This is all very thought-provoking. Thank you so much for your feedback! I'm thinking it may be gout due to high D3... The articles shared by @DocZ and this article helped me see how gout could be the problem. I'm sad, to say the least... This is so hard. Sounds like the prognosis for advanced gout (or pseudogout) isn't good.
But I'm so thankful for these suggestions. Any thoughts on that initial conclusion? Thoughts on next steps?
Here's my gameplan so far:
- Increase water intake
- But new UV hood with a longer 5.0 t8 bulb (instead of t5)
- Cease all supplementation
- Visit vet to discuss gout possibility, treatment
Thank you all so, so much.
There is one piece that doesn't fit in the puzzle though: The few months that I WASN'T supplementing him at all (following his recovery from edema) were the months that he began his sluggish behavior. That is what led the vet to recommend supplementing again in the last month (which is when I began using Calcium plus and Liquid Vitamin supplements). Could the edema have been caused by renal failure that has escalated to cause gout (for which the supplements are not helping but hurting)?
Personally I would not switch down to a T8. The limited UVB exposure your providing now and at the distance you have it is basically providing the same UVI that a T8 would be. I would upgrade your T5 though to a 24 inch with a 5.0 or 6% UVB bulb and place basking 9 inches below. This gives more coverage of the entire cage rather then one little section. more on lighting https://chameleonacademy.com/chameleon-cage-set-up-replicating-the-sun/
I think you should try to switch to a non all in one supplementation routine. Calcium without D3 at all feedings except two times a month give reptivite with D3 say the 1st and the 15th of the month. Reptivite is a multivitamin and D3.
The sluggish behavior when you weren't supplementing him could very well be linked to the low UVI levels he was exposed to and limited area of exposure.
Right now you are giving him a ton of supplementation though between the calcium plus and the liquid from the vet. Unfortunately only time allows D3 and A to flush from the system since they are fat soluble.
