What's this crusty, bald, black spot on my kitten's ear?

These skin lesions look like bacterial or possibly fungal infection. Mites can be responsible for it as well. A clinical examination at your local veterinarian is essential to confirm these clinical suspicions and treat appropriately. Antibiotics may be needed. Hope this answer was helpful, but 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.

Congratulations on adding Tiger to your family! There is a chance that its bacterial but I would be most concerned thats ringworm (which you can get from him!). I would recommend to take him into the vet for fungal testing and medications to start treatment just in case (while you are waiting on the results). I would also recommend to start him on a flea treatment such as Revolution as this will provide longer protection than a bath! Please let me know if you have any further questions!

This looks like a ringworm infection. That is a fungal infection common in young kittens. Since it’s only a few spots your veterinarian may prescribe a topical medication. They will look at this under the microscope and may do other tests to confirm the diagnosis. People can get this so please wash your hands after handling her. Thanks for using Petco Pet Education Center, formerly Petcoach to help you care for Princess.

Poor kittens! These lesions could be a result of injuries from playing and subsequent infection/abscess formation, ringworm, or mange. If you feel adventurous, you can carefully try to use clippers to clip the fur around these lesions on both kittens and then clean the areas with an antiseptic solution, such as dilute chlorhexidine or dilute betadine. However, both kittens will likely need to go to the vet for further evaluation to determine if diagnostic testing and/or oral antibiotics are necessary. If the kittens are scratching at themselves, be sure that they are wearing e-collars (cones) to prevent further skin damage. I hope that all goes well!

The picture is not very clear, but I see some crustiness and possibly some hair loss. I worry about ringworm (a skin fungus) with that type of lesion, because this is also a very common location for ringworm in kittens. It could also be some other infection or due to a scratch or bite. It is not normal though and to determine the cause, you would have to bring her into the vet for an exam. They can take a sample (if needed) and look at it under the microscope to find out what it is. For now, it's best to consider it contagious, because ringworm can be transmitted from cats to people. This is usually self-limiting (will go away on its own), but may need treatment if you start to see more lesions. You can wash it once a day with medicated shampoo labeled for cats (can be found at the pet store). This will help if it is an infection.

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.

This is very suspicious of ringworm (a fungal infection of the skin). This could also be due to a yeast or bacteria infection, but it's much more likely to be ringworm. . It's best to get it diagnosed by a veterinarian, because ringworm can spread to different parts of the body and can spread to other animals and people. Also, the more involved the infection, the longer it will take to clear. Ace will need prescription antifungal medication in order to clear this and will also need medicated baths. For now, I recommend separating Ace from your other animals and washing your hands anytime you touch him. Your veterinarian will be able to get you some more info at the time of exam. I hope that helps and Ace gets better soon.
