Dogs, hamsters, goldfish, cats, and reptiles, leave them in our hands, they will be safe!

Polly and Frida love animals and urgently need money. The ad they randomly see in front of them is the perfect opportunity: a lady is looking for someone to take care of her cat during the holidays. Polly and Frida immediately create the Pet Babysitter Agency and offer their services to the neighborhood.

However, this job proves to be more difficult than they expected: the cat Chrysoulina escapes almost immediately, the rabbit Herbert has a big surprise in store for them, and no one knows what kind of animal this mysterious and dangerous creature with the big claws is.

With lots of advice on proper pet care and suggestions for having fun with them!
