Thank you for the reply. I am worried as I spent my money thinking I will be obtaining a male uromastyx philbyi. If there were not any male availability, I would have saved that money and waited instead.

I started worrying after people identified it as a female and have shown me photos of a 18 month old male philbyi with obvious blue coloration: http://imageshack.us/photo/my-images/403/12269750eee23e2128da1cf.jpg/

I got him/her from Doug from Deer Fern Farms. He has a great reputation so I was not worried initially. I tried contacting him again and included the vent photographs a few days after receiving the uro in hopes that he could ease my worries and confirm the sex of the philbyi. Just in case as mistakes do happen... No reply so far.
