Thanks Grif! I have been using Calcium with D3, no UVB. Everything I read, including the care sheet here, says the same. The vet said he needs a small amount of UVB or he can't metabolize the calcium, even with the D3. I know this is true for bearded dragons, not albino pacmans.

I haven't noticed mucus in the urine, but he always jumps in his water bowl to go. I'll keep an eye on it. Really hoping it's an infection. Sorry about your recent loss, they are chubby little family members!
