Our cat is an indoor only cat.
At night, as we are going to bed, we can hear you tearing around downstairs. She meows. She races all over the place. Then she come up to the bedroom flops on the bed, and calls it a night.
When we wake up in the morning and go downstairs, there is always one of her stuffed toys - usually the stuffed mouse - sitting at the bottom of stairs.
I imagine she is down there, hunting up a storm, while Mrs. NoWhammies and I are getting ready for bed.
