Require background checks before customers can purchase an animal

People are buying pets without having the necessities and it leaves the animal in a depressed situation e.g. buying a pet bird but keeping it in a tiny small cage, buying a hamster and keeping it in a tiny small cage, buying a dog without having a field nearby or open garden space, buying any animal and not being able to afford emergency vet bills. These are all basic needs for an animal and you should be examined on what you can afford and making sure you provide a pet with a good environment.
