I do. I usually start off the conversation to my rats when I go into the garage to tend to their needs with "What up, ratties?" "Ratties" is pronounced "rattehs". I open up tubs and say "what up? Doin ok? Good. You wanna bite me? No? Thats good too".
Even know I gas their babies and feed them to my snakes..... I really like them. I always feel bad when uthanizing though :/
