Vi Co Bi-

I can relate to litter mates hating each other. I've posted the story before about a kitty I was fostering who had two kittens in my closet. I kept them after their mom went to her new home, but they never Got along. They hated the very sight of each other and would fight if they happened to come within feet of each other. They were like this until they day they died (tragically, together in an accident) four years later.
