That mrrrrt? sound is one of my favorites!!! My Alabama does it whenever I touch her while she is sleeping..something I do often just to elicit the sound..he he he..so what, she has ALL day to sleep. I have the cat bed in the window in my bedroom, and the drapes wouldn't close or stay closed. I now babypin the things shut every night!! The cats now have a little teepee, and I don't get the neigbors porch light directly in my eye..all is well.
