my first two hopping mice

These are my first two hopping mice. The one with the short tail is the female and the one with a long tail is the male. I was told by the pet shop that they were both male, so I named the female Bob and the male Terry. They subsequently had one baby mouse, and then a litter of four before I separated the girls from the boys. One day I'll probably set these two up on another date though. Ah, young love.
