What's this rough, bumpy patch with white flakes behind my cat's ear?

This presentation could be due to a trauma or localized spot of skin infection (likely to be caused by bacteria but fungal infections are possible as well). A check up, appropriate disinfection and possibly antibiotics (oral, topical or in a shampoo formulation) are needed to solve the problem. Disinfection may be started at home with very diluted hibiscrub or betadine or salted water baths. Buster collar may be useful as well to avoid any scratching (if any).

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!

Hello! With out at least a picture of the bumps its hard to give you an idea of what may be going on. I can tell you that the most common reason cats scratch there ears is due to a mite infection. Another common problem are polyps in her ear, which are usually in the ear canal and can cause cats to scratch their ears. The bumps around the outside of her ears could be irritation from her scratching the area. Other considerations could be a primary dermatological problem and neoplasia. While age is certainly not a disease, neoplasia is more common in older pets and therefore has to be on the list. I do not think Spicy is any immediate danger. I would recommend having her seen by a veterinarian as for an examination of her ears and possibly some tests of the skin around the ears. Hopefully this helps a bit!

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.

I would recommend having your vet check to make sure she doesn't have an ear infection first. Otherwise, this could be a bacterial infection, ringworm, or even something cancerous. Your vet can take a sample from the surface to look for sources of infection and then do a biopsy (under sedation at a later date) if it's not clear what is going on. Good luck!

The most common cause of itching the ears in cats is from ear mites. These mites are incredibly annoying and cats will do almost anything to make them go away, including hurt their skin as you are seeing. You can try an OTC ear mite medication (see link below), but if it isn't better in a couple days, Sassy should probably be evaluated by a veterinarian. I can't really tell you what is causing the bump between her shoulders. It could be caused by infection, inflammation, or even a tumor. I would recommend that Sassy have this checked out by a vet if it isn't getting better in a couple days. https://www.petco.com/shop/en/petcostore/product/r-7m-ear-mite-cat-treatment-kit

Ouch! Those are some major hot spots in that photo. I would recommend having Lili seen by your vet so the area can be clipped and cleaned and any medications such as pain or antibiotics can be given to help it heal a bit faster. I'd also keep Lili from scratching or pawing at it as this can introduce bacteria and more inflammation which can slow healing. If only Lili is affected and you're not noticing other issues like parasites, etc, it is possible there is an allergy underlying. She could be rubbing up against something causing the itchiness, or could have an ingredient allergy to something in her food (or a treat if the spots correspond with intermittent feeding of a treat or wet food). Other issues such as an underlying illness like an immune or metabolic issue can also cause scabbing and skin issues that affect only one cat in the household. A vet visit is a good option at this point both to treat the current scabs and to see if a food trial, allergy meds, or additional testing such as bloodwork to rule out any underlying health issues may be beneficial in finding the cause.
