PS: One thing also, esp. if you get babies, make sure you hold them as often as possible, so they are properly socialized and you will end up with some very snuggly, lovey rats. And always keep them in at least pairs, as rats do not do well alone and need a buddy to snuggle with and be 'rats' with. There is nothing like sticking your hand into a pile of snuggling sleepy rats lol. So cute.
