Hello Donna,
I see that you are new, so WELCOME!
All of my pets have had at least one strange behavior. I've always just thought that made them unique and more lovable. As an example, my 15 year old dog tries to sing when I pet him. With a cat, I think that Pastor Roger probably got close. It does sound reasonable to associate that behavior with some sort of cleaning. I would also be curious to know if the cat likes to be in the water.
I only had a cat once, and the cat didn't like me at all.

YES, I did try pretty hard to make friends with him, but I was just a nuisance.
I sincerely hope that you enjoy Christians Unite. I look forward to reading your posts and having fellowship with you.
Love In Christ,
Tom
