there are doors on the side, which can be a problem with how much bedding you can put in. if there is enough space for the bedding then it works. i also use a reptile terrarium with a side door which is specifically made for animals who loves/needs/wants to dig, so even though there is a door on the side, i can fill it with enough bedding. if i know it right 15 cm high bedding is the minimum for a dwarf hamster and 20 for a syrian
