The Little Alphabet Cats from the Letter A to the Letter Z, or simply the Little Cats, are the Cat in the Hat's twenty-six children introduced in The Cat in the Hat Comes Back. According to the text in the book, the Little Cats are all male.
They help him clean up spots and also keep on making messes with snow spots and need help, too. The last cat named Little Cat Z is so tiny yet so impossible see. This cat has the VOOM on his head and in his hat and it helps the Cat in the Hat and his Little Cats clean up the snow and it blows all the Little Cats back inside the Cat's hat.
The Little Cats are diminutive doppelgangers for the cat himself and act as his cheerful helpers. Each cat is successively smaller than his predecessor and is labeled alphabetically. Little Cats A, B, and C are the most prominent of the group, though other alphabetized cats have been seen on occasion. The most notable of the rest is Little Cat Z, who is the smallest of all and, in Wubbulous World, possesses a hipster quality while speaking in his own language referred to as Zee and the like. Little Cat Fleep, a character from that same show, appeared in the episode Talkin' with the Cat.
