I have two mice - Maui and Mai Tai.

I ended up with them when my brother called and said he had bought them for his little girl but his wife refused to have it in the house. I took them because I think mice are pretty cute anyways.

However, they are Petco mice and I've heard they are unsocialized and prone to getting sick. I'm taking them to my vets to have them get a check up - but I'm concerned about socializing them. I have no idea how old they are - and they go flying into hiding when I open the cage.. I know to expect this now - every day I try to do stuff in their cage so they get used to me - including putting my hands down on the bedding so I smell more "mousy".

I also try to do other things (read a book) and put my hand flat in the tank with seeds on it while not really "paying attention" to them so they go on my hand to eat - but so far no luck. I know it takes time, so I'm not worried about it going slow, but if they are too old is there a chance they won't get used to me?
