Some Essential Guinea Pig Facts

Living Space

Here are a few basics about owning a guinea pig. First, a few golden rules:
  • Guinea pigs are very sociable, so keep at least two of the same sex together. I have no idea whether rabbits and guinea pigs make good companions.
  • Guinea pigs can be left on their own for a couple of days with a fair chunk of hay, but no longer; they need cleaning out quite regularly too.
  • Guinea pigs can be let loose in an enclosed garden as they can be lured back in with food, but be warned that cats will consider them fair game.
  • Handle with care! They cannot cope with drops of more than 5-10".
  • They need a simple single-level hutch to sleep in, and this can be kept outside all year round.
  • The hutch must be raised off the ground by at least a few inches, to reduce draughts.
  • The hutch must stay dry inside, so make sure it has a proper roof.
  • Make sure that all catches and hinges are secure. Guinea pigs aren't intent on escape, but they will do a runner if the opportunity arises.
  • A good supply of fresh water is essential, either by bottle or bowl.


  • Wood shavings make the best material for sleeping and toiletry.
  • Sawdust is too dusty
  • Straw can poke their eyes


  • Guinea pigs like to hide; use a 3-sided shoebox or lengths of carpet tube in the hutch.
  • When they're outside, make sure they have shelter.


  • Males shouldn't fight if they meet at a young age, and there are no female odours to aggravate them.
  • Purring is normal, and shows that they are happy with each other.
  • High-pitched squeaking usually means that they are hungry. Expect to hear this a lot!


  • Hay is essential. They should have hay at all times (or fresh grass, if unsprayed).
  • Try not to over-feed on non-hay foods.
  • They also need a fair supply of guinea pig mix (not rabbit mix). This is for Vitamin C.
  • Vitamin C is essential. It is found in any guinea pig mix, as well as fresh veg, goodlus tomatoes and bananas.
  • Guinea pigs much prefer to nibble slivers of vegetable, rather than gnawing at large chunks.
  • They are entirely vegetarian.
  • Do not feed them rhubarb.
  • Save spinach, carrot tops and lettuce as occasional treats.
  • Carrots in excess may also promote kidney stones, but no if they get plenty of exercise.
