Thanks. I was worried about such a tiny rat being with the huge one...not sure what would happen if they didn't get along. In my short time as a rat owner I've never seen any fighting but I suppose it does happen.Forensic said:I'd keep them apart (in separate rooms) for a couple weeks, to make sure the new baby is healthy, not because of the size issue.
It does happen, I lost a 6-8 week old rat once to a 6 month old rat. They had several play times together before going into a completely new cage to both of them together, but within 2 days the older one killed the younger one. They were fighting a lot but there was never any blood so we let them just work it out.Michelle-Tanner said:In my short time as a rat owner I've never seen any fighting but I suppose it does happen.
