I've always wanted to give them a tank of sand.. but can they dig in it? Or does it just collapse on them? What about when it gets mixed with torn up cardboard? Can they make burrows and tunnels?
ALso... Anyone ever give them sand to have pups in? My gerbil originally wanted to have her pups in her sandbath cage (was a small travel cage attached to the tank).. I was wondering, since sand is more *natural*, would they be less likely to develop any kind of respitory problems?
I'm now using corn cob cause I heard it was the safest with pups. But today I was wondering about sand. Or would it not be safec ause it could collapse on them?
