Understanding the Differences Between House Pets and Domestic Livestock
The term "pet" typically brings to mind lively dogs and affectionate cats. These furry companions are deeply embedded in many people's daily lives. According to the 2021-2022 National Pet Ownership Data, nearly 70% of households have at least one pet. But are dogs and cats the only types of pets? How are pets distinct from other domesticated animals? These questions are common for those interested in learning about pet classifications.
Domestic animals versus pets – What sets them apart? Domestic animals are bred specifically for living with humans in captivity, often for economic reasons such as providing meat, milk, wool, leather, or assisting with farm work.
Examples of domestic animals include cattle, camels, chickens, goats, horses, and donkeys.
Though these animals may be considered pets in a broad sense, they differ from typical household pets. Pets are animals or birds kept primarily for companionship, with strong emotional bonds to their owners, living within the household environment.
Which animals are recognized as pets? Almost any creature can become a pet, but most people commonly keep specific animals, birds, and fish. Popular pets include dogs, cats, fish, parrots, turtles, snakes, frogs, cockatoos, parakeets, hamsters, rabbits, mice, rats, guinea pigs, and ferrets.
Most favored pets in households People across the nation are passionate about animals, with some types being more popular. Here are the leading pets found in homes:
Dogs Dogs hold the top spot globally, with about 69 million households owning one, according to the latest Pet Ownership Survey by the American Pet Products Association. Their loyalty, protective nature, easy training, affordability, and friendly demeanor contribute to their popularity. The Labrador Retriever is the most common breed, followed by French Bulldogs, Golden Retrievers, German Shepherds, Poodles, Bulldogs, Beagles, and Rottweilers.
Cats Introduced to North America centuries ago to control rodents, cats are now the second most common pet. Despite being less loyal than dogs, cats are loved for their curiosity, playfulness, independence, and affection. Popular cat breeds include Ragdoll, Exotic Shorthair, Persian, Maine Coon, Siamese, American Shorthair, Scottish Fold, and Devon Rex.
Fish About 12% of households keep fish, making them the third most popular pet. Many enjoy fish for their aesthetic appeal and ease of care. Freshwater varieties like Goldfish, Cory Catfish, Mollies, and Swordtails are preferred over saltwater species, primarily due to lower maintenance costs.
Birds Nearly 10 million homes keep birds, which are known for their color and melodic sounds. Birds capable of mimicking human speech, such as parrots and cockatiels, are especially popular. Other favored birds include Budgerigars, Doves, Green-cheeked Conures, Cockatoos, Hyacinth Macaws, Parakeets, and Finches.
Reptiles Though some may find reptiles intimidating, many enthusiasts keep them as pets. Over 5.5 million households have reptiles like Leopard Geckos, Corn Snakes, Bearded Dragons, African Sulcata Tortoises, Ball Pythons, Red-eared Sliders, Chameleons, and Blue-tongued Skinks. Reptiles are favored for being quiet, low-maintenance, and long-lived pets.
Hamsters With over 1.5 million households, hamsters remain a favorite small pet. Known for their cuteness and ease of handling, they don’t require extensive training or space, making them ideal for many families. They are also affordable and minimally demanding of attention.
