I've just discovered that my cat has a huge patch of missing hair on her neck. Is this something serious?

  • It’s about 8 years ago. I was wondering how your cat is doing and what was that cause of his hair loss? My cat has a hair loss on chin(neck) area. He has had one hair loss (bold spot, redness) on one of arm about 12 days ago so I took him a vet. She advised us to apply an antiseptic and it seems being healed but he just got another new hair loss on neck and he keeps licking it.

Loss of hair is called "alopecia", and in cats it can have many causes.

  • Obsessive grooming (a mental disorder)
  • Allergies
  • Parasites
  • Fungal/bacterial skin infections
  • Hormonal imbalances

The only way to know what is causing your cat's hair loss is to have her examined by a veternarian. They will do tests on a sample of her blood to make sure that she's normal, and look at some skin cells under a microscope to see if they can find any parasites or evidence of disease.

Once the cause of the hair loss is determined, your vet will give you instructions on how to treat it. For allergies, this can mean a change in diet to eliminate the allergens. Treatment may also include medication and/or bathing your cat in medicated shampoo.

It looks like the edges of the spot are "wet", so either some fluid is leaking from somewhere or your cat is grooming the area severely from discomfort. A vet visit is important to diagnose the problem!

    excessive grooming on a single spot can also happen if there is a wound there, Which may push out the pus Commented Sep 12, 2014 at 12:40
  • Allergies can also cause excessive grooming, in some cases. Vet visit definitely worthwhile.

My cat had similar hair loss too. Often, this is a sign that fungus may be present on her skin. It can be something very serious; I think you should go to the vet for some advanced tests, find out what kind of fungus are there and get the appropriate treatment. Keep in mind that fungus is easily contagious to humans.

Also, this could be a sign of a bad diet, if no fungus will be found then maybe you should control her diet better.


My cat had something similar.its called ringworm.its best to take your cat to the vet as it can grow in size and also spread to other parts of the body.it spreads to other pets and humans also.


This could maybe be something serious or maybe not. Check for Fleas or ticks. Fleas or ticks could be causing your cat to scratch excessively, leading to hair loss. Even if you can't see any fleas or ticks, they may still be present, so it's worth checking for signs of infestation.

Allergies Cats can develop allergies to various environmental factors, including certain foods, plants, or materials. Allergic reactions can cause itching and hair loss, particularly around the neck and head.

Now this is the part where you should sit down.

Parasites, Trauma (Trauma could be cat fight), or Excessive grooming. Excessive grooming aint that bad, your cat does this most likely to stress or anxiety. If you think it could be parasites then get off StackExchange and go to your vet. If its Trauma then pay attention to your cat's behavior for any signs of distress or discomfort. Cats may exhibit changes in behavior if they've experienced trauma, such as hiding, decreased appetite, or reluctance to be touched.

Most of that, you should go to your vet. hope this helps!
