I went out today and bought 2 more female mice so I'd have 3 f 1 m. The pet store I got the 2 from told me both were females but it turned out only 1 was. So I went to feed the male to my ball( breeder said to try live as he's bing a picky ball right now) to see if he'd eat it since he won't eat and I dropped it and he dissapeared! The cats going to get it since I can't find him. How can a pet shop not notice the balls! They were huge. Balls= male simple as that. Well atleast now I have 2 females now.
