THE following facts are curious: I should be glad if any of your readers can inform me whether anything of the kind has been already noticed. I have a cat of half-Persian breed; she is about eight years old, and has always been remarkable for her aversion to strangers, more especially to children. If children have at any time come into the house where she was, she has invariably decamped and secreted herself. She never could bear to be handled or pulled about (which so many cats seem to enjoy) by anyone but by her master.
