This is Jazz, after an infusion of catnip. Cats, if they like it and not all cats do, are drawn to it, eat a bit then lie down and roll in it. Sort of a contact high, I guess. Eventually they go into this semi-catatonic state until it wears off.
Now Jazz and Blackwell don't get along. Normally, all the big black cat has to do is look at Jazz and she begans to hiss and snarl. On this day, he came over and, typically, sat down about 18 inches away, seemingly just to irritate her.
Jazz scowled at him but that was about all.
When Blackwell got bored and headed for his food bowl, Jazz relaxed once again into her catnip haze.
