Weird things your cat does?

My little Bengal Phoebe constantly needs attention. One thing I used to be able to do with her to get her to keep herself entertained was to run the bath water. When I turned it off, she would stare at the drain for almost 1/2 hour. She does not do that anymore. She also likes to watch the toilet flush and drain. My wife and I are very careful now to keep the toilet seat completely shut. I don't want her falling in there.
