I've had my rats for almost a week now. I was really excited to get them and I'm still so happy to have them, but there seems to be very little change in their behaviour towards me. They run from me or flinch away if I even try to gently pet them. I've been trying to bring them out of the cage to get them socialized but I can't put them down (I hold them in a blanket) as I'm afraid they'll run away from me and get hurt or stuck. They just seem terrified of everything. One is a 4 month old female and the other is her 6 week old baby. Is this part of the problem? I was thinking of getting one more, better socialized rat--I already know of one--to help them become more social? Have I made mistakes by getting a momma and baby? I want them to be able to be happy and get exercise. Please help!!
