Hamsters - Shockingly, hamsters are banned in Hawaii. The Hawaiian Islands take strict measures to preserve their environment and local species, so they are wary of any pets that could have a negative impact if released.

Salamanders - Salamanders are the smiliest of lizards, but they're also known to carry salmonella. This bacterial infection can easily be passed to humans, so these little fellas have been banned in countries such as Singapore.

Bengal cats -

Bengal cats don't look that different from your average house cat, but they're actually a hybrid cross of a domestic cat and a small Asian leopard cat. There's a blanket ban on hybrid animals in a lot of places. In the US, owners are petitioning a change in the laws.

Sugar gliders -

Sugar gliders are the cute nocturnal cousins of the squirrel. But they're not the best pets. They require a lot of outdoor space, they make a lot of noise, and they may be a threat to local species. It can also be difficult to source their food.

Wolf dogs -

Wolf dogs are crossbreeds between domesticated canines and wolves, and still have a lot of wolf DNA. Some countries accept them the same way they would any other species of dog, but others find them too risky.

Quaker parrots -

Quaker parrots are native to many countries. But they're banned as pets in most places, as they may be invasive to the local animal population. Some US states allow them as pets, but with restrictions that seriously impact the bird's quality of life.

Hermit crabs - Hermit crabs are another strange animal banned in Hawaii. They didn't provide any reason for the law, but it's likely they're concerned about the possible impact on local species.

Fennec foxes -

These tiny adorable foxes are native to Africa. Naturally, their size and playful nature make them coveted pets, but their ownership is banned in several US states. As exotic imported animals, their physical and emotional needs may be impossible to meet in a domestic environment.

Indian star tortoises -

This rare and beautiful breed of tortoise is an endangered species, so it is protected under the Convention on International Trade in Endangered Species of Wild Fauna or Flora.

Bearded dragons - Some places have banned the importation of bearded dragons as pets because they have no natural prey in a new environment, and are likely to compete with the local species. They're also known to prey on birds and their eggs.

Servals -

The serval is one of the most beautiful exotic cats, and has become a desired pet for many cat lovers. They're commonly outlawed as pets because they are truly wild and struggle with domestic settings.

Slow lorises - These sweet-looking creatures are illegal to export from their native lands in Northeast India and Southeast Asia. It's legal to buy them in countries like Russia and Japan, but in most places you can't even find them in zoos.

Skunks -

It's surprising that it's even necessary to ban skunks as domestic pets, but some animal lovers have been domesticating them for more than 60 years.

Skunks -

It's necessary to have their scent glands removed as a baby to be able to keep them in the home. Nevertheless, they are a risky pet as there is currently no rabies vaccine for skunks.

Burmese pythons -

The Burmese python is a large exotic snake. They are illegal to keep as pets in many places, as they wreak havoc on the local species if released.

Capybaras - Capybaras are semi-aquatic rodents that can grow up to 140 pounds (64 kg). They do better with company, so you should have more than one capybara, lots of space, and lots of water for them to swim in. It's pretty hard to provide them with the right conditions!

Wallabies -

Wallabies are often referred to as "mini kangaroos" and are common in the wilds of Australia. They are sometimes imported to the US, but they are banned within cities as they require a large amount of space and special care.

Chimpanzees -

While they're adorable creatures, chimpanzees can grow up to 150 pounds (68 kg) and can have a lifespan of 50 years. That's a lifelong commitment, and they're not easy pets. They're banned in most places, as they really do belong in the wild.

Alligators -

This one is on the obvious side, but apparently it still needed to be said! Naturally, alligators are extremely dangerous and would require a very specific environment and care. It's possible to obtain a permit for an alligator in some US states, if you can prove you've got what it takes!

Penguins -

All species of penguin are heavily protected, so it's impossible to own them as pets, even though they adapt well to milder climates.

Gibbons -

These monkeys are usually cruelly captured by force. The entire family may be killed just to obtain one baby, which will be sold as a pet. This is one of many reasons gibbons aren't allowed as pets.

Bats -

Bats are a protected species in most of the US, so it's illegal to capture them from the wild. There's just not much sense in trying to have a pet bat.
