Top 10 Worst Animals to Have as a Pet

The Top Ten
1 Skunks Skunks are mammals known for their ability to spray a liquid with a strong odor. Different species of skunk vary in appearance from black-and-white to brown or cream colored, but all have warning coloration.

I believe they are cool animals, but if you really liked them, you'd let them live happily in the wild.

They would be cool pets, but your whole house would stink, and no guests would come for a fancy dinner party.

Skunks are bad smelling and the worst pet to have. I am happy this is number one.

2 Sharks Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays. However,... read more

Yeah, I agree with those who love sharks. But as a pet? I'm not a huge "look but don't touch pet" fan. I'm all in for exotic pets that can be tamed easily. A shark, for instance, is not a hands-on pet.

For starters, they can fatally bite, and they're aquatic. Plus, they're not meant to be housed in a somewhat small enclosure. They belong in their natural habitat - the wild! That's how God designed them.

No matter how much you LOVE them, they don't make good pets. As Wild Kratts would put it, "Living free and in the wild!" lol.

3 Dogs The dog or domestic dog (Canis familiaris or Canis lupus familiaris) is a domesticated descendant of the wolf, and is characterized by an upturning tail. The dog is derived from an ancient, extinct wolf, and the modern wolf is the dog's nearest living relative. The dog was the first species to be domesticated,... read more

I hate dogs. They bark at everything, slobber all over you, jump on you every time you enter the house, smell REALLY bad, and they lick your face and, worse, your MOUTH. Seriously, who likes that? That's disgusting!

They're WAY too overrated, but the owners are the worst of all. They'll do strange things with these animals, like try to mimic their behaviors. They'll bark at them and think they're "communicating with them," and some owners don't even care that their mangy mutts kill people.

I mean, seriously, someone in my neighborhood had their dog shot by the police because it was out of control and they said they were "only trying to play." It's super creepy.

4 Lions The lion (Panthera leo) is a large cat of the genus Panthera native to Africa and India. It has a muscular, broad-chested body, short, rounded head, round ears, and a hairy tuft at the end of its tail. It is sexually dimorphic; adult male lions are larger than females and have a prominent mane. It is... read more

They'll kill you and probably not even eat the corpse. Lions are very wasteful.

They'll kill you. How is this lower than perfectly normal animals?

Where the heck are you gonna get one of these? The black market?

5 Elephants Elephants are the largest existing land animals. Three living species are currently recognised: the African bush elephant, the African forest elephant, and the Asian elephant. They are the only surviving members of the family Elephantidae and the order Proboscidea, extinct relatives include mammoths... read more

Elephants are great animals, but who would want to keep one? Absurd! The survival rate would be 36% for the human. By the way, why are dogs ranked higher than elephants? They should go down to, like, 126th.

Elephants need to be left alone. Many people kill them just for their tusks, for the ivory black market trade. Leave these gentle beasts alone.

They are illegal to keep. Who would even want one of these in their house? They are huge, and they belong in the wild.

6 Tigers

The survival chance for a human with a tiger is 30 percent. Who in their right mind would have a tiger as a pet? According to me, a tiger would be the worst pet to have.

In other words, I saw dogs up there at #11, and I think you should demote dogs to like #452. They are the best pets.

This is awful for the person and the cat. It is dangerous for the person and absolutely depressing for the cat. Would you want to live in a metal box your whole life? God, no! Leave them in the jungle and stop cutting down the forest. We will all be just fine.

7 Cats The cat (Felis catus) is a domestic species of small carnivorous mammal.
It is the only domesticated species in the family Felidae and is often referred to as the domestic cat to distinguish it from the wild members of the family. A cat can either be a house cat, a farm cat or a feral cat; the latter... read more

They are the worst pets to ever have! Dogs have been domesticated way longer than cats (well, maybe not, but I like to say that). They are mean and vicious little things. Their relatives are way scarier than dogs' relatives. They bite more than dogs and look a lot more intimidating.

They come in only two different shapes and very few different colors, while there are a ton of different dog breeds. All they want is food, not your love and friendship. They don't look up to you for anything but food and are more likely to run away than dogs.

This is only my opinion. Your opinion counts too, so you can dislike or like my comment. I only spoke because I wanted to say something. Honestly, I didn't need to say it.

8 Blue Ringed Octopus The Blue Ringed Octopuses (Hapalochlaena) are the four strongly venomous species that are found on the coral reefs and tidal pools in the Pacific and Indian Ocean, particularly from Australia to Japan. It is known as one of the most poisonous and deadliest sea creatures. It can kill a human body by... read more

Enough venom to kill something like 16 adult men! They have them at my local store and on a website called discountfish.co.uk in the marine section. You must be crazy to get one of these bad boys.

9 Rhinoceros A rhinoceros, commonly abbreviated to rhino, is a member of any of the five extant species (or numerous extinct species) of odd-toed ungulates in the family Rhinocerotidae. (It can also refer to a member of any of the extinct species of the superfamily Rhinocerotoidea.) Two of the extant species are... read more

How do you keep a rhino as a pet? It's too big! It only belongs in zoos (as long as the zoos are humane and up-to-date) and in the wild.

Wild animals belong in the wild.

You can't keep any of these animals besides cats, dogs, and raccoons.

10 Birds

Loud, obnoxious, dirty. Their feather dust gives people respiratory infections, and their feces have hordes of dangerous bacteria and viruses. Did I mention that they NEVER SHUT UP and are very messy?

How can a 'symbol of freedom' be a pet, a prisoner? They're nice animals and fun to watch, but locking them up for just childlike desires is merciless.

Birds are definitely the worst pets! They squawk all the time and have nothing good about them.

The Contenders
11 Lizards

They will kill each other, not to mention you. They are very poisonous. You are better off with another lizard that is not so dangerous. Why would you want one?

If you love wild animals, I guarantee you would want them to be happy, which means leaving them in the wild because they are wild animals.

They are boring. Fish swim, but lizards just sit still as a rock!

12 Raccoons The raccoon, sometimes spelled racoon, also known as the common raccoon, North American raccoon, northern raccoon and colloquially as coon, is a medium-sized mammal native to North America.

A raccoon almost bit my hand off trying to steal my sandwich.

They killed over 12 chickens, and one rabid one killed my cat.

13 Alligators An alligator is a crocodilian in the genus Alligator of the family Alligatoridae. The two living species are the American alligator and the Chinese alligator. Additionally, several extinct species of alligator are known from fossil remains. Alligators have long existed since the Oligocene epoch 37 million... read more

An alligator is dangerous. You can't provide a good habitat for one, and it could eat you.

They can grow up to 6 feet long, and they are pretty dangerous!

You wouldn't live very long after that.

14 Monkeys Monkeys are haplorhine primates, a paraphyletic group generally possessing tails and consisting of approximately 260 known living species.

Cute, but should never be kept as pets. I'm going to be honest, monkeys are a lot like humans and deserve the same amount of attention and care as a baby does, except for a lifetime.

Most people don't have that kind of money and time to devote the proper care it takes to take care of a monkey. Plus, they live as long as humans. It's very abusive to treat a monkey as a pet because they are almost human. It's very slave-like and degrading to treat them as pets when they are so much more.

They are unpredictable wild animals. Probably harder to take care of than eight toddlers at a time. They can maim and kill you if they are mad.

15 Fish

WHY ISN'T THIS NUMBER 1?

They have a really short lifespan. I used to have a bunch of them when I was little (I'm Asian), and they all died within 1-2 weeks of being purchased. They are also very boring.

They don't do much and you can't actually do anything with them. Asian people mainly treat them more as house decorations than actual pets.

Who wants to just sit there and watch a little orange thing move around a small bowl all day? The fish are also sad in that cramped little space. Let them roam free in the ocean.

16 Tasmanian Devils The Tasmanian devil is a carnivorous marsupial native to the island of Tasmania in Australia. It is characterized by its stocky build, black fur, and powerful jaws. Tasmanian devils are known for their fierce temperament and distinctive vocalizations that include screeches and growls. They have a strong... read more

Who keeps this species as a pet? It has a strong jaw with sharp teeth and sharp claws on its front limbs. This animal can be really aggressive in captivity, so it is a big no-no for a pet.

I heard of a woman who had a cat and a Tasmanian Devil. After a day, she had a skeleton and a Tasmanian Devil.

They'll spin like tornadoes if you have one.

17 Hippos The common hippopotamus, or hippo, is a large, mostly herbivorous mammal in sub-Saharan Africa, and one of only two extant species in the family Hippopotamidae, the other being the pygmy hippopotamus.
18 Snakes Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears.

Snakes should NOT be considered pets, let alone good pets. Snakes are very important animals functioning in their native habitats and should be admired. A picture on the wall or a video of a snake is a more logical choice than a living snake in an enclosure that someone considers their "pet."

No, snakes are not meant to be pets. In the name of keeping an "exotic" animal as a pet, we are actually harming these poor creatures that are meant to be in the wild. So, nope, snakes are not good pets.

Snakes are ugly and dangerous. I hate that some people feed innocent puppies and kittens to these poisonous monsters.

19 Wolves The wolf (Canis lupus), also known as the gray or grey wolf, is a large canine native to Eurasia and North America. Over thirty subspecies of Canis lupus have been recognized, with gray wolves comprising the wild subspecies. As the largest extant member of the Canidae family, the wolf is distinguished... read more

Wolves are wild animals, but they can be kept as pets. They can act aggressively towards younger children and smaller pets, and they have a nasty bite. They poop all over your house and are illegal. How's that for a pet, wolfaboos?

They would eat you or just eat a hole in your wallet due to how ridiculously expensive they would be. Really, they would just be a highly dangerous and expensive "pet."

Wolf-dog mixes have become too popular. They are not afraid of people and are known to attack them. Wolves are more scared of us than we are of them.

20 Hyenas Hyenas or hyaenas are any feliform carnivoran mammals of the family Hyaenidae /haɪˈɛnᵻdiː/. With only four extant species, it is the fifth-smallest biological family in the Carnivora, and one of the smallest in the class Mammalia.
21 Whales

Only possible (and plausible) if you owned enough real estate to sustain a pet whale enclosure.

22 Ferrets The ferret is the domesticated form of the European polecat, a mammal belonging to the same genus as the weasel, Mustela of the family Mustelidae.

Ferrets are my least favorite pets in the world. Getting ferrets was the worst thing that ever happened to my family. Ever since we got them, the annoying ferrets have destroyed everything they saw and bit everyone. Of course, all my family members loved them except me.

Whenever one of our four other pets even growled at a ferret, they got locked in a room, and I get locked in a room whenever I say something bad about ferrets. They are my least favorite pets!

At first, I wanted a ferret, but when my friend said her hamster was suddenly aggressive, I couldn't imagine what a ferret could've done. Now, I really want one because they're so cute!

23 Giraffes The giraffe is a tall African hoofed mammal belonging to the genus Giraffa. It is the tallest living terrestrial animal and the largest ruminant- hoofed herbivorous- on Earth. Traditionally, giraffes were thought to be one species, Giraffa camelopardalis, with nine subspecies. Most recently, researchers... read more

You need a big house for that!

24 Spiders

Spiders are cool, but some are bad pets like black widows and brown recluses, and those deadly spiders. I like spiders like tarantulas. They are cool. I have always wanted one!

25 Crocodiles Crocodiles (family Crocodylidae) or true crocodiles are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia. The term crocodile is sometimes used even more loosely to include all extant members of the order Crocodilia, which includes the alligators... read more

Seriously? If you think this is bad, just look at humans. Humans are the top predator. And it's not like you would sleep with it or anything. It would be cool to watch. I know this personally.

This image just sums up how dangerous they are!
