Hi guys,
It's been a long time since I had hamsters (I think I had some syrians when I was about 8), but my husband expressed an interest in picking up a pair of dwarf hamsters the last time we were at the pet store, so I'm entertaining the idea (this is the first time he has initialized purchasing an animal).

I have a few questions for those of you that have kept them and would appreciate any other advice you have.

1. Could we house a pair together, if purchased from the same tank (same gender and probably campbels or robos)?
2. Could a pair (or single) dwarf live in a 10gl with screen lid?
3. I know it's a long shot, but would lab block be suitable for them to eat (if not, I will purchase appropriate food)?
4. Would shredded aspen be an appropriate bedding for them?
