My edition is slightly different than the one described here. Instead of "Ten Lttle Kittens walking in a line; one plays with a feather, that leaves only nine." ; mine starts out on the cover with "Ten cuddly little cats together all the time. But one strays off alone and then there are nine." It is a Brimax Book, published in 1971, though.
My daughter and I loved this Board Book brimming with cats on its tabbed pages.
