Why are my cat's ear and neck scabs getting worse after treatment?

I would have to agree with your vet's plan, especially if fleas and ringworm have also been ruled out. Often we just don't get the answers to simple skin problems with simple tests, and we have to biopsy. I recommend submitting the biopsy for dermatopathology - that means a pathologist with special training in dermatology will look at it - and this can mean the difference between getting and not getting an accurate diagnosis. Cats can have some very strange skin diseases, especially around the head, and getting an accurate biopsy will help to get Annie the treatment that she needs.

Hi. This looks pretty severe, and it sounds like you have done alot. This could be allergies, food sensitivities, immune mediated skin disease, or more. Since you have been battling this and not much is working, i would recommend seeing a veterinary dermatologist as your second opinion. this would be the most helpful

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.

If you have ruled out fleas/skin mites. I recommend to have him tested for hyperthyroidism and if that's not the cause, have him on a 12 week food trial with a hydrolyzed protein diet. You must start moving down the list of potential causes of the skin lesions. Atopy is still on the list but is harder to test for so rule out these other causes first. Best of luck and please feel free to post any additional questions.

Skin cancer is unlikely at that age. It is more likely that there is an infection there which did not clear up as antibiotics are needed. Bite wounds must be considered always infected. A check up is needed. Your veterinarian will flush the wound first and prescribe local or systemic antibiotics.

It sounds like you are doing a good job ruling out the usual causes of chronic skin disease. You have one more month before you will know if its food (it takes 3 months to reset the immune system). I would recommend ruling out hyperthyroidism (although this typically affects older cats). Otherwise environmental allergies would be the most likely cause. These can be to ANYTHING (house mites, dust mites, grass, pollen..etc). I think you guys are on the right track. Keep going and best of luck!

This is probably due to an allergy, although it could also be infection or mites. First of all, in order to rule out skin parasites, you will need to treat with a high quality flea treatment (advocate or advantage), then ask the vet to perform a skin scrape - this might reveal an infection or a mite infestation. If all of those came back negative, the next step is to treat the allergy symptomatically and try to discover the cause of the allergy. Three main type of allergies are usually affecting pets: food allergies, flea and parasite related ones and environmental type (allergens coming from trees, pollens, dust etc etc). Some medications can be given by the vet in order to repair any possible skin lesions (like steroids and antibiotics).
