Groucho is a black and white kitty, cute as they come. Anyway, I stopped in at a small pet shop near where my son was working at the time to pick up some food for our RB parakeet. A sign in the window said they had kittens so of course I had to check them out. When Groucho popped his little head up I instantly fell in love with his Groucho Marx moustache. Everyone who sees him says, "Yeah, that's a Groucho" The name just took.
