SAS you have good reason to worry about live (or once live prey) in your bed or elsewhere. I once had a big beautiful tabby boy who put a dead pigeon on the pillow next to me while I was sleeping. I was groping around in the dark to turn on the light and put my hand on the dead bird. The blood curding yell was heard by all my neighbours. After disposing of the bird and locking the cat out of the bedroom for the night next morning I opened the door and stepped on another dead pigeon that he left outside just outside the door.

I also had another very intelligent black female cat who put a dead mouse in my shoe after she tried to get my attention to show me her hunting skills and I just ignored her chirupps. In the early morning I slipped my shoes on and felt something in my shoe....
yup the dead mouse. I threw those shoes out immediatley.

So all in all the Abys have been pretty good . They only bring toy mice and garbage to the bed.
