Why does my younger rat bite and pull on my older rat? I've had to separate them, but I got the younger rat for company for my older rat.

Answer

If they're both the same gender and you've had the older rat longer, they may be establishing a hierarchy. The younger rat, especially if he is a male, is probably trying to assert dominance. It is best to get rats of the same age at the same time to avoid this problem.
