Veterinarian Daantje and the animal ambulance

It's busy at Daantje's father's animal clinic. Between all the sick and injured animals, the vet is looking for an assistant and an extension is being built with new cages for animals that have to stay overnight. Daantje tries to get in her father's way as little as possible, but that's quite difficult when there's nothing to find! Fortunately, there has recently been an animal ambulance in the region that works a lot with Daantje's father, and Daantje and her best friend Tofu are regularly allowed to go out with the friendly driver Karel. For example, they save a hedgehog from a dire situation and get an injured cat off a roof.
When that cat is then stolen from the animal clinic, Daantje, Tofu and Pluis immediately start investigating. Will they be able to find the culprit?
