What are these spreading skin wounds on my cat? Are they contagious?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | unneutered | 3 months and 30 days old

So my cat have recently developed such symptoms... First i thought he got it in a play with other cats but now they don't seem to disappear and our other kitten have developed such wounds too. Before i take them to local veterinarian i want to get as much answers as possible... I'd like to know what this disease could be, how difficult is it to cure and if its transmittable on humans? Thanks

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor kittens!

Until you get a diagnosis from your Vet I can't answer you on if it is transmittable ti humans. You may also have different diseases in your country than we do in the US.

Possible causes of the skin condition are: fleas (people can get bitten), allergies to food or environment (not contagious), demodex (mites not contagious to people) or ring worm which is a fungal skin infection (is contagious to people).

Fleas are easy to fix. Allergies are frustrating and can take a while to find the medication and food that works. Demedex is relatively easy to fix. Ring worm can take a long time and oral medications and lyme sulfur dips.

I hope this helps and your Vet will be able to get you the diagnosis. I wish you and the kittens the best!
