I think quite a lot of people use those as play pens but you would have to supervise carefully for chewing & escapes, I would guess a syrian could probably climb out without too much trouble!
Cheapest is probably a home made play pen with cardboard, not so cheap but more ham proof is correx, I just cut sheets to size & fasten at the corners with cable ties so it just folds flat when not in use.
