Wow, this thread is getting messy! LOL
About being able to seperate the two... I know food coloring is generally non-toxic (or else we can't eat it, huh? Hehehe!), but the thing is, they clean themselves regularly, so eventually they'll probably lick it all out and you won't know who they are anymore.
Mmm... generally as they grow up, you'll be able to see a size difference, or a slight difference in color. Or if that doesn't even happen, they may have different personalities so that would help. If you really want to attach their names to them, you could probably wait until they're a bit bigger. I'm willing to bet that one will be noticeably bigger (to you anyway, since you watch after them).
And don't worry about the questions-- it's always a good thing to know more about your furry friends, right? 
>>Salt and Pepper say hi And thanks again! Also, I read on a bunch of posts and a bunch of sites that two males shouldn't be kept together. Well, I have their cage that I put them in when I clean their regular cage, so if I have to separate them I can Also, another question (sorry there's so many), they are twins, I mean there is no way to tell them apart...so I was wondering if there is anything I can do to them to be able to tell them apart? My mom and I were thinking maybe taking a toothpick and dabbing a small dot of food coloring on one of their backs?? Maybe that could help? And would that hurt them? Thanks again in advance!
