For those of you who feed f/t prey, does your snake still constrict, or just slither up to it and start swallowing it?

I just fed my bp again, her 4th f/t meal (woot! woot!). Each time she's constricted it after a nice rat jig, but this time the movement seemed to scare her away. So i just left it on the floor of the box. Sure enough, she goes up to it and sora does this half@ss constricting display- she just grabbed it and held on to it for a second before she then proceeded to swallow it. Very wierd.

So is anyone else's bp as lazy as mine is?
