I through in some pieces of wood blocks and they have some cardboard in their as well. They poop like crazy, floor is already full of little raisins, but they don't seem to smell. I also put some Vanilla in the water bottles, so far so good! They sleep most of the day.
The male I have is about the size of a medium rat and the females are somewhat large rats when compared to the RodentPro feeders I get.
When should I begin to expect pups?
