Our dearly-departed kittie Sarah would catch birds and bring them into Tommy's room (her room, too), but she'd devour them such that all that was left on the carpet was a few feathers, a beak and the feet. She was neat, too- no blood.
Snakes, on the other hand, were to be brought in, still writhing and fighting, while Sarah strolled along proudly showing-off her conquest. She'd really get ****ed when I took the snake away from her and put it back in the yard, there to resume bug-eating detail (or to slither off to die from the injuries visited upon her by SarahCat).
It was really tough when she carried in three baby bunnies, still alive but too far gone to save (and we had no idea where the mom was anyway).
