I have a few questions about Chadwick's vet visit yesterday. First, Chadwick has the sweetest disposition. He's always so friendly with humans and animals and I have never heard him growl of hiss... until now. When we got into the waiting room, the cat that hangs out there looked at me and Chadwick had a fit! He was growling and started hissing like crazy! When we got back to the exam room, he was still going at it and even attacked me! I was so upset that I almost cried! I tried telling the vet that he's never acted like this and she told me that if cats experience a traumatic experience (last time he was there, he had to stay for 2 days), they become more stressed. When we got back out to the car, he was the usual sweet Chadwick. I wonder if he got that upset from that one cat, maybe I shouldn't get a new kitty! Another thing I worry about is that Chadwick eats blankets and towels and will cough up "hairballs" a few days/weeks later. It freaks me out because I'm afraid he'll get an obstruction. The vet told me to change his food and try a wet kind and get more interactive toys. He has a toy box and all of his interactive toys, he breaks. Also, he has a lot of tartar buildup and we think by watching him eat, we aren't sure he's really chewing his food. Have you all found any dental treats that work well? Any ideas????
