My cat has a large ear growth that doesn't bother him. What is it?

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!

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/

Thanks for using Petco Pet Education Center, formerly Petcoach! This could be a benign or malignant growth. 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 Reggie evaluated by a veterinarian for further assessment and treatment. Good luck and have a good day!

This is a seriously big tumor and needs to be removed ASAP before it spreads to thee inside of the ear. It is obviously painful or bothering the cat, which is why she is scratching it drawing blood. This in turn may cause infection. Please encourage your neighbors to take Baby to a veterinarian and have that tumor removed surgically.

I am sorry to hear about your roaming kitty. Unfortunately there is no topical medication that is going to rid the kitty of this growth, which could be a large polyp (benign other than causing irritation and if removed cat may go back to normal) or a tumor.

Your suspicions are right. This is a skin mass unfortunately. Due to the color, I would recommend having Nanni seen by your vet and the mass sampled to see if this is cancerous or benign (non-cancerous). Hopefully it is not cancerous and we can just monitor it. But if it does end up being cancerous (after viewing the cells that make up the mass microscopically), then removal of the mass can be discussed with your vet. I wish you all the best moving forward with Nanni. Take care!

Thanks for using Petco Pet Education Center, formerly Petcoach! There can be multiple causes for a small bump on the tip of a cat's ear, such as a cyst, focal infection, small growth, or another underlying medical cause. It is difficult to advise you further about Timon without being able to see what you are, but if you are concerned or if this developed quickly I would recommend having him evaluated by his regular veterinarian to determine what may be going on, and if any treatment is needed at this time. Good luck!
