Uromastyx sleeping all the time

Question
I have two Mali Uromastyx that are less than a year old. Lately they have been sleeping for days at a time without getting up at all. I wake them up some times to eat and they will some times eat but otherwise go back to there hide out and go back to sleep. Are they sick are am I doing something wrong. Thanks

Answer
 I suggest you separate the uros very quickly.  Uros have to brumate (a sort of hibernation) before mating.  To have a male and female in the same tank at this time will stress the female after mating because shhe cannot get away.  The male will want repeated matings while the female will not.  And they should not mate this young at all, and depending on how you got them, I would be concerned if they were siblings.
