If you go onto a dedicated degu forum like the "Degu and Chinchilla World" forum or "Degutopia" you will find all of the information and help/support you will need.
Degus are complicated creatures needing alot of cage space, special food (they can't have sugar and need Vitamin C in their food), and having many medical issues due to inbreeding. Also, telling males and females apart is tricky. Many pet stores do not know how to do this because they aren't like rats or gerbils or hamsters where it is easy to tell. I adopted four 'females' from the local animal shelter and they ended actually being three females and one male. That's why I now have 16 degus. This happens more often than you can imagine. Please check one of these forums to help you make sure you are getting all boys.
