Dear Zoo

One of Luigi's favorite books and one that I enjoy reading is "Dear Zoo" by Rod Campbell. If you're not familiar with this nearly 40 year old book, here it is:

Presumably, a child asks the zoo for a pet, and the zoo sends multiple animals not suitable for a residential environment to the kid. While it's a fun book (and yes I know this is fiction), there are several questions here:

* Who at the zoo is just sending an elephant or a lion to a home? Do they just have extra animals around that they can't fit in their space? 

* Was there any vetting at all done here? How is this kid going to take care of a giraffe? Does he/she have a proper living environment and food for a giraffe?

* What type of zoo has dogs? That seems like a boring exhibit when you can just go to a dog park for free.

* Who is paying for the back-and-forth shipping? Sure, it probably doesn't cost much to transport a frog or snake or even a camel, but I can't imagine that it's cheap to move an elephant!

I feel like this zoo is not going to be in good standing with the Association of Zoos & Aquariums!
