Story of a Mouse Part II

Part II:
In the middle of the night, I heard scrabbling around. And around. I would move in bed and the noise would stop. I figured that mouse was still in the house, and under my bed. All night. The next morning, after a biiiiig cup of coffee, I began moving my bed out from the wall in search of this elusive little creature. I cursed CURSED when I moved a newspaper and saw a cat "gift" that must have been left by our aged infirm feline. Except this moved. And I did a double-take. I was extremely freaked out when I realized I was looking at newborn mice.
To recap:
Cat catches mouse.
Alive mouse is carried in house by cat.
Mouse runs loose in my bedroom.
Mouse gives birth.
Human finds baby mice.
Human does not find mouse mom.
Baby mice are not cute.
