Ok here's my post in this... My fiance and I have rats!! Cats too, but so far no one has posted any rats so I figure I'll be the first!
These are a Christmas photo shoot my fiance asked me to do with them, We have a naked rat Named May, a black one with few white markings, Peanut, and a cream colored ratty, her name is chai. They are each right around 1 year and 9 months old, so they are getting up there in age, still very spritely though!
May (The nekked one) is crazy, she licks first, asks questions later, and we have kind of labeled her a "rodentist" because she takes any opportunity she can get to try and get in your mouth to clean your teeth! Bleh!
Chai is the smart one of the group, she seems to understand things pretty well, and could probably get her cage door open if she was strong enough.
Peanut is timid, she hides a lot, even though she's given plenty of love and attention, she seems to prefer when we just leave her be!
