Are you looking forward to building a zoo in your backyard?Then you have reached the right spot. The first hurdle would be the law of keeping zoos. Most states of USA are not governed by laws or permits for raising backyard zoos.
Soem states do have a restriction and it is best to check if your state is one among them. The next step would be to buy exotic wild animals for your zoo. They can be easily sourced through online auctions.
One word of caution is that it is always better to know the cons of owning wild animals in residential zones. Take necessary precautions for the safety of the animal and the humans around in case of a mishap.
