I inherited two cats, about 7 years old, from a friend. When I took them, one of the cats had what my friend said the vet called ear mites. She scratched constantly. We gave her ear drops, but they did not go away. Another vet stated that she had a skin allergy, and gave us some topical medication, which seemed to help slightly. The scabs made her continue to itch, however. She is now 12 years old, and she has been to the vet numerous times. They have given her shots, drops, injections, but nothing seems to get rid of her constant scratching. She makes her ears and her chin and the area around her mouth bleed from the scratching. I am taking her to the vet again, but I would like to know if there is anything I can tell the vet that might help alleviate this problem. I heard that some cats can have blood cancer which causes them to scratch, and now I am very worried. Will we ever figure this out?
