OMG I love them!! I love the tan hooded with the red eyes!! I'll have to get some recent photos of mine (I have two ratties hehe).
I agree they do make GREAT pets and I've never had an incident where mine have bitten me and I try to fool around with them as much as possible so if something happens I will be able to look at them without them struggling to get free.
I wonder what my ratties would do at a park...the one would stay calm where as my other would probably say "OMG I'm freeee" and run away...she's my little excape artist lol
