By January 1, 1970April 1st, 2022No Comments


Feeding: –


Guinea pigs eat little and often.


  1. Hay is most important and must be fresh and available at all times.
  2. Fresh water available at all times, remember to clean out water containers daily.
  3. Vitamin C must be provided daily, in the form of fresh (not frozen) greens, vegetables, and fruit or freshly picked (not mown) grass. Buy or borrow a book from the library and find out which plants are safe for your guinea pig to eat.
  4. Feed small quantities of guinea pig mix twice daily (e.g. GUINEA PIG NUGGET) throw away stale food. Introduce new foods gradually and feed greens, veg, fruit, in moderation.  Never feed wet or wilted greens.
