There are those who will say that dogs and cats are always natural enemies. That may have been true hundreds of years ago when canines and felines were competing for the same prey, but I contend the relationship today is much more complex. I give, as example, the friendship of Boots and Butch.
Boots was an orange Tabby kitten, with huge white polydactyl paws. He was a neighborhood stray, being cared for temporarily by friends who suddenly had to move. As the last box of dishes was being loaded in the rental truck, my friend asked, "What are we going to do with Mittens?"
