The squirrel is balancing along the fence at the back of the gardens. Next door is a white cat with a pink collar, sitting on her shed roof. Looking from the window upstairs I can see their meeting coming, and wonder if I should open a window and shout out a warning to the squirrel, but it looks big enough to look after itself. It sees the cat just before the she sees it, and leaps easily onto a steep roof and climbs until it's up near the birds. The cat sits and looks greedily until she gets a crick in her neck.
