i have had a rat for a couple months now and since realized that they are the type of animal that does better with a friend vs. being alone so today I brought another rat home. I let them run around together to get to know each other a bit then put them in the cage. They seem to be wrestling a lot and my new guy Squeeks a lot and I’m worried they are fighting. No one is hurt or bleeding. I read that it’s just a dominant thing, but I just want to see what other people thought.
