I have two rats, about 4 weeks old. They are black hooded. They are extremely tame, since I've been handling them since they've been little bald pups. They were growing to be food for one of are large snakes, but she may be adopted.
I've grown fond of these little comedians, and I hope they are adopted out as pets or breeding for feeders (I'm almost positive one is male and the other is female. ) But if no one shows interests in them as either breeder or pet, I'll let them go as dinner for someone.
They don't have to be adopted as a pair. If you want a pet rat, I'd suggest not adopting both, because you'll end up with 100s of babies.
Pick up in Westfield or Springfield, MA.
