I work at a pet store. Which is where I aquired my 2 veileds. They are between 6 and 8 months old. They were the only 2 in the habitat and one day we observed them mating. They were purchaced by a customer a few weeks ago and returned about 2 weeks later because the kid didnt want them anymore. So I decided to bring them home. I did my research after the fact due to it being a rather impromptu decision. They are both doing fine. Except I have noticed that both of them have the little notches on their back feet indicating that they are both male. Yet I personally saw them mating before they were originally purchased. Has anyone heard of this happening before?
