25 Amazing Animals that Are Illegal to Own as Pets in The US: Forbidden Companions

Illegal Animals to Own as Pets in America

Ever find yourself daydreaming of living out your Disney fantasy, walking arm in arm with a squirrelly sidekick or taming a pet tiger as your own personal Rajah? It’s a charming notion, albeit one that might need to be shelved in favor of more traditional domestic companions, like the faithful canine or the independent feline.

The intricacies of pet ownership in the United States are not straightforward. There are creatures out there whose companionship comes with a significant caveat: illegality. What’s intriguing, though, is that few animals are universally proscribed. Rather, the parameters of legality are state-defined, sketching a fascinating patchwork of pet policies across the nation.

At the top of the no-pet list are, predictably, the large and explicitly dangerous animals. The mighty bear, the formidable big cat, the venomous snakes, and the spiders are all widely prohibited. But it’s not just about size or venom.

Cities, for example, may ban certain animals due to their spatial constraints. In some cases, the concern is a disease, as certain pets can carry afflictions such as Salmonella or Ringworm. In others, the animal may simply be ill-suited to a state’s particular environment.


Let’s take gerbils as an illustration. These endearing rodents, while welcome in most American households, face a statewide embargo in Hawaii and California. The concern here is not danger but ecology. The natural desert habitat of these states could empower a few fugitive gerbils to multiply into an invasive scourge.

Likewise, ferrets, potential carriers of rabies, are restricted in numerous cities. Some states do, however, allow them under the provision of vaccination or special permits.

However, the most heartbreaking side of this tale lies in the recurring stories of underestimated wildness. Exotic animals, despite our best efforts, often retain a fierce core of untamed instinct that can lead to tragedy. The story of Travis the chimpanzee, who brutally mauled a family friend in 2009 after a lifetime of peaceful cohabitation, is a chilling reminder of this. And just last March, a legally owned pet zebra in Ohio turned on its owner.

Despite some dog breeds, such as German Shepherds or Siberian Huskies, boasting about their genetic affinity to wolves, pure wolves are forbidden as pets in the U.S. This is largely due to their undomesticable nature. Wolves are often shrewd enough to escape from captivity and exhibit unpredictable and sometimes aggressive behavior.

It’s quite apparent that lions, with their inherent predatory instincts, size, and power, are unsuitable as pets. Recently, President Biden signed the Big Cat Public Safety Act into law, prohibiting private ownership of lions and other big cats nationwide. Existing lion owners were given 180 days to register their pets with the U.S. Fish and Wildlife Service or face severe penalties or imprisonment.

Ownership of a primate as a pet largely depends on its category—monkey or ape. Nine monkey breeds are typically kept as pets: tarsiers, tamarins, chimpanzees, squirrel monkeys, macaques, capuchins, marmosets, spider monkeys, and guenons. Regardless of the breed, primates are generally unsuitable pets, owing to their high energy levels and the need for spacious environments and social interaction. Some states have varying laws regarding primate ownership.

Despite their small size and cuteness, squirrels are best left in the wild. Pet squirrel ownership is illegal in 26 states across the U.S., including Alaska, New Hampshire, Alabama, and Wisconsin. Their requirement for a lot of outdoor space and their sharp claws that can cause destruction make them unsuitable for captivity.

Raccoons are notoriously known for their unpredictable behavior and ability to break into secured places. They can become aggressive and attack with little notice, even if they spend considerable time with humans. Therefore, pet raccoon ownership is prohibited except in a few states.

Sugar gliders

Sugar gliders, tiny relatives of the kangaroo, have gained popularity as exotic pets due to their adorable appearance and playful gliding ability.

This extremely rare three-foot-long fish can cost upwards of $150,000 when bought abroad. This is partially due to its cultural significance in Asia as a symbol of good luck. However, it is illegal to own an Asian arowana in the U.S., due to its status as critically endangered.


Mini pigs are gaining popularity as household pets—but unfortunately, there isn’t such a thing as a “mini” pig. “Teacup” and “micro” pigs are just undernourished piglets that will eventually grow over 100 pounds, with some even exceeding 500 pounds. Furthermore, many adults can become aggressive toward humans. Many cities prohibit keeping farm animals within city borders, a rule that many pig owners don’t realize until it’s too late.
