Don't give up! When my cat was sick, nobody wanted to treat her because she was 15 years old. And she needed a surgery. I went to many doctors until I found the only guy who agreed to perform it... She recovered quickly and lived 4 years after that.
I hope your kitty will be ok! Good luck!
Great story! My cat is very young, he is only 10 month old, but the situation similar - I visited a lot of doctors and every told me different things. Thank you for your support!
