My cat has a white bump on his ear. When should I worry and see a vet?

With a clean ear canal, the most common cause of tiny bumps on the ear itself is related to hypersensitivity reactions from insect bites. The inflamed and sore lesion in front of Teak's left ear is most likely due to self-trauma from him scratching. The concern is that this skin may be infected from the excessive scratching. Your best bet is to take Teak to his vet for an exam because he may need a course of antibiotics and antihistamines to manage this issue. Be sure that Teak is receiving a high quality flea preventative (such as Advantage or Revolution) monthly because flea bites can also cause bumps on the ears. I hope that all goes well!

Ouch! That unfortunately should be checked out by a vet in person, especially if it's growing in size and looking more inflamed than usual, as this could indicate something such as an infection or growth that requires treatment. Typically, a vet will be able to take a sample of the area to determine the exact cells present and what treatment is needed. Until you can get to the vet, placing an Elizabethan (cone) collar on Sebastian may help keep him from rubbing or pawing at it to help it heal. Keeping the area clean and dry may also help. If you're having trouble affording veterinary care, these resources may also help so that you can get Sebastian in to see a vet: https://www.humanesociety.org/resources/are-you-having-trouble-affording-your-pet , https://www.dogheirs.com/resources-affordable-veterinary-care/

Please understand that it's impossible to say what this lesion is with 100% certainty without examining cells from this lesion microscopically. With that said, Tigra's lesion looks as though it could be a cyst. Most cysts are benign lesions. Many rupture and some refill at a later date, but they won't go away completely on their own. It would be best to have Tigra examined by her vet within the next month or so, or sooner if it's changing dramatically or bothering her. Until her appointment, keep a close eye on it for changes, but don't worry about applying any topical medications.

Thanks for using Petco Pet Education Center, formerly Petcoach! It is hard to see well in the pictures. This could be a benign or malignant growth. This is often differentiated by a test called a fine needle aspirate (FNA) which is a pain free, inexpensive and easy procedure which in most cases will help reach a diagnosis. Sometimes a biopsy is needed for a definitive diagnosis. I recommend that you have him evaluated by your veterinarian for further assessment and treatment. I am really hoping for something benign. Good luck and have a good day!

Thanks for using Petco Pet Education Center, formerly Petcoach! These could be benign or malignant growths. There is no way of knowing for sure without an examination though this represents a reason to seek veterinary care. This is usually determined with an examination and a fine needle aspirate (FNA) or a biopsy. Treatment depends on the findings up to that point. I recommend you have Moo evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!

This definitely could be a skin tag and nothing to worry about, but since it is new, I would have your vet take a look at it once to ensure it doesn’t need to be removed. There are other types of skin masses that can look similar to skin tags but are actually cancerous so it is always better to just have someone confirm. I hope this helps!

Hello and welcome to Petco Pet Education Center, formerly Petcoach. The most likely cause for scabs and bumps in that location is scratching due to itchiness, and the most common cause for this is either ear mites or fleas. I recommend using a cat safe flea/mite product. I would otherwise leave the bumps alone, and do not apply any products. If the flea/mite treatment doesn't work, then I would have her seen by a vet to see if there is a different cause. Best of luck with Lydia!
