Why does my cat have reoccurring scabs on ears, lips, and jaw?

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.

This may be a small reaction to getting bitten by something or an allergy to something in the environment. the skin around the scab does not appear to be inflamed or infected and that is a good sign. If it does not go away or begins to spread or bother him, I would see a vet for medication to clear it

Scabs like this could be caused by allergies (food allergies, or an allergy to something in the environment), or a bacterial or fungal skin infection. If you're positive that he doesn't have any fleas, then I would recommend having him examined by a vet when you are able to. It sounds like he will probably need antibiotics and a short-term steroid or other anti-inflammatory medication to treat the problem, and the vet can also talk to you about options to prevent this issue from recurring in the future - such as a diet chance to a prescription hypoallergenic diet, or a daily allergy medication if needed.

That does look suspicious for a bite though it could also be a scab for many reasons. I recommend to have him examined by the veterinarian if there is a chance he got in a fight. Bites often turn into abscesses and giving him an antibiotic as soon as you see the wounds can help prevent that. I hope this helps.

Poor Kitty Bear! I would be concerned that she may have ear tip vasculitis that affects the blood flow to the tips of the ears and can result in crusts and ulcerative wounds. Squamous cell carcinoma is a cancer that can affect the tips of the ears as well but it would be unusual for both ears to be affected. I would definitely recommend having your vet examine her as soon as possible to determine what might be going on. A biopsy might be recommended.

Without seeing the bumps it is difficult to advise you what might be going on with Little Boy. Please repost your question with some pictures of the scabby bumps and where they are located, so that we can give you more specific information on what you can do to help Little Boy.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Blossom! Her skin on her ears looks bad. I think she should see a Vet to diagnose the cause and start treatment. Possible causes are food allergies, ringworm, mites. You can play with her diet and see if changing the protein helps for long term management. If an animal has a food allergy chicken tends to be the most common allegen. But that won’t help her feel better in the short term. Ringworm is diagnosed on fungal culture and mites on a skin scrape. An infection is treated with antibiotics and steroids. I hope this helps and I wish Blossom a speedy recovery!
