Cat losing hair in patches

Species: Cat
Breed: mixed
Age: 1-2 years
Our cat has started loosing hair in spots. HE is an orange tabby. White spots started appearing on his sides and we realized it is where his skin is showing. HE has no visible skin irritation just spots with no fur. What could be causing this?


Online vet, Dr. Marie

Dr. Marie replied:

Hi and thanks for your question. There are a number of things that can cause a cat to lose hair in patches.

Does he have any matts in his fur? I have seen a number of cats who had bald spots because they had groomed away a matt. Matts are usually really close to the skin and so when they are groomed away they leave a bald spot.

Is the spot itchy? Does it have any crustiness or lesions? If so, then I would be worried about a bacterial infection or a fungal infection such as ringworm. Ringworm doesn't always have to have lesions, but usually it does.

An allergy to something (i.e. fleas) is possible but this will usually cause scabs and itchiness.

If the spots are not bothering him then it is ok to just leave him for now and see how things go. If he does have matts I would highly advise having a groomer get them out for you and then brushing him regularly.

I hope he is ok!

Dr. Marie.
