Well today was a real cracker of a day. A while back, after I made that post, I decided to try the warming trick. At first I thought this wasn't going to work as the rodent would cool down too quickly and return to room temperature within a few seconds, but I tried anyway and got a real surprise. She was underneath her hiding spot, as usual. I usually just leave the rodent to thaw on a bench and then offer it once it's soft. But this time I defrosted into a cup of very warm water, let it sit for 5 minutes, and then when it was still very warm I gently vibrated it against her neck, and within about 30 seconds she was completely wrapped around the rodent, jaws and all. I had no idea they had such a strong preference for warm prey items, but I guess that because they have warm prey items in the wild this would make perfect sense.
I used to assume that they will just take thawed rodents, regardless of whether the rodent is warm or not...but I was wrong. I'm going to be offering warm prey from now on. I am beginning to think this is critical to an RSP's feeding response.
