hello everyone! ive had my FIV kitties for a couple years now and one of them just has the dirtiest ears ive ever seen. ive attached a picture of the aftermath of cleaning them after just a few weeks. she has been checked by the vet multiple times with multiple ear swabs, and theres nothing but normal cat ear things in the swabs. the vet advised me to clean them weekly. i use EpiOtic ear cleaner. she doesnt scratch that them very much but they are definitely itchy and just so dirty. just wondering if anyone else has experience with this or any other advice. thanks!

the pic of her with broken leg is unrelated, it is completely resolved from last year. just for visibility.
