He has lost a lot of weight lately. I noticed he was skinny but it's one of those things where if you see someone everyday, you don't notice right away. I really realized how skinny he has gotten when I was looking at pictures from last Christmas. He still has a great appetite, going to the bathroom fine, everything else, fine. So, through my internet research, it's probably his thyroid. I just pray it's something that can be fixed and that it's not too late. He just turned 14. DH is off from work this week so he's taking Figaro either tonight or tomorrow to the vet - first appointment he can get.
