My cat use to bring them into our bed ALIVE!
I woke up one night to feel her playing and jumping all over my bed, I knew that wasn't right in the middle of the night.
I flipped the light on and I saw a mouse run under the pillow where my son was sleeping ( he use to sneak into our bed in the middle of the night when he was little) so I started screaming that there was a mouse in the bed and my groggy husband was trying to catch it, so was the cat and I had grabbed my little guy and ran out of the room.
Another night, I woke up to hear blood curdling screams from the bedroom my girls share.
I was terrified, I could not imagine what was happening at 2:30 a.m. to make them scream that way.
So when I get upstairs they tell me, one daughter was sleeping but heard little squeaking that she thought was from our cat, so she called the cat up on the bed to snuggle and was patting it when she realized something was squeaking not meowing and yelled, the cat dropped the mouse onto my daughter's chest, she is screaming, my other daughter turns on the light , she starts screaming and the cat grabs the mouse, jumps off the bed and onto my other daughter who is sitting on the edge of her bed and drops it in her lap and it slid down her leg.
Now we are all running around trying to catch it, there was no way they would sleep with that thing still in the house.
Another time, we found one "dead" on the floor and my husband took it out and threw it over the fence, it landed in a snow bank.
When he went out later it was gone, and you could see the little imprint of its body.
There were no other marks in the snow where an animal might have gotten it, the mouse must have been playing dead or something and run off.
Oh the joys of cat ownership.
