They are so cute! I have done a fair bit of research into them... You don't see them much, particularly during the day, they are timid and like to hide and burrow.
They are also slightly less tame than regular mice, however with regular handling from a young age, they are quite fine to handle.
If you put them in a nice big glass tank, with lots of branches and stuff for burrowing, they will make a very attractive setup in a living room!
A nice unusual pet. Be aware - like regular mice, they are fairly decent breeders. If you get a pair, they will breed, and sometimes males eat the babies. You might need a seperate enclosure to seperate the male. I would suggest a trio - one male, two females - and be prepared to seperate the male from the young if needed.
