Steppe Lemmings are not actually lemmings, they are Voles. they are tiny..the reccomended tank size is 10-15 gallons for a colony of 3-8! they eat budgie seed or degu food, and low sugar veggies, and their bedding is mostly hay with a thin layer of wood chips. Steppe Lemmings cannot jump up, so unless you need to keep something out, they do not need a lid of their tank. they are super curious, and diurnal, and noted for being extremly easy to tame. they MUST be kept in a tank, under no circumstances can they be in a cage that is barred anywhere as they are very small and can squeeze their little bodies flat allowing them to walk right through a barred cage! they are not known to be very bright, but they are are funny, friendly and curious! they LOVE to climb up on stuff, but you just have to make sure the fall wont be very far because..as I said they are not to bright..they will fall off of anything they climb up lol
