It shouldn't be this difficult of a decision, should it? Just call them whatever you want, depending on your mood. Cats are too stupid to complain about their names, right? You could call your cats "stupid ugly faggots" if you wanted to, and they would accept it jubilantly. That's just the nature of animals, man - they don't care what you call them. However, if you're one of those guys who treats his pets like he treats his kids, then I suppose there's no harm in waiting another week or so before ultimately deciding on their names. Whatever you do, though, don't name them anything generic or overused.
Additionally, avoid ultra-gay names like "Alex" and "Miki", for example. Your cats may not care what they're called, but even the daftest of cats can object to those abominable "names".
