What are the causes and how to treat hair loss in your cat

When you've fallen for your cat, his coat may not have been foreign. A soft fur, shiny, sometimes silky, delicate, smooth ... It is therefore perfectly normal that you worry if your cat begins to lose his hair. It does not matter in some cases. In others, however, there are a few things that need to be done. We explain to you the different possible causes of these losses never pleasant.

Several indicators of your cat's health are directly visible on him. Of course, his behavior , his appetite , but also and especially his coat. A fur that retains its original vigor, solid, clean and silky (depending on cat breeds) will reassure you about the general condition of your pet. Conversely, dull hairs or hairs that fall en masse will alert you. Even if it can be a quite classic phenomenon, as during periods of moult.

The molting of the cat

The alopecia areata is considered normal in moulting . Your cat will see a renewal of his dermis in the spring and fall. Of course, not all races mutate. This will be particularly the case of races with long hairs . The losses can sometimes be abundant. However, you will never notice holes on the surface of your skin. In addition, it often happens that a cat that gave birth to kittens loses some hair. You do not have to worry.


Many parasites can be responsible for hair loss that is often localized . This is for example the case of scabies and ear mange . Each time, the origin comes from mites. Your cat will usually scratch his head and ears . The itching is intense. Your cat will scratch to the point of seeing lesions and crusts form . The hairs will fall . We find this disease quite often in the kitten.


It is a classic and contagious disease of the cat's skin and is transmitted to men and its congeners . The ringworm is actually a fungus responsible for skin lesions often important . We can even talk about mycosis . The loss of hair is general , even if your cat will present more areas depilated on the head and in the back . Note that, unlike scabies, your cat does not scratch excessively and suffers no pruritus.


The loss of hair in your cat can be caused by allergies including food allergies . In these cases, the allergy is manifested by depilated areas , red patches visible on the whole body as well as itching . Attempt, from the beginning, not to give a low-end food to your pet. Indeed, allergies often result from this poor and deficient diet . In addition, for sensitive cats , you can buy hypoallergenic food .

Note that there is also a loss of hair following dermatitis by allergy to flea bites. In this case, your cat will lick, or bite, sometimes to the blood to relieve himself.

A behavioral disorder

Hair loss, often general, can be caused by a behavioral disorder in your cat. Especially if he is more stressed , anxious or worried . A hypersensitive cat will tend to renew these periods of hair loss. He will lick excessively the side as well as the belly . A bit like when humans bite their nails . In fact, hairs will tear from these areas, causing irritation and the appearance of red patches.

Hormonal diseases

They are much rarer, but in case of hormonal imbalances , your cat will experience skin disorders with a loss of hair in the back and side, sometimes with a change in coat color.

The solutions

The solution depends on the cause. Faced with scabies or ringworm , then you will need to apply lotions and creams prescribed by your veterinarian. More generally, medicated baths are encouraged, in addition to washing all of your cat's litter, toys and bedding. In short, a real spring cleaning.

In the case of an allergic reaction , we suggest you change your diet and move to a more upscale food .

In case of loss of hair from too much stress or behavioral problems , try to calm your cat, comfort him , reassure him and find anything that can bring him back to no longer lick.

In summary

There can be many causes of characteristic hair loss , apart from the traditional moulting periods in spring and fall. The origins can be unhealthy, parasitic, hormonal, allergic or related to the behavior of your cat. Identify each time the cause to deal with the consequences, thanks to the help of your veterinarian that should never hesitate to consult.
