bro...if ever you have an actual picture of what is happening to your MBT's..maybe i can help you with that..

cause it is hard to imagine, unlike humans na mka ask rka sa doctor w/o showing up, lahi mns sa animal world..
Anyway...as a piece of advice... let your MBT's bask for a couple of minutes daily..they need (badly) sunlight to metabolize calcium present in their body..

if you are looking for heat lamps...you can find it at legends trading (kinasang-an pardo) or at pipers pet shop (banilad, near BTC)...
