I had a rat before (quite a long time ago). It(he/she?) was albino and I named it Lucifer. Bas**** couldn't be picked up without him gnawing into your finger. I don't know what the deal was, maybe the name? No. Anyways thought I'd share my story.
Hey, hey you have to decide which pet you're going to have, a rat or a cat, you can't have both, one of them is going to end dead.
That brings me to a time when I had an exotic hamster. I found it dead one morning, it's head had evidently been chewed off. Turns out I had rat(s). The moral here is do not magically acquire an exotic hamster, because a rat will chew its head off.
ive got a friend who had 2, and they were pretty fun. they crawl in your shirt and arms and stuff, they are actually good pets. 1 problem: they identify you by your ear. my friends rats would poke their noses into ppls ears to judge them, THEN decide to play.
