I was curious as to how long heat tape generally lasts? How long can it be used and when does it need to be changed? I recently got a Animal plastics rack system with 4 slots and heat tape on each slot. The rack is hooked to a thermostat with a probe . It was purchased in January and has been previously used for a few months . This is my first time using a rack and I wanted to be prepared for when I may need to get more heat tape. Everything heats well so far, hot side 90-93 and cool side 82-84

As for the behavior of my balls, they don't try to get out of the tub too often unless it's around feeding time. They seem pretty content in the tubs. The "trying to get out" behavior stops after they are fed. No one is showing signs of being too hot or restlessness. Humidity stays in pretty well and reaches around 70-80 percent at the highest. Usual humidity stays around 50-60 percent. Hope this extra information helps .
