I have two rats Splinter and Mecha I am new to being a rat owner and am really enjoying how sweet these little guys can be. My question is when two rats are playing together is it okay if one bites the other and pulls it. Now I am not talking a hard bite that will make them sqeak I am talking they grab the fur and drag their friend a little then drop them. Since I am new to this whole thing I don't know if that is just how they play or if they are being agressive?!?! Thanks in advance for the replies.
