My Sidney has some similar quirks. If I'm in the kitchen, he will patiently sit by his dry food and wait for me to come over and top it off. Sometimes I just have to pick it up, shake it, and set it down again, and then he will eat it.

He also loves to be in the bathroom when I take my morning shower so that he can get attention. He doesn't allow any other cats into the bathroom because it is his time to spend with me. He'll then wait until I'm done with my shower so that he can get more attention.

When I pet him, he makes the most wonderful trilling noise - sort of a purr combined with a meow.
