Nice. Never saw a cat fetch before. My favorite cat was Maggie---a black cat that had a huge thumb--not just 6 toes, but a thumb. My son said he saw her sitting in the yard one day, gripping and eating a french fry---like a person with her opposable thumb making it possible! She died. Miss her a lot.
When you look into their eyes and you blink,and you try to get them to blink back...Sometimes they seem to.
They, or some, will yawn and look away for a few seconds if you start talking to them, especially if you don't know them. Kind of like--well--I may pay attention to you--then again I may not. But they usually do. I guess it's a way for them to gain a little time to figure out if they're going to trust you or not.
