I am really nervous about starting the introduction with Jojo and the babies. I've held the babies outside of the cage a couple times to see what he'd do and he seemed interested and kept poking his nose through the bars but I never had the babies close enough for him to touch them. ((Also did this with Blaze who didn't even huff & puff!)) Hopefully in a couple days my brother will be going back to college meaning I have his room to use for intros. Does anyone have any tips or suggestions? I have a carrier now but I don't know if it'd be big enough? 2 babies rats have plenty of room in it but an adult + 2 babies I am not so sure. Should I do intros with the babies there at the same time? Or should I do one at a time?
