Exactly what I believe as well. It would be interesting to try to feed it an unheated room temp FT rat and see if there is a difference in feeding response with a heated up rat. I would think that would put the heat pit issue to rest one way or the other.

Doubt that would work well, I get a huge reaction from heating up a rat from my colubrids too. The heat releases good scents. It's like offering a warm cookie fresh from the oven instead of one thats been sitting on the counter for a week. It wouldn't be an accurate way of testing a BPs thermoreception.
Accuracy or strikes in a dark room of a heated vs. unheated rat might give a better indication.
