If it's not getting UVB and is relatively cool in temperature, then it's not processing the stored body fat? I don't know. About 30+ years ago I had a boa constrictor, an imperator, which a friend gave me, his dad had a tropical fruits importing biz in south florida, this was the early 70s when some stuff still came in that hadn't been fumigated very well, and he gave me this boa. Great pet, raised it up from a baby. When it got to around 6 ft long it would feed in the tank, digest, poo, and then pop the top off the aquarium. No big deal because it couldn't fit under the door or escape the house, so we all assumed. For awhile she would wind up in my bed, later she had a favorite place in the livingroom, then she took up residence on my Mom's nightstand, after that on my Dad's nightstand (table next to the bed). Then after a couple of years living wherever she wanted to, she disappeared entirely. Years went by, we just hoped for the best for her. After I'd moved out, my dad was turning my old bedroom into an office, and asked me to come over and get all these boxes of kids stuff out of the closet, so I did, tossed them in the back of the truck, drove them home for a couple hours, Going through them, found the missing boa. She'd been cool for a long time, just sleeping. For over 2 YEARS. She had a big drink and began feeding again. I guess I was around 21 or 22 at the time. Great pet. But my place got broken into and she was stolen along with other stuff.
Many years later there was a petshop that sold mostly imports, they got in a shipment of Asian leaf turtles. Some of them were dried out, about 8-9 inches long, only a couple ounces, dead. I had a mail-order nursery at the time and wholesaled terraria plants to them, they gave me the dead turtles, I thought the shells would be interesting artifacts in the garden. So I took them home and buried them in the back yard. And there they were. About 6 months later we got one of those storms that lasts a few days and dumps 24 inches of rain in 36 hours like Florida gets every few years. The yard flooded as usual. A couple of days later there were Asian Leaf Turtles, re-hydrated, swimming around, foraging. Regained several ounces of water weight.
I don't know if these are exceptions to rules or if something else is going on, but sometimes I hear stories about asteroids hitting Earth and sunlight being blocked out for years, so how would these reptiles that require UVA/B be able to survive without sunlight?
I have no answers, but am quite curious.
The gecko had a bite of a mealworm. Still spraying her every couple of hours. I Suspect she wants to to re-hydrate a lot more before going for the solid food again.
