Need help with Uromastyx

[hybrid]

Hi,

I have an adult male Mali Uromastyx that has runny stool. He was recently imported and I got him from Port Credit Pet Centre. Well, he looks beautiful (yellow) and he is active but I'm worried about the runny stool. Are there any steps that I can take to help him? I kind of want to avoid the vet if I can. Is there anything I can do for him in terms of diet, supplement, or heating?

Any suggestions would be greatly appreciated as I would like to get him into perfect health as soon as possible.

Thanks!
