That pic above, taken in '99 on our farm in western Minnesota, is Thor and Bill. Those two were buds. I don't think Bill ever really knew he was a cat and not a dog. Or maybe Thor never really knew that he was a dog and not a cat.
Anyway, Thor is 15 now, and three-legged, but he's still kicking.
Below is Buck, who passed away two years ago at age 13 from cancer, Bill, and Thor again.
