Dianne,
Good to know BP's will often take several or more smaller prey items. My corns will do that happily, and I am sure my Boa would too. However, my BP is a shy eater, and usually goes and curls up after a meal. She's not exactly looking for more. However, she's always eaten appropriate sized prey for her and switched to rats super easy. So, I haven't had to test the theory. I appreciate the insight.
Secondly, you got off light!
Shayna (my BP), will, every once in a while, pull the rat into her hide, where she likes to eat, and then leave it there. The first time she did that, I didn't find it for two days! It was horrible! I give her two days to digest and leave her alone completely. Well, I used to. Now I check the next morning under all her hides to make sure it's in her belly!
