We have 2 female rats in a big cage. They are about 3 months old and seem to be fighting a lot at the moment. They sleep together in hammocks all the time, and have plenty of time out of the cage (when they don't fight) but there is a lot of squeaking and chasing and clawing going on in the cage with one seeming more dominant than the other. To date there has been no blood shed! Should I be intervening?
Thanks
