I fed him around 6 p.m. after returning home from vacation (been out of town for a few days). I keep my study fairly dark when I'm not around, so the only light was from my computer desk and his heat lamp. It was also fairly cool (except for his cage of course) in the room when this took place.
I thought about that heat signature / smell as well. But he literally lunged straight in the air aobut a foot. In fact I put the rat in along the far wall, I never held it near the spot Dante struck at. Maybe he was aiming at me. :shock:
