Phil- No warfarin in our house.
These boys are littermates so they only "fight" to establish dominance. Fighting is a bit of boxing and rat wrestling, one gets the other in the "say uncle" position. It's actually kind of funny to watch.
Ann- They are very tame. Before I got them the girl I got them from said rats are like little dogs and they are. They have learned their names (Nip and Tuck), come when they are called and love to get petted. They are also learning to use a litter box. I think hamsters are really cute, but rats have a better personality, plus they don't stink as bad as the hamsters.
John- You are so funny. I like the beaureauc-rats! thing, I am just glad my rats aren't DemocRATS.
