Everyone of them is different I hear some are shy and stay with you and don't explore, but you should expect them to:
sleep all day maybe let you pet them in pouch and take a treat or two
At night they run jump bite everything like a kitten on all the crack in the world
They are small and get in to everything
Most of play time is finding what I missed glider proofing the room
Vet bills are expensive, think twice or more what you pay for them if they get hurt
if that doesn't sound like fun thin maybe not the pet for you
Food is not to hard bml (what I feed ) takes a few minutes to blend freeze and scoop nightly add fruits and veggies
The best parts are
chasing a scrap of paper as you drag it on the ground till they find your fingers lol (they draw blood easy) their teeth are really sharp sometimes it doesn't even hurt I'm just bleeding.
When they start to trust you and jump on you if something scary happens, it's super cute how they hide and peek at what ever it was.
Maybe even let you pet them as they bite the holly crap out of something that isn't your hand.
When they really love you they will pee on you, in your hair, several sports on your pants and/or shirt, that's when they start biting less.
I love mine but I wish someone had told me those things first not that it would have changed my mind
I have lots of pets that want to bite my face off lol
Not to discourage you from getting them
just my experiences yours might be different
