My cat has a round lump with a black ring on his nose. What is it?

Hello. I am sorry for your concerns about Clyde. Unfortunately, all your pictures were completely fuzzy, but regardless, it is always best to have lumps & bumps looked at quickly by your veterinarian. Fortunately, most are going to be harmless or benign, but if not, removal at a very early stage is almost always curative. Once you vet has a look, he will recommend the best treatment for Clyde. Thanks for using Petco Pet Education Center, formerly Petcoach.

I would recommend uploading a picture of Yui's nose for us to see. You can resubmit the question and upload up to 3 pictures. If it is not resolving then the next step would be a biopsy of the lesion. That would give us a definitive answer as to what is going on. Thank you for using Petco Pet Education Center, formerly Petcoach.

I would recommend taking Snow White to a veterinarian. This can be anything from a bacterial infection to a fungal infection (like ringworm). They can take a woods lamp (it is like a black light) to see if it glows green. If it does it is ringworm, if it does not it still could be. Only 50% of all ringworm shows up positive with this test. Your veterinarian will prescribe medication to help resolve the lesions. I hope Snow White feels better soon and thank you for using Petco Pet Education Center, formerly Petcoach!

Ringworm is actually caused by a fungal infection (a bit of a misnomer!), so Pickle's deworming treatment will have no impact on the lesion on her nose. That said, ringworm lesions are typically areas of hair loss and dry scaling, and rarely have thick black scabs. It is possible that Pickle injured herself, causing this black lesion. At this point, I recommend monitoring the lesion for another week. If it seems to be going away, there is no reason for concern. However, if the lesion grows, becomes more red or itchy, she should be evaluated by her vet. I hope that all goes well!

Hi there and thank you for using Pet Coach! It is difficult to say from the pictures but because it is black and is on an area where there is not much hair, I am concerned it could be a melanoma, which is a type of cancerous tumor. I would recommend having a veterinarian examine this and consider further testing on this to ensure it is nothing to be worried about. I hope this helps guide you in the right direction! Please let me know if you have any other questions or concerns.

Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It could be ringworm. It does not look like self-inflicted trauma unless you witness Pepsi scratching the face excessively or rubbing against walls / carpets. Please, take Pepsi to your local vets for an appointment. He will be either prescribed cream / ointment that covers both bacterial infection and ringworm infection or your vet will recommend examining skin scrapes under the microscope to make the definite diagnosis before starting treatment.

This doesn't look like a classic ringworm lesion to me, but ringworm can have many different appearances. A bacterial infection or allergy would also be possible. I would recommend having a veterinarian examine Noody to determine what the lesion might be.
