Weird feeding behavior?

[regi375]

Last week when I fed my ball python Fiona she did something a little odd. Moved her into the feeding tub so she could eat. I was feeding her a live mouse since that's what the pet shop had her on (want to get her eating good before I switch to f/t). She immediately bite the mouse and began constricting it, but once it was dead she just left it there. I was wondering if this common? I was supervising her as she ate so I'm not sure if I was the cause. Once she lost interest though I placed the dead mouse in her hide on a paper towel, and put her back into the enclosure. The next morning when I checked it was gone and she was on her basking spot. Just thought it was something strange enough for me to post about it. Hopefully she'll actually eat the mouse when she kills it on Sunday :P
