You could also put your baby bath in it with about an inch of water in it.
My cat started doing stuff like that when i stopped paying as much attention to him. I treated him like a baby and tried out the vibrating bouncenet on him (bad i know) and then when I was too exhausted to give him the same kind of attention he would do bad thngs.
The whole time I was in labour he sat next to me. When we came home from the hospital he was asleep in the cot

and I'm guessing its because i was gone for a few days.
