Are you a new guinea pig owner?  Are you wondering if you can give them orange as a treat? 

 Guinea pigs make cute pets for those that do not have room for a dog or cat but they do have a special diet you need to follow.  Fruits are great for your guinea pig as long as they provide them with minerals and vitamins.  Read on to find out if they can have oranges as a special treat.  

Can a Guinea Pig Eat Oranges?

An orange does provide your guinea pig with the essential minerals and vitamins that they need, so this means that they can eat oranges, but only as an occasional treat.  They can also eat other fruit that is in the orange family, such as Clementine oranges, Mandarin oranges, and Lychees.  If your guinea pig has never had an orange before, start introducing it slowly so you can monitor their body’s reaction to this new addition to their diet.

If they seem to be accepting it with no issues, then you can start including it as treat in their diet.  If you make abrupt changes, such as just putting an orange in their cage, it can overwhelm your pet and they can suffer from upset stomach, diarrhea, and indigestion.

Can a Guinea Pig Eat The Skin and Pips?

Yes, your guinea pig can eat the skin of an orange.  The pips, or seeds, do need to be removed as these would be a choking hazard.  You need to make sure that there are no seeds left in the piece or slice you are feeding your guinea pig.  The orange peel has a lot of flavonoids and antioxidants that are beneficial for your guinea pig.  The sugar content is lower in the peels but you still have to be careful about the acidic level.
