I hope it's an easy fix. His teeth look okay, he doesn't act like his mouth hurts him, and he still plays with stuff. His over-all attitude is still loving and purring. He doesn't act like he's sick or hurt, so I don't know. He's just a little clingier than normal.My oldest cat (she just turned 17) started losing weight very fast, turned out that her teeth were in terrible condition and it hurt for her to eat. She is still skin and bones, at her age, but, I was happy to learn that the problem was her teeth and not cancer.
I hope it's nothing serious, I'd hate to lose him. I've had him almost the entire time I've been married to my hubby.Hang in there, sometimes it can be something they can treat easily too. I have seen both.
