anyone have a uromastyx?

so i was wondering if i could cage a mali uromastyx with a niger uromastyx? i made an out door cage and was wondering if they can spend a few hours a day outside together once or twice a week?

I used to have a mali, he died several years ago.:( not sure if you can pair him with the niger i think they will fight.

Ya i was thinking they would too.... I only ask because i was under the impression that the first one was a mali but now i found out it is a niger so now i gotta build a second outdoor cage
