Well, I'm running out of ideas.
Khalil doesn't appear to be in dire straits, but neither is he back to normal. It's 8:30 am here, and he's still asleep, 3 hours after his lights went on. He was asleep when I got home from work at 6 pm last night. He doesn't bask at all unless I put him up there. He does eat, but it's only sporadically, not like normal when at 7 am it's like "Where's my food??" (Yesterday he ate somewhere around 20 crickets.) When I wake him up, he seems fairly alert and frankly, a little bit more cuddly than usual (less anxious to escape). When I put him in the tub he swims around pretty heartily.
The vet is convinced that it has to do with his bowels, and wants me to give him warm baths twice a day to help keep things moving. (This is the first time I've seen him. He seems like a nice guy, but I have no idea how good he is. He IS an exotic pet specialist, not just a general vet, though.)
The light/uv situation is not resolved yet. He's still on just a household bulb and a heat projector that combine to make it about 97 in his basking spot and 78 elsewhere. I haven't determined whether to go with a different UV or try the Mega-Ray again. He doesn't show any of the signs of beardies who had the "bad" MegaRay bulbs a few months ago (swollen eyes, etc.). At this point he's been without UV since March 23rd.
Just thought I'd share where things stand!
