You mentioned fleas, did they check for ear mites?
My cat did this for almost two years, sounds the EXACT same!! The mites were way deep in there I guess and the vet missed them for the longest time. We tried everything, I had been cleaning her ears with wipes one day and saw a little tiny moving dot. Called the vet like “I think there’s a bug in her ear?!?” and they gave me some ear drops, few weeks later they were gone and she hasn’t once scratched herself bloody ever since.
My thinking is, for all I know, the 5 year old reputable account accusing me of being a bot was just sold to some spammer and it is now posting with AI. I know I’m real, the conversations provoke my consciousness and cause me to have new thoughts, and that’s what I’m here for. Like, no offense everyone, but unless we’re gonna meet up and hang out, it doesn’t really matter to me if you exist or not lol
