I purchased it on 02/16/2021 from store Petco... i didn't ask them how old it is but looks young. He was nice and in peace unitl i showed him my roommate his female hamster. If i let him out he only just want go.... if you have females hamsters and looking for boys.. you will be the right person for him.. i will also give the cage for free as long as you can taker of him.
