Seriously, is there anything more fun or cuter then a 3 week old baby mouse ? Xana is an active and happy little girl who has a huge personality in a small body. She loves to climb things, run through cardboard tubes and burrow into some shredded paper. Mice are very social animals and can live peacefully with another same sex litter mate as long as their cages are large enough to accommodate them as they grow. All the mice are 2 for $5.00. We do ask they have a buddy at home or you adopt two, as they are very social and intelligent animals.
