I picked up a spider at the pamona show on sunday and today fed him a rat pup. He became interested immediately, but when he struck, it was rather half-hearted. When the pup squirmed, he clenched up a bit more, but overall, he was lethargic with his strike/constriction... In fact, when he finally got around to eating it, it was still just barely breathing.

Should I just chalk this up to him being in a new environment? Do younger BPs tend not to strike/feed as quickly as adults? Temps/humidity is near ideal (~95/85, 70%). I have only kept sub-adults and adult BPs, and they have always been amazing eaters for me--immediate and voracious. Excuse me if this is a rather newbie question; I did a short search but it did not return quite what I was looking for.
