Hair Loss in Cats

7-22 _ hairloss _BlogTh.png

Does your cat seem to be going bald? And what, if anything, can you do about it? There are, in fact, lots of reasons why a cat can be bald or suffer from hair loss or alopecia.

Sometimes cats are born bald

Some cats, like the Sphynx, are born with hardly any hair. In these cats, the lack of hair is a genetically determined and desirable characteristic among proponents of the breed. Some folks seek out this particular look in a cat just like others might prefer a long-haired cat over a short-haired cat.

Sometimes feline hair loss is benign and temporary

There are also passing reasons for hair loss. Just like people go through stages where they lose more hair, cats can too. Shedding is a natural and normal process that can vary in degrees. Cats that are sick or stressed for other reasons (illness, fevers, respiratory infections, pregnancy, etc.) can shed excessively. These are not conditions that demand treatment since the cat’s coat should return to normal over time.

Sometimes the hair loss is medically important

It is important, however, to consult your veterinarian if you are noticing any changes in your cat’s coat or if they are developing bald areas. Sometimes hair loss is due to a medical problem that does require intervention since the underlying reason for it can cause more serious and systemic problems relating to your cat’s overall health.

Your veterinarian will want to determine if your cat’s hair is falling out on its own or if they are scratching, licking, or chewing the hair off as a result of some inflammation or irritation. This distinction can help to focus the diagnostic approach in your cat’s case. Generally, if your cat is actively causing the hair loss, you and your veterinarian will be looking more for causes of dermatitis or inflammation of the skin (like allergies) or for infectious diseases like bacterial, fungal, or parasitic diseases (like acne/pyoderma, ringworm or mange mites). In these cases, the answer may be found through skin scrapings, cytology, cultures, or allergy testing; and appropriate therapy can result in hair re-growth.

In dogs, hormonal imbalance (underactive thyroid, adrenal dysfunctions, etc.) is a common cause of poor coats and hair loss, but these conditions are not as common in cats. Overactive thyroid (hyperthyroidism), however, does occur frequently in older cats and can cause coat changes as can almost any other systemic or metabolic disease; your veterinarian may want to do diagnostic tests to know for sure.

Sometimes the hair loss is psychological

That is not to say that it’s “all in their head” and that your cat isn’t really going bald. Rather, it means that many cats become obsessive about grooming. Obviously, grooming is a major focus of your cat’s average day, but cats exhibiting psychogenic alopecia can break off their hair right down at the skin and over large areas of their bodies – sometimes any and every place they can effectively reach leaving hair only on their head and neck.

The compulsion may start because of some irritation to the skin (as above), and then potentially continue on habitually, even after the inciting problem has resolved. Other cats will groom excessively for solely emotional reasons – a change in environment, a new family member, or some other stress. Whatever the reason, this form of alopecia indicates that your cat is either physically or emotionally uncomfortable or unhappy, and every effort should be made to determine what the problem is and to correct it either with medical or behavioral therapy.

In summary, hair loss or alopecia in cats can be just a cosmetic issue or it can be due to a primary skin problem. It can also be an external indication of a more serious systemic or psychological disorder. Consult your veterinarian as soon as you see any changes in your cat’s coat so the two of you can address the problem as soon as possible.

If you have any questions or concerns, you should always visit or call your veterinarian -- they are your best resource to ensure the health and well-being of your pets.

Excessive Shedding and How to Stop or Minimize It

Dogs naturally lose old or damaged hair by shedding. Although shedding is a normal process for dogs, the amount and frequency of hair that is shed often depends upon their health and breed type. It can also depend on the season-many dogs develop thick coats in the winter that are then shed in the spring. Dogs who are always kept indoors, however, are prone to smaller fluctuations in coat thickness and tend to shed fairly evenly all year.

How Can I Minimize My Dog's Shedding?

While you cannot stop a healthy dog from normal shedding, you can reduce the amount of hair in your home by brushing your dog regularly. Your veterinarian or groomer should be able to recommend a specific type of brush or comb that will work best for your dog’s hair type.


What Would Make a Dog Shed Excessively?

What seems like excessive shedding can be normal for some dogs, but it can also be the result of stress, poor nutrition, or a medical problem. Your veterinarian can best determine if your dog’s hair loss is part of the normal shedding process or is a symptom of an underlying disorder. Excessive shedding can sometimes be prevented through proper nutrition. Quality pet-food manufacturers work hard to include the right amount of nutrients so that supplements are not needed, but dogs with allergies and/or sensitivities still might need to experiment with different brands and formulations to discover which food works best for them. We recommend that you consult your veterinarian for advice on what foods will best suit your dog.

Excessive hair loss or bald patches may be due to one of the following:

  • Parasites (fleas, lice or mites)

  • Fungal or bacterial infections

  • Inhalant or food-related allergies

  • Kidney, liver, thyroid or adrenal disease (including Cushing’s)

  • Pregnancy or lactation

  • Certain medications

  • Self-induced trauma due to licking

  • Cancer

  • Immune disease

  • Sunburn

  • Contact with irritating or caustic substances

When Is it Time to See the Vet?

If you notice any of the following conditions, or if your dog’s initial skin problem persists for more than a week, consult with your veterinarian for treatment.

  • Skin irritation, including redness, bumps, rashes or scabs

  • Open sores of any kind

  • Bald spots or thinning of coat

  • Dull, dry hair that pulls out easily

  • Scratching

  • Constant foot licking or face rubbing
