Remarkable Facts About Guinea Pigs That Aren't Common Knowledge

Facts about Guinea Pigs
Guinea pigs have become quite popular as household pets today, and a large part of the credit for this goes to their docile nature. In this Buzzle article, we will have a look at some interesting facts about these species.
Guinea pigs (Cavia porcellus) are South American rodents belonging to the Caviidae family of kingdom Animalia. They are called cavies in the United States, where they are popular as pets. A male guinea pig is called a boar, a female is called a sow, while their young ones are called pups.

Guinea Pigs (Cavia porcellus)
  • Though they are called 'guinea pigs', neither do they come from Guinea, nor are they related to pigs. Some believe that they were named guinea pigs, as they were sold for a guinea―a gold coin worth 21 shillings―in England.
  • They grows to a length of about 8 - 10 in and weigh between 1.5 - 2.5 lb. They have an average life expectancy of 4 - 5 years, but can live up to 7 - 8 years. According to the Guinness Book of Records, the longest living guinea pig lived for 14 years and 10.5 months.
  • These rodents are born with their eyes open. They sport a fur coat at birth. Although, they are small enough to fit into your palm at birth, they grow very fast. They can start running within four hours of birth.
  • The most common breeds are the American, Abyssinian, and the Peruvian guinea pigs. These breeds are differentiated on the basis of their fur coats. The American breed has a short and smooth fur coat, while the Peruvian breed sports long hair.
  • Like humans, they can't produce vitamin C on their own, so they have to depend on external sources for it. Fresh fruits, vegetables like carrots and broccoli, fresh hay, and green leaves like spinach and lettuce, should be included in their diet. Though, they only need to be fed once a day, they can occasionally have small meals.
  • Boars attain sexual maturity at 3 to 5 weeks of age, while sows attain maturity at the age of 4 weeks. Sows can carry litter even before they become adults. Being social animals, they prefer to stay in pairs, but keeping a male-female pair will not be easy, as they will go on a reproduction spree.
  • Guinea pigs have also been used in medical research. One such instance came in 1890, when they were used to test an anti-toxin developed for diphtheria. Even today, they are used in research work pertaining to human ailments such as tuberculosis, scurvy, and juvenile diabetes.
  • They can be good pets for kids because they don't bite or scratch like other rodents. As their teeth continue to grow with age, they have to be provided with some twigs or chew toys to ensure that they don't become too large.
  • They don't require vaccination, but they can suffer from ailments such as respiratory infections and diarrhea. Mange is observed to be a common cause for hair fall and excessive scratching in Guinea pigs. They also suffer from lice and fungal infections.
  • Cavies are easy to domesticate because they have a good memory. Their sharp senses of smell, hearing, and touch, compensate for their poor eyesight. When they are attacked by a predator, they tend to run haphazardly; it's their defense mechanism to confuse the predator.
  • Guinea pigs were domesticated for meat by ancient tribes. Come today, they have become an integral part of the diet in many parts of South America. People of Peru alone consume around 65 million guinea pigs every year.
Pro Tip: When selecting one as a pet, choose an alert and active individual, as the ones which are very quiet and calm are likely to be ill. A healthy pet guinea pig can give you company for 7 - 8 years.
