18 Exotic Animals People Shouldn’t Be Keeping as Pets—Yet 17.6 Million are in U.S. Homes

The rising popularity of exotic pets comes with hidden dangers. Recent studies estimate that 75% of emerging infectious diseases are zoonotic, with many originating from exotic and wildlife species.

The CDC reports that approximately 6 out of every 10 known infectious diseases in humans can be spread from animals.¹ As human populations expand and encroach on wildlife habitats, the risk of zoonotic disease transmission increases.

The exotic pet trade, valued at billions of dollars annually, further complicates this issue. In 2020, a survey by the World Animal Protection non-profit uncovered that there are about 17.6 million exotic pets spread across 9 million households in America (mostly birds and reptiles²).

So, before you make a decision you might regret, here are 18 exotic animals that should never be kept as pets.

1. Hyacinth Macaws
