They get bored

Glad she already had her babies, an hour or two earlier and she would have bolted!
Guess the mother in her told her to stick around.

Yes they do, dont they? I.. I mean my Mom has 1 or so female rats she LOVES.. and the boys And well we keep them in 20 gallong longs, with the females top off and a large wheel in there. they LOVE the wheel. Something I would recommend to any who has rats. They dont like the mice/hamster wheels, they are too small and closed in, a wheel with both sides open. We use wire-like wheels, that we bought from petco. Our adult and young rats LOVE the wheels.
