Bats are one of those animals that should never leave their habitat to be household pets. They require specific care, which makes them complicated animals. If they stay away from forests or are taken away from their group, then they feel terrible loneliness. Also, family members can get infected with viruses like rabies or SARS, which these bats carry.

Tigers as pets sound like a bad idea. Their instincts can harm or even kill family members. They can be trained at a very young age, but they never tend to lose their wild instincts. Besides the cruelty, owners lack certain resources needed for tigers, like proper food, housing, or even medical attention.

These venomous reptiles are not a good fit for pets. They can cause internal hemorrhaging or even damage our skin tissue permanently with just one bite. Even after good care, there is always a chance that this snake can try to kill other pets in the household or family members, especially kids.

This Australian marsupial looks almost similar to a kangaroo. They are considered expensive pets because they need a lot of space and natural exposure. When they are left unsupervised, they tend to damage the property. Moreover, if they come close enough to a cat, then wallaroos can die due to the toxoplasmosis parasite in cats.

Before keeping a chimpanzee as a pet, you should be aware of their incredible strength, which increases over time. They are unpredictable and smart animals with behavioral patterns, which makes them challenging to manage. During sexual maturity, they get more aggressive towards other animals. With just a few bites, they can spread parasites like ringworm or the Ebola virus.

Raccoons are nocturnal animals with unpredictable behavioral patterns. Even with intensive training, they do not understand basic commands. They must be kept away from kids, as they can cause damage to them by poking fingers in their eyes or twisting their hands. They act strange when sad and may cause disturbance in the house by peeing everywhere.

Many people like scorpions as their pets because they find them cool and fascinating. However, scorpions can prove to be deadly animals due to their venom-producing abilities. Scorpions are considered observable pets; you cannot usually interact with or handle them due to the fear of getting stung.

Wolfdogs look like domestic dogs, but they have instincts like gray wolves. They can get aggressive when confined and they are almost impossible to train. Despite being smart animals, they tend to refuse basic commands like staying and standing. They see the kids as their prey and are likely to kill or harm them.

Having a crocodile as a pet might sound expensive. They are short-tempered animals and hard to maintain. With an instinct to whip their powerful tail, they can damage furniture or even break someone’s leg. They have a bite force of around 1500 pounds, which is considered good enough to kill a person or any other animal.

Capybaras are rodents with teeth similar to those of a beaver. They get aggressive or show tantrums when kept in captivity. This is because they live in herds. So, if you are looking forward to having capybaras as pets, then you should at least have other pets. They may seem cute to many people, but they are quite high-maintenance.

In recent years, many people have preferred owning a skunk as a pet in their house. But they are not ideal pets because they have huge scent glands, which leave a strong, musky smell. They are not smart enough and lack homing instincts, which causes them to get lost if they escape from the house. 

Squirrel Monkey

Squirrel monkeys are mischievous animals that are hard to control. Undeniably, they are adorable animals, but they have huge tantrums, just like toddlers. Due to their small size, they require a lot of attention. Moreover, some of them also transmit Hepatitis A or HIV-1 when they bite someone.

Ostriches are usually raised on a livestock farm. It is quite difficult to keep them indoors as pets because they are not friendly birds and usually show bad tempers. Strong legs can easily cause severe damage to someone with a powerful kick. They prefer to live with their flock and become aggressive if kept with other animals.

Prairie Dog

Prairie dogs are usually mistaken for rodents due to their sharp teeth. They are active and playful animals, which makes them adorable pets. However, one must keep this in mind before owning them as pets: they get depressed if they do not socialize with other pets. Also, they are prone to obesity when kept in captivity.

Sloths seem like lazy animals, but they are quite dangerous if they use their sharp teeth or strong claws. They are considered high-maintenance animals due to their strong stomachs. They require a special diet; otherwise, they get sick or annoyed. They cannot live inside the house as they get stressed out in captivity.

South American Coatis are a crossbreed between a raccoon, a monkey, and an anteater. Unlike a raccoon, they do not have any musky smell around them. However, they are more aggressive than raccoons, especially when it comes to the age of sexual maturity. Due to their stubbornness and mischievous behavior, they require special care and attention.

Red-Tailed Boa is usually not aggressive but can show wild instincts if not handled with care. They cause serious injuries to someone sleeping as they can strangle or squeeze that person. For this reason, they cannot be trusted by other pets or kids in the house. Moreover, they get bigger every year, which means they need bigger places to fit in. 

Box Turtles

Box turtles are usually calm animals, but they tend to die from anxiety or stress when kept in captivity. For survival, they require big ponds and a well-balanced, special diet. Usually, box turtles carry salmonella, which is a disease that can damage the immune systems of elderly people in the house.

Iguanas can be considered observable pets because they are fascinating to look at from a distance but are likely to bite if interacted with. Hormonal changes make them more aggressive and behave differently during the breeding season. Moreover, with their spiky tails and sharp claws, they may harm family members.

Southern Tamandua are considered expensive pets because their maintenance cost usually lies between $4,000 and $8,000 per year. They show affection towards their owners, but they are not friendly with other pets around them, and their sharp claws cause damage to them. They also spray a bad scent from the anal glands to mark their territory.
