A little hair shedding is quite common in all the furballs. Our furry mates generally lose some hair while playing and walking around. But if your kitty is losing hair to the extent of exposing bald spots, then it’s a matter of concern.

Moreover, hair loss is accompanied by symptoms like itching, sores, scratches, and redness to mention a few. Whereas, in some cases, your feline might simply face a hair loss problem.

Why Do Cats Lose Hair

Reasons Why Your Cat Is Losing Her Hair!

There can be various reasons why your cat is suffering from hair loss. Skin allergies, ringworms, fungal infections, mange, and alopecia are few of the medical conditions that cause hair loss in cats. Another issue could be overgrooming where a cat starts licking off her own furs because of stress.

Our recent review: We tested 35+ products and found the best cat brushes for your furry friend to look and feel good.

It is essential for you to find out a correct cause to why your cat is losing her hair. A vet will examine your cat thoroughly to determine the problem and provide you an appropriate hair loss treatment. Let us see what could be the possible reason and the symptoms associated with a cat losing hairs.

1. Skin Allergies Can Cause Fur Loss

A cat shedding fur could be because of allergies caused by fleas and ticks. She will excessively lick her fur as it makes her skin irritated and to soothe her pain she will naturally lick fur.

This happens because the saliva of a flea includes antigens that cause itchiness. So, the process of soothing can lead to hollow patches in her fur because even if hair grew she will again nibble it to satisfy her itching.

Skin Allergies Can Cause Fur Loss

Sometimes it can also happen due to the rise of mites, lice, or food allergies.

2. Presence of Parasites

If you discover the presence of parasites like ringworm in your cat’s tummy it can also lead to cat alopecia. This is not normal or common because parasites lead to fungal infections or yeast infections.

Presence of Parasites

The infection will cause hair loss in the infected area. And, if not then the feline may lick the wounds excessively causing patches and loss of hair in that area.

3. Imbalance of Hormones

If your cat’s hormones are imbalanced it can also cause hair loss because certain hormones are made for hair growth which can increase or decrease the growth of hair. Hair follicles depend on hormones to work and if it is not balanced it can cause bald patches.

Imbalance of Hormones

For instance, if your cat is pregnant, or she is lactating her body undergoes several hormonal changes due to which she can lose her hair a lot. But, this should stop once she has weaned her kittens.

4. Your Cat Is in Pain

Not necessarily your cat will lick her excessively when she is affected by infection or allergy she can also lose while excessively grooming herself when she is under painful conditions.

Your Cat Is in Pain

If her body aches she will lick to control her discomfort. This especially happens in the case of arthritis the pain in her joints and bones will make her uncomfortable and to reduce her pain she will start licking her joint pain.

5. Stress Leads to Hair Loss

Stress levels can increase hair loss. Wondering, how?

Stress Lead to Hair Loss

Well, a stressed cat will try to relieve her tension by licking and scratching. For instance, if you have recently shifted to a new home you will see signs and symptoms in your cats like excessive licking, and intense scratching claws and this leads to hair loss.

6. Poor Diet

Cats are carnivorous animals they solely depend on meats for their body growth and if their diet is full of grain and less of the right nutrition it can cause underlying health issues amongst which hair loss is one of the diseases.

Poor Diet

Sometimes if she gets allergic to the food she may suffer from alopecia too.

7. After Effect of Medicines

Certain medicines can have many side effects and cause alopecia in cats. If she is using Transdermal prednisone make sure to stop it right now as it can be the leading reason for hair loss in cats.

Plus if she is taking medicine for chronic illness take a note and speak to a good vet before giving it to your cat.

And, an overactive thyroid (Endocrine Disorders) can also cause hormonal imbalance and can increase steroids in the body which can cause hair fall.[1]

11. Ringworms

Ringworm is a type of fungal infection that affects skin, hairs or nails. The infection looks like a red bumpy ring, that causes inflammation and itching. However, the infected areas are not always in a round shape.

  1. Sneezing or wheezing
  2. Itching and scratching
  3. Coughing in cats with asthma
  4. Itchy ears or eyes
  5. Diarrhea or vomiting
  6. Swelling in paws

A veterinarian will suggest you eliminating certain foods in your cat’s diet. The vet will give alternate food options and required medicines to treat the condition.

13. Painful disease

If your cat has a painful disease like arthritis then she will lick frequently onto the joints. This condition is more often noticed in older cats. Symptoms of Pain in cats mostly include

  1. Lethargy
  2. Hiding and sitting still
  3. Agitation or boredom
  4. Over-grooming certain spots
  5. Purring
  6. Immoderate meowing
  7. Not using the litterbox due to pain

Problems like arthritis do not have a permanent solution, though, a veterinarian can provide you with pain relievers to soothe the cat.

14. Psychogenic Alopecia

Psychogenic Alopecia is a psychological problem where cats over lick themselves due to stress. It happens when a cat cannot overcome trauma leading to compulsive over-grooming. Symptoms of Psychogenic Alopecia are

  1. Licking off fur by continuous over-grooming
  2. Bald patches mostly on the abdomen
