Ok, I ordered a T3 for my soon to buy BP. I ordered the cage with one 8 1/2" hole and without the belly heat. I'm wondering how I should plan on heating the cage. Should I have gotten the built in heat AND use a light part of the time? I was thinking of a human heating pad and light but if the built heat is way better I'll change it.

Thoughts on what will heat this cage best? Thanks in advance!
