Cat are amazing animals. I know that they’re one of those love them or hate them beings to a lot of people, but I think I fall in the love them category. Like you, I’ve often been left wondering at why they choose such interesting places for a nap - especially when their naps often last so long.
Sorry to hear about your experience with the doctors. Unfortunately a lot of educated professionals you could once rely on are now no more reliable than anyone else. I really struggle to find GP’s much better than the internet and view them as a stepping stone to specialists who still seem to know what they’re doing. Let’s hope that regardless of the incompetence of your doctors, the medication they’ve given you works really well and you’re back up to full capacity quickly.
