When I picked him up that evening, they told me that he had managed to chew or scratch out his first set of stitches and had to be resutured. He would need to wear a cone or a shirt, preferably both. When we got home the cone seemed to be making him panic, so I quickly made a shirt for him out of an old green t-shirt of mine. As soon as he was feeling better, he just as quickly squirmed out of it.
Shirt number two turned out a lot better! I made the neck narrower so it would be harder for him to get his arms through the neck. And it looks much better on him. I also reinforced the armholes since his escape strategy is to lick and bite the armholes until they are stretched enough that he can somehow get his arms out and slither out of the whole thing.
With all of the weight he has lost, the shirt makes him look very svelte!
Poor little guy -- the vet also found that he has bone spurs on his elbows. That means that he has arthritis. It doesn't seem to be slowing him down at all!
