Yes, it certainly is. I came across the Rules For Cats With A House To Run a few years back. It's supposedly written by cats for cats. According to their handbook, your kittys are looking for the bed mice which are said to be almost as tasty as bag mice. In one section, cats are required to hamper any activity by their human companions that diverts our attention away from them. Not only that, a cat's job is to leave his beautiful fur anywhere and everywhere possible. This is one of the funniest things I've ever read. If I can find the website I'll post it for you.
