My rats do that 24/7, especially at night, causing such a rukus, I can't fall asleep. Daisy & Chloe are the youngest (only 4 months), and they have a lot of spunk, and love to beat up on Oscar and Fred. It's pretty cute to watch. Sometimes they get really nasty, and pin down eachother, and make eachother squeek. It looks like they are trying to kill one another.

Don't worry, what your rats are doing is normal. It's playing.
