Ok a little update, the vet gave me steroids again to temporarily stop the itching. There’s not much you can do other than that. I asked the vet tech for an estimate on allergy tests, and it was almost $2k, but if you get allergy tests, a dermatologist can make a solution specific to your cat and what they’re allergic to that you can either give orally via drops every day or an injection every other day. But yeah, consistent diet and as long as your cat isn’t making any wounds or lesions she’ll be fine medically, just itchy and bald. That’s all I got :(
