I used to remove all the furniture in the cages, but i figured out it makes no difference to them. I'll open both boxes and heat up both f/t critters with a hairdryer, and i'll feed my little spider first since she's more food aggressive, that way constantine will have some extra time to get her appetite up and wake up. For her, I have to leave the rat in her hide for her to eat at her leisure, and i have to be far, far away for her to eat. sometimes I have to turn the light off, but sometimes I don't.
