by your vet.


If there is hair loss in places where you see your cat nibbling regularly, such as his leg or paw, the alopecia is probably a reaction to a parasite. Giving your cat a thorough once-over should turn up the source of the problem, and your vet can suggest medications to get rid of the parasite. When your cat is no longer licking and scratching the area, the hair should grow back with time. It's especially important to get treatment if you suspect a fungal infection, as these can easily spread to humans (in addition to your other furry friends).

But what if you can't find any parasites on your cat to go along with the hair loss? Or there are other symptoms? Next, we'll look at other potential causes of alopecia in cats, and how they can be treated.


What else might be causing your cat to lose his hair? It could be a food allergy. If you've changed your cat's food lately, simply changing it back could get rid of the problem. Cats can also develop food allergies over time, so you may need to try different foods.

Does your cat have a "hot spot"? Also known as acute moist dermatitis, this condition is more common in dogs, but cats can get it, too. Hot spots start with a skin irritation, such as a flea or tick bite. When your cat grooms the area, bacteria can infect the wound. These oozing sores are hot, painful, and can spread quickly. Your cat makes the problem worse by licking the area, keeping it wet and preventing it from healing. After diagnosing and treating the underlying cause (if there is one), the hot spot needs to be treated. Your veterinarian may shave around the area to promote drying and prescribe antibiotics.

Hair loss can also be self-inflicted due to psychological factors like stress; upset cats will sometimes groom excessively to soothe themselves. When you see your cat doing this, you can try to redirect the behavior by giving him more attention (or, ideally, removing the source of stress, although that's not always possible). Your cat may also benefit from anti-anxiety medication; consult with your vet if the problem becomes severe.

If the alopecia is in a hard-to-reach place (between the shoulder blades, for example), it's probably not self-inflicted. 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. If your cat's hair loss is accompanied by changes in appetite, vomiting, weight loss or fever, get him to the vet immediately.
