QUESTION: Oh sorry i thought id put how many were in 1 cage. Theres 3 of them

Answer
Often males will get kind of weird when there are more than 3 rats....the alpha role and all that stuff we dont really understand when it comes to rats.  At this time he sounds like he is just a  bit more fast and furious than the other rats but he doesnt seem to appear abnormal. If he is indeed around 8 months old, hormones and high levels of testosterone also play a key role in behavior, from a bit of aggression with the other rats to acting downright strange.  Once he passes the 12 month mark he may chill out some.
