My kitten has a mouth sore with hair loss. Is it an infection?

I would get this seen by your vet to be on the safe side. It may be a healing scab but it looks a little suspicious of ringworm, and that can be easily spread to other pets and people in your household. Another possibility is an allergy to plastic if they have plastic bowls for food or water, but those lesions tend to be located on the chin and lips, not to one side. Your vet will do an exam, probably pluck some hairs from that spot for a fungal culture and may examine some of the cells under a microscope to see if they can identify the cause. Based n these results they should be better able to tell you why this happened and how best to treat it.

Yes. Especially with kittens, ringworm (which humans can get) and bacterial infections are common. It’s best to get a handle on this early. I hope this is helpful and please feel free to post any additional questions.

Hello, thank you for using Petco Pet Education Center, formerly Petcoach. It looks like a superficial skin infection. It does not look serious at this stage. Sometimes this happens randomly, somteimes it is due to a bad tooth. The saliva has bacteria in it that gets on the skin and can cause this infection. The vet needs to check her entire mouth. Don't bother trying to clean it at this stage. Just let the vet look at it first.

She could have a infection or allergic dermatitis. You could bathe her with a medicated cat shampoo and see if that helps. Otherwise, have your vet take a look at her to determine the cause and treat the problem. She may need an antibiotic and/or anti-inflammatory to treat.

This sounds like a viral infection. It is something to be concerned with as it can develop into an upper respiratory infection and cause a decrease in appetite. As long as she is eating and holding her eyes open, then having her checked at your schedule appointment will be fine

I am sorry to hear about your kitten. It looks like she could have an infection of the skin around her mouth, such as perioral dermatitis. This requires treatment wtih antibiotics. I would recommend having her examined by a veterinarian who can then prescribe medication to treat this condition.

Given the red and irritated appearance of Nellie’s skin, I’m concerned that she either has a skin infection (usually from excessive licking with underlying allergies) or an allergic reaction (contact dermatitis) to something in her environment. The white plaques appear to be skin crusts, which can occur with either of these situations. At this point, your best bet is to take Nellie to her vet for evaluation. She may need a course of antibiotics or topical medications to get this issue under control. Until her appointment, be sure to keep an e-collar (cone) on her so that she doesn’t lick herself and make matters worse. I hope that everything goes well!
