Slippers are preferable to bears.

Last night, Kittencat came into my bed at something o'clock in the morning. I ducked to the loo briefly, and gave her a bear to cuddle while I was gone. She was content and cuddling the bear, and when I came back, she said, "You can have your slipper back now". On learning it was a bear, and not in fact a slipper, Kittencat became distraught, and I got quite a stern telling off about the whole affair. Kittencat is quite strict about bears.
