Just a real quick note to let everyone know that Odin was at the vet today. The vet did a full exam, including x-ray and didn't find anything wrong!
The vet suspects that Odin is actually older than we were told, and that he is just slowing down a bit in his golden years. I am sad about this, as I want as much time with him as possible, but the vet felt that there was no reason he wouldn't live to be an old old cat.
Thanks for all the positive thoughts.
