Smoke Cat - Newbery, Linda

Every day Simon sees mysterious and magical soft shadowy cats of every shape and colour in next door's garden, There they twine themselves around the ankles of a strange old lady. But there's one cat, smoky-coloured, named Blue, who won't go to her, no matter how much she calls his name.
