Determining the rarest type of pet is not straightforward, as there are many factors to consider. The rarity of a pet is often tied to how exotic or unusual it is. Some of the rarest pets kept today include:
Exotic Mammals
Certain exotic mammals like sugar gliders, kinkajous, and capybaras are not commonly kept as pets. These unusual mammals have very specific care requirements and may be illegal to own without permits in some areas. This makes them quite rare as personal pets.
Sugar Gliders
Sugar gliders are small, nocturnal marsupials native to Australia, Indonesia, and New Guinea. They are closely related to opossums and kangaroos. Sugar gliders get their name from their preference for sugary foods like sap and nectar, and their ability to glide between trees using a stretchy membrane of skin between their front and back limbs.
As pets, sugar gliders are often described as a cross between a cat, squirrel, and bat. They are playful, social animals that bond strongly to their owners. However, they have very specific environmental and dietary needs. Sugar gliders are omnivores that require fresh fruits and vegetables, insects, and a calcium supplement. They are also highly social and must be kept in pairs or groups.
The exotic nature of sugar gliders, paired with the specialized care they require, makes them a rare pet that only dedicated owners are likely to keep successfully.
Kinkajous
Kinkajous are rainforest-dwelling mammals native to Central and South America. They are related to raccoons and coatis. With their slender bodies, prehensile tails, and grasping hands, they adapted to life in the treetops. Kinkajous primarily eat fruit, but also enjoy insects, small vertebrates, honey, and nectar.
Kinkajous are sometimes kept as pets, but they are not as common as cats or dogs. They tend to be high energy animals that require lots of space and enrichment. Kinkajous are nocturnal and can be quite vocal at night. They also require a specialized diet and certain permits to own legally. These factors make them a challenging and uncommon exotic pet.
Capybaras
Capybaras are giant rodents native to South America. They are semi-aquatic and live along rivers, ponds, marshes, and swamps. As the world’s largest rodent, they can reach sizes over 100 pounds. Capybaras are herd animals that live in large family groups in the wild.
The size and complex social needs of capybaras make them uncommon as pets. They require access to water for swimming and lots of space to roam. Legal ownership also requires permits in many areas. Some dedicated exotic pet owners are willing to provide the specialized care and facilities capybaras need, but they remain rare pets overall.
Exotic Birds
Some of the rarest pet birds include exotic parrot species and softbills that are not commonly kept or bred in captivity.
Hyacinth Macaws
Hyacinth macaws are the largest parrot in the world. They are native to central and eastern South America. Their brilliant blue plumage makes them a highly desirable and rare pet bird. However, hyacinth macaws are endangered in the wild and command extremely high prices as pets.
Providing for the extensive space, nutrition, and socialization needs of hyacinth macaws poses challenges for owners. These parrots are also very loud and destructive when bored or stressed. The rarity of this endangered species coupled with the expertise required to care for them puts hyacinth macaws among the rarest pet birds.
Palm Cockatoos
Palm cockatoos are large, distinctive parrots endemic to New Guinea and some Indonesian islands. They have an exceptionally long lifespan compared to other birds, sometimes living 60 years or more. Palm cockatoos have a very limited range in the wild and are threatened by habitat loss. This makes them uncommon in captivity.
These parrots require a huge aviary and specialized nutrition including fresh seeds, nuts, and fruits. Their loud vocalizations may make them unsuitable for suburban areas. Very few breeders work with palm cockatoos, contributing to their rarity as pets.
Superb Lyrebirds
Superb lyrebirds are not parrots but unique songbirds native to Australia. The males have gorgeous, fanned tail feathers. They are incredibly skillful mimics and their wild songs incorporate sounds from their environment. Superb lyrebirds are not well established in aviculture due to their specialized needs.
In captivity, they require a naturalistic aviary with plenty of space to roam and substrates to scratch through. They have a specialized diet heavy on insects, fruits, and fungi. Their rarity among private breeders and lack of captive-bred pet birds makes superb lyrebirds extremely uncommon companion parrots.
Exotic Reptiles
Many exotic reptile species are rarely kept as pets due to legal restrictions, difficulty breeding in captivity, or very specific care requirements.
Reticulated Pythons
Reticulated pythons are the world’s longest snake species, with some growing over 20 feet long. Their complex care and massive size puts them among the rarest pet snakes. Reticulated pythons are native to Southeast Asia. They require very large, customized enclosures with stable high temperatures and humidity.
Feeding such giant snakes is challenging and risky. Strict permits and licenses are also required to legally keep reticulated pythons in many areas. Due to their advanced care needs and legal restrictions, reticulated pythons are uncommon pets found only among the most dedicated specialty collectors.
Chinese Crocodile Lizards
Chinese crocodile lizards are a semiaquatic lizard species native to a small area of China and Vietnam. They get their name from their ridged, crocodilian-like scales. Chinese crocodile lizards are threatened by habitat loss and overcollection for the pet trade. They are also very difficult to breed and keep successfully in captivity.
These lizards have a highly specialized diet of hard-shelled crustaceans, fish, and mollusks. They require large freshwater aquariums with the proper temperature gradients and hiding spots. Very few private keepers and breeders work with Chinese crocodile lizards, making them extremely rare as pets.
Gila Monsters
Gila monsters are a type of venomous beaded lizard native to the southwestern United States and Mexico. They are sluggish lizards that feed on small mammals, birds, and eggs. Though fascinating, gila monsters are not common pets due to their highly toxic venom and specialized care needs.
Gila monsters require simulated desert enclosures with a hot basking area and cooler retreat. Their captive diets must be supplemented with minerals and vitamins. It takes significant experience and dedication to properly care for these venomous reptiles. Gila monsters are also regulated and require special permits in most areas, further limiting their availability as pets.
Exotic Invertebrates
Many unusual exotic invertebrates like large arachnids, insects, and crustaceans are rarely kept as pets due to their specialized care and legal restrictions.
Giant Centipedes
Giant centipedes from tropical areas across the world can reach alarming sizes over 12 inches long. Their venomous bite packs a painful punch. Keeping these exotic jungle centipedes requires meticulous attention to housing, temperature, humidity, and feeding needs.
Giant centipedes prefer to eat live prey and require enclosures with deep substrate to tunnel through. Their sensitivity to environmental changes and aggressive nature makes them pets only the most dedicated enthusiasts will take on. Laws also restrict keeping certain large, dangerous centipede species in many areas.
Giant Wetas
Giant wetas are bulky, cricket-like insects native to New Zealand. Different species can reach sizes over 4 inches long. Wetas are predatory invertebrates that prefer to eat other insects like roaches. They require roomy, well-planted terrariums and higher temperatures between 70-80 °F.
Giant wetas are not commonly bred or kept as pets. Their large size and unique care needs, as well as legal restrictions on exporting some species, contributes to their rarity in captivity. Exotic pet owners interested in a unique insect experience may be able to source captive-bred specimens.
Japanese Spider Crabs
Japanese spider crabs are the largest crab species in the world, reaching up to 12 feet claw to claw. Their huge size and specialized aquatic habitat makes them extremely challenging captives. Most spider crabs in home aquariums are smaller juveniles.
Adult Japanese spider crabs require a huge, professionally-designed aquarium with pristine water conditions. They are delicate animals despite their intimidating appearance. Most aquarists do not have the resources to properly house these giant crustaceans. Their massive size and advanced husbandry techniques put Japanese spider crabs among the rarest pets to keep.
Wild-Caught Species
Certain animals that are still commonly taken from the wild rather than captive-bred are increasingly rare as pets due to legal restrictions designed to protect wild populations.
Monkeys
Though some monkeys like marmosets and tamarins have established captive-bred populations, many monkeys available in the pet trade are still sourced from the wild. Removing monkeys from their natural social groups and environments often leads to severe stress, loneliness, and inadequate care from inexperienced owners. Increased government regulation aims to curb the harmful trade in wild primates.
Owning wild-caught monkeys and other primates as pets is now illegal in most developed countries. Permits are required in the U.S. to own any primate species. Though still available from less scrupulous exotic animal dealers, the practice of keeping wild-caught monkeys as pets is increasingly rare and taboo.
Chimpanzees
Chimpanzees face an endangered future in the wild. Their high intelligence and complex social needs make them unsuitable pets. However, chimps were historically taken from Africa as babies to be pets, performers, or biomedical research subjects. Increased protections now make owning a chimp extremely rare.
Chimp ownership is broadly illegal and requires special exemptions. Even accredited zoos today seldom keep chimps due to their intense care requirements. Conservation education has helped change attitudes toward viewing chimps as exotic pets or property for human exploitation. Removing chimpanzees from wild populations for captivity remains a threat to the species but is increasingly uncommon.
Cheetahs
Cheetahs are one of Africa’s most vulnerable wild cat species. Cubs were regularly taken from the wild to be exotic pets or captive hunting animals. However, the high cost of providing proper housing and diet for cheetahs makes them impractical pets outside of zoos.
International trade in wild cheetahs is now illegal. Cheetah populations continue to decline due to habitat loss, and every remaining animal is important to the species’ survival. While captive-bred cheetahs are still kept in some zoos and parks, the practice of capturing wild cheetahs for pets has fortunately faded due to regulation and changed attitudes.
Conclusion
Determining the absolute rarest type of pet is challenging. Rarity stems from a combination of exotic origin, specific care needs, limited captive breeding, regulations that restrict ownership, and the difficultymeeting the complex physical and social needs of wild species in human homes. Some of the rarest pets today are exotic mammal species like sugar gliders, kinkajous, and capybaras. Uncommon birds such as hyacinth macaws, palm cockatoos, and superb lyrebirds are also rarely kept by the average pet owner.
Reptiles like reticulated pythons, Chinese crocodile lizards, and gila monsters represent some of the rarest exotic pets due to their size, venom, or husbandry requirements. Invertebrates such as giant centipedes, wetas, and Japanese spider crabs are similarly demanding to keep. Finally, decreased trade in wild-caught species like primates and big cats make them increasingly uncommon pets outside of zoos. With better education on animal welfare and conservation, letting rare species remain in the wild is the responsible choice for pet owners today.
