Over a year ago I rescued approx 18 month old cat and her son now 1. After having the mother for about 6months I noticed she started licking her back and base of tail and stomach area. It soon broke down and was left with no hair she licked that much she caused wounds. The first vet I took her too said it was either stress or allergies, she received a steroid injection for this. This help which led the vet believe it was allergies. I did not re attend that vets due to him being rude at first. Anyway after appox 3 weeks we where back to square one. I have since given her hypoallergenic food, fleas her and other cat every month. She doesn’t seem stressed to me always having her food, wanting fuss and behaviour seems normal apart from the this constant over grooming. She has methopredsinole a steroid injection as tablets do nothing. She has probably had over 10 injections sometimes they work for 4 weeks and sometimes they do nothing. I have had another cat in April last year they don’t practically get on but her problems started way before this. I have feliway plug one for calming and then a friendship one and have seen no results. She was a stray before me having her and I find it so upsetting her skin and fur was prefect before coming to myself .looking for advice on any treatments you have used that work?
