The Princess and the Pets — Angela Kanter

Princess Mina longs for a pet, but her sister, Princess Tina, is allergic to animals. When Princess Mina texts a birthday wish to her absent-minded fairy godmother, she gets more than she bargains for. In a blink of an eye there are kittens in the kitchen, puppies in the parlor, and a boa constrictor under the bed! Mina and her fairy godmother will have to act quickly to get this pet situation under control.
