The Clever Cavy


Guinea pigs are rodents from South America, originally domesticated by the Incas of Peru roughly 7,000 years ago.  Their relatives are Cavy Porcellus, found in Brazil and Cavy Boliviensis, located in the high Andes, and Cavy Cutleri which lives in Peru.  Scientists now believe these cavy companion were possibly domesticated from an extinct wild species that lived in northern and western South America.   Domestication efforts have come a long way since the Incas.  You can find guinea pigs everywhere from the family couch to training camps!

So I think we can agree that guinea pigs are pretty darn cute and have fascinating abilities, but there are some important needs that must be addressed. Cavy Care is not something to take lightly. Guinea pigs are more complex and require more care than most people realize. Here are a few things that you need to consider:


  • Guinea pigs should be spayed or neutered, and they reach sexual maturity very fast.  A male reaches sexual maturity at 3-5 weeks and females in 4 weeks!
  • Guinea pigs are very social animals. They require daily quality time and interaction with their human family.
  • Because of they are highly social, they do better when housed with another guinea pig buddy.  They should be kept in pairs or, preferably groups, unless there is a specific medical condition that requires isolation. Lone guinea pigs are more likely to suffer from stress and depression.
  • They have 20 teeth that continue to grow throughout their lifetime
  • Their nails require regular trimming
  • They have 340˚ field of vision, but have poor depth perception, and see only a few colors
  • They eat 6% of their body weight daily!
  • Guinea pigs have what are known as “open rooted” teeth, which means the teeth grow constantly throughout their lives. They need unlimited access to foods, especially grass hays, to help grind down their teeth in order to keep them at the proper length and alignment.
  • Guinea pigs are unable to manufacture Vitamin C within their bodies; therefore, this vitamin must be supplemented.  My previous post discusses how  you can do it.
  • They share an unusual behavior with rabbits: coprophagy – eating their poop.  However, this is normal behavior and is needed to remain healthy.  Learn more here.
  • They need regular exercise outside of their enclosure! Learn more here.
