Totally agree, that is one unhappy kitty. The breed must be very good natured, because with the level of agitation that one is displaying I would have expected it to disembowel that child by now.
Daveroo, my (ex) in laws used to have an oriental spotted tabby, which is basically a siamese wearing a tabby coat. Like most oriental cats Basil had oodles of personality; my father in law used to take him out for dog-type walks but didn't nead the lead, the damn cat would walk to heel - they lived on a cul de sac, so I guess it was safer than your situation!! We worked under the assumption Basil thoiught he was part dog anyway; his best mate was the Golden Retriever next door, first thing he would do when let out in the morning was run next door and yowl for Harry to come out to play - the sight of the two animals playing used to stop passers by dead in their tracks, a dog & a cat rolling around on the grass together.
