My cat has been diagnosed with urinary tract infection; I have been given the medications and started the treatment around a week ago. He doesn't seem to be in pain anymore and there's no blood in the urine, but his attitude still worries me a lot. He is still most of the time, just laying down around the house and almost doesn't touch his food, I've tried offering him different things from fish to meat but he barely touches them if at all. He usually is more active than this, so it makes me very uneasy.
