Alright, I have one rat Maru-dashi and Ive had her since she was a baby. Then I got another female from my friend because I didn't want maru to be lonely.They were about the same size and same age and seemed to get a long....some scuffles but not too bad. But I noticed the other rat would squeak when Maru was cleaning it. I got rid of the other rat after a few weeks but the squeaking while grooming continued the whole time I had it. Today I was in the pet store and did another snake food rescue and bought a tiny baby rat. About 1 1/2 inch long...about the size of a large mouse. I introduced it to maru and she seemed excited, but again with the squeaking, and with a rat this small this is a problem. Does anyone know whats up with maru...cause it kinda sucks because I don't really have a "rat" cage, I've just got a few tables with boxes and old shirts thats dedicated to maru. I've stuck the baby in my empty tarantula cage for when I'm not around to break it up, but I really don't want to have to leave it in there till it's big enough to fight back. Any suggestions? Is it happy squeaks (don't really think so I saw scabs on the first rat) Is my rat messed up in the head (possible) or is it a dominance thing? Thanks and sorry this is so long.
