What's causing my indoor kitten's skin ulcer? Is it ringworm?

It is most likely ringworm but it could also be skin mites - those are the two most common dermatological problems in kittens. It is impossible to diagnose either of those just by looking at photos. I suggest you try to get her to a vet when you can so they help figure out what is going on. For now, continue with the Ketoconazole.

This looks like a ringworm infection. Kittens do get ringworm especially if they have been sick. You should take her to your veterinarian for a diagnosis and treatment. This isn’t an emergency though so you can wait until next week. This can spread to people so please wash your hands after handling her. With treatment and as she grows up and becomes healthier it will clear up fairly quickly. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Onyx.

I’m sorry your little kitten is having a problem. It is not possible to decide if this skin issue is a bacterial or fungal infection from the photo. Your kitten should see a vet ASAP in order to properly diagnose it. Due to the very young age and small size, it is important to know exactly what type of infection it is, what medication is safe and the proper dosages. The veterinarian can also give a good general exam and possibly check for intestinal parasites as the kitten appears to have a round bloated belly. Please do not attempt to treat this at home because the infection looks quite extensive. Thank you for using Petco Pet Education Center, formerly Petcoach.

Antifungal medication (most likely a topical ointment based on itraconazole or similar) is required. Your vet can prescribe that when diagnosis has been correctly established by some skin testing for ringworm. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

Hello. Without an actual hands on diagnosis, it is difficult to tell exactly what this is, but it does resemble a condition call eosinophilic plaques. If this is what you are dealing with, the condition is frequently associated with underlying allergic disease & tend to respond very quickly to glucocorticoids. The allergies can be to fleas, food, something in the environment & even other insect hypersensitivities like to mosquitoes. The cornerstone to therapy is trying to identify & manage the underlying cause(s). If this is done, the prognosis is excellent for a very manageable condition.

I can't quite tell from the picture but based on your description one thing I would consider would be a fungal infection (ringworm). This is fairly common in kittens. Another possibility is a bacterial skin infection. I would make An appointment with your veterinarian so they can take a look at dusky's skin. There are very simple tests for ringworm if that is a concern for them (they can look at skin with a black light as a screen and can collect fur for a fungal culture) and they can prescribe medication as indicated. Good luck!

You are right to question this. While I can't make a ringworm diagnosis based on visual exam, I can say that Momo has a text-book-looking ringworm lesion. You might consider having your own vet do a pre-purchase exam. You can ask the breeder to send the records. If it turns out that the breeder in not be honest, then that would be a big clue to walk away from this deal. Breeders definitely don't have the best reputations, so I think an independent evaluation is always a good idea. You should also make sure she has received her vaccines and deworming. I hope this helps.
