Cats naturally shed their hair at the beginning of each season to gradually recover it. But it happens that the hair loss is abnormal and sometimes even reveals bits of skin.

If you have a cat that is losing its hair to this extent, it is vital to know the cause and implement the appropriate solutions. So, stay tuned with me, I am taking you step by step in this article to fix the problem.

Cat losing its hair: The causes and their different solutions

Each cat loses its hair because its lifespan is limited, like our hair. But several causes can be the source of abnormal hair loss in the home, so here are the most common causes and their solutions. You will also know how to recognize them to act correctly.

An allergy

The cat can be allergic to several things, here are the main allergenic substances for cats, which are similar to ours. It is not directly the allergy that causes the hairs of the cat to fall out, but they can itch and the cat then begins to scratch to get over these genes, it then loses its hair in large quantities.

To food

Cats can have allergies, especially those related to food, which can cause excessive hair loss. If your cat loses hair after you introduce a new food source, an allergy is likely. Remove this new food and go to the veterinarian to determine the exact cause of the allergy and so that he can guide you to a new source of food that will be healthy for him.

Some cats also develop an allergy at some point in their life, without their diet having been changed, and in this case, make sure that your cat can go to the veterinarian if no other cause seems credible to you.


Your cat may also be allergic to pollen, if it is pollen season and he has eye problems or a runny nose when he is outside, check the pollen calendar and make sure he can keep his nose free and put some cat saline on him so he can get better. There are many solutions for this allergy.

Overall, you’ll need to get him treated but can keep his symptoms under control by making sure he can stay indoors when it’s really hot and windy, which is a contributing factor, but also that he can have an air with less pollen inside, for example by giving him an air purifier.

To mites

If your cat is sick after falling asleep or lounging in bedding, then he’s probably allergic to dust mites, and you’ll need to get him a hypoallergenic bed, although a trip to the vet is highly recommended.

The stress

Stress and cat do not mix, because if in the wild it is a precious defense tool, allowing the cat to react quickly to threats, it is completely useless in your home, and stress can lead to a excessive licking or scratching, causing this annoying hair loss.

Stress can be due to changes, such as the introduction of an animal, to which it will have to be accustomed gradually. Cats have an adaptation period of about 1 month. You can give him soothing pheromones to calm him down if he’s under stress.

It can also be due to an environment that is too noisy or that regularly surprises him. Your cat needs calm, so let him have this vital need. Everything related to his personal space must be put in a calm place away from stress, because he must feel completely safe there.

Finally, stress can be due to boredom, if your cat feels too lonely, a second cat might be a good idea. And at least give him games that will allow him to occupy himself and exercise, especially if he is still very young, such as an electric fish or a cat wheel.

The stress can even lead to excessive licking and scratching which will make her hair loss worse, with the skin possibly even becoming bloody.

You can recognize a stressed cat by its behavior, very agitated or very fearful, and you will have to accustom it or remove the dangerous element so that it can regain its calm. In the meantime, you can diffuse a soothing spray that will act on his pheromones to calm him down quickly.


Parasites are a horror for cats, especially outdoor cats who often catch them in high foliage in the spring and fall. These will then integrate the body of the cat and multiply there, until killing it.

If your cat scratches often or you find parasites in their stool or hair, then the parasites are likely to be the cause, causing them to scratch.

It will therefore be necessary to obtain treatment from your veterinarian as soon as possible in addition to having it dewormed to protect it afterwards, in the meantime, an anti-parasite cat shampoo can help it relieve discomfort and avoid scratching.

Hormonal disorders

Hormonal hair loss occurs in sterilized male cats who will often scratch and hair loss will be visible on the genitals. A hormonal disorder should lead to the vet.

Diseases and infections

Certain fungal diseases can create circular hair loss. If lotion or shampoo doesn’t help, call the vet to give you what you need.

A wound

If your cat is scratching in a specific place, maybe it’s a wound, then you will see a sore. In this case, it is vital to disinfect it at the level of the wound with an antiseptic and to cover everything with a clean bandage, without tightening it too much. Cut the hair around if necessary.

Your cat won’t like it and yet it will help him heal and prevent aggravation from scratching. If nothing helps, the veterinarian is also the only solution for your cat.

The medication

Some medications have side effects that can cause feline hair loss. So if the fall started while your cat was taking a new medication, have it changed by going to the veterinarian.

If the problem is mild, keep an eye on it, but do not hesitate to go to the veterinarian if the problem worsens.

Not enough nutrients

If your cat does not have enough diversified food to provide it with all the nutrients it needs, then it is vital to feed it well with at least cat food and nutritious kibble.

You can also give him omega 3 and 6 so that his immune system is strengthened and he is less prone to diseases and allergies.

If he eats a lot and yet has a dull coat suggesting malnutrition, it is because parasites are absorbing all these nutrients.

Special cases

There are many special cases concerning this problem, here are the most frequent of them.

Cat losing hair and losing weight

By far the most likely cause is the presence of parasites such as ticks and cats which will require prompt treatment and deworming to prevent this from happening again. The parasites are not insignificant and cause the cat to lose weight by multiplying and absorbing the nutrients of the cat, which without treatment will die.
