Oh, I like this suggestion, too... And if you worry about people partnering the wrong cats, set the break-up potion down to 100L (Price on that damn thing has been annoying me for ages, lol!) and the mistake would be more bearable.
My cats always have a name - but due to line-breeding, some of them look a LOT like each other, and hence end up with names like "Kitty (Ro-Ru-78-BB)" so that I can more easily keep check of their hidden stuff as well as their shown.... Which is, like Rocky says, a pain to type out every damn time
