Vitamin C

  • Guinea pigs require vitamin C in their daily diet for optimal health
  • Guinea pig pellets are fortified with vitamin C, but the expiration date on the bag is important!
  • Fresh fruits and veggies that are high in vitamin C are vital
  • We recommend a daily vitamin C tablet for all guinea pigs (Oxbow makes a great supplement)
  • We DO NOT recommend vitamin C drops for the water- they break down quickly and taste bad


  • Use a hanging water bottle or multiple open bowls
  • Change water daily and check that water sippers don't become clogged



  • Cardboard boxes, wicker baskets and durable parrot toys make great toys
  • Make sure your guinea pig has comfy places to hide




  • Guinea pigs make a huge variety of sounds (chutt, tweet, purr, etc)
  • Guinea pigs are social, but prefer minimal handling


  • We recommend neutering if kept in mixed gender groups or having aggression issues
  • Female guinea pigs should not be bred if over 1 year of age
  • Guinea pigs are prey species and they will hide their illnesses, so bring them in promptly
  • A guinea pig that does not eat or pass droppings for >12 hours needs emergency care!
  • Other common signs of illness include: heavy breathing, sneezing, eye/nose discharge, small/hard droppings, tight abdomen, tooth grinding, drooling, bald patches, flaky skin, dribbling urine, bald sores on feet, unusual aggression



  • Guinea pigs require a room or a pen that is at least 2 x 3 ft wide
  • They are not great jumpers so 10 inch high walls should be sufficient to keep them in
  • Solid flooring (no grates) is necessary for all living spaces
  • The floor should be lined with paper pulp bedding (carefresh), newspaper or similar
  • Avoid cat litter and wood chips/wood shavings
  • Cover all cords in the guinea pig's environment with thick plastic tubing
  • Generally, do not allow dogs and cats or rabbits to have contact with guinea pigs


  • Regular nail trims are needed for all guinea pigs
  • Long-haired breeds (Pervian/Silkie) require careful attention and brushing to prevent matting
  • Some male guinea pigs require regular cleaning of their rectal/scrotal region
