Even suitable for dwarf hamsters, with adaptations!
I bought one for my dwarf hamster - though the description says it's not suitable for them due to the gap between steps (which is correct), I've put a wooden ladder up to the top step, with the boost from a bit of bedding the bottom step is entirely accessible, and the middle one is accessed by jumping down from the top, which she's quite happy to do. It would be perfectly sized for a Syrian or rat.
Good value for money!
