So I have 2 male rats who I got about a month ago. One is super friendly and climbs all over me and loves when I pick him up and pet him. The other is very shy, which I have no problem with. He hates to be pet and when I pick him up, actually when I pick him up he makes a squeaking sound like I am hurting him and I know I am not. Now I think he just hates to be touched probably because I got him from a pet store and who knows if anyone ever touched him. He has been doing much better and I can catch him much easier. Now he makes this squeaking sound when the 2 rats are playing together also, one would think he is getting beat up but he is not, he will make the noise even when he is on top of the other rat. Well tonight I had them out for playtime and the friendly rat started to make squeaking sounds too as if he learned to talk from listening to his buddy. My real question is do any of your rats actually make noise like this. I find it so funny an odd that my rat squeaks.
