Hi, my cat Loki is 2 years old and over the last 8 months has developed an allergy. I have been to the vet and we have tried the usual remedies, changing food, bowls, and flea treatments. The only thing that works is the steroid injection. But after 4 weeks it returns and he starts scratching again. Always around his head and neck. He does not have hair loss just scabs from scratching. We are thinking it may be a flea allergy but not sure. But flea treatments do not stop fleas jumping onto him and biting. We like on a farm and he likes to get out and about and there are plenty of mice and rats around this year. Looking for any advice on treatments, or deterrents. Is there anything like shampoos, or natural things I could use. Thanks
