Kitty has always thought she was allergic to cats, but during a midnight sneezing fit at a sleepover, she learns that the truth is far more magical—Kitty is able to turn into a cat! She eagerly takes her place as the Guardian of the local cats' Cat Council, using her human knowledge to help them solve their feline problems.
Coco is upset when her owner, Evie, brings home Ruby, a playful Bengal kitten. Coco isn't getting nearly as much attention as her new housemate and makes Ruby feel very unwelcome. Now Ruby has run away and Evie is very worried. Can Kitty lead the Cat Council to find the lost kitten?
