A guinea pig is a type of pocket pet that resides in the cavie family of animals.

They are small animals that grow to a maximum of approximately 10-11 inches long, and can weigh up to 2.5 pounds as an adult.

In captivity and with proper care it is fairly common to see these pets live to 8 – 10 years of age.

One of their main anatomical (body) “quirks” is that they are constantly needing to chew in order to file down their teeth, as their teeth are constantly erupting (growing longer).

They are quite playful animals and love to socialize with the ones that they know and love.

They make great pets for responsible pet owners, and those living in small dwellings wanting a loveable pet that comes in a small package.

What Do Guinea Pigs Typically Eat?

Guinea Pigs eat an assortment of things to keep them healthy and happy.

  • High-quality guinea pig food and Timothy hay should be the main staples of their diet.
  • Up to about 10% of their diet can be made up of an assortment of vegetables and fruits, with fruits and vegetables over 12-24 hours old being discarded as soon as possible.
  • They require 30 – 50 mg of vitamin C daily from their diet, either in their guinea pig food, a vitamin supplement, or from fruits and vegetables that are high in vitamin C. I’ll get to this more here in a sec…
  • Guinea pigs do best with diets low in fats and sugars.
  • Clean, fresh, filtered, chlorine-free water. ‘Fresh water‘ means that is is changed daily. ‘Changed daily‘ means that new water is placed into a CLEAN water dispenser!

Let’s Talk Pineapples…

Pineapples are a type of tropical fruit with a unique shape and are rich in vitamins, enzymes and antioxidants.

They have a lot of health benefits for many, a sweet juicy fruit, and a popular shape that represents “welcome” to many.

Pineapple Nutrition:

Pineapple has quite a few health benefits, one of which is it’s high vitamin C content which can help promote a strong immune system, helping to fight infections and inflammation to support strong and healthy body functions.

Guinea pigs do not synthesize (make) their own vitamin C so they must get it from their diet to prevent called scurvy.

Many guinea pig foods have added vitamin C to supplement the guinea pig’s need for the vitamin.

Many cavy owners feed a variety of fruits and vegetables that contain vitamin C to ensure that their little friend is getting enough of this important vitamin in their diet.

Because pineapple is high in vitamin C, many guinea pig owners ask if they can serve their piggie the delicious juicy fruit to support the lack of vitamin C in their little buddies’ diet.

Pineapple has a high amount of sugar – increasing the chances of your pet gaining weight which only adds additional health worries to the guinea pig owner’s plate.

Pineapple is also rich in potassium and low in sodium and calcium, which can be important when we discuss the guinea pig and safety with pineapple below.

Can Guinea Pigs Eat Pineapple?

Well after learning about some of the health benefits and some of the risks that the consumption of pineapple brings with it, wouldn’t it be nice it you could just safely feed it to your piggy?

Well, you can…. in moderation. This means – in SMALL amounts.

That’s right, feeding a small amount of pineapple as a treat to your guinea pig on occasion is totally fine and they will likely LOVE you for it!

Moderation = A couple little cubes of pineapple is enough pineapple for one guinea pig.

In total, your guinea pig should have around 1/4 – 1/2 cup of fresh fruits and vegetables combined everyday, and no more than that.

If your pet does not eat all of their 1/4 – 1/2 cup of fruits and vegetables within 12-24 hours, then you need to dispose of it for them.

And that 1/4 – 1/2 cup should not consists solely of pineapple!

If your piggy does not eat the pineapple, it will only sit in their cage and get old and eventually become unsafe to eat.

The rest of their diet, the other 90% or so, should be made up of guinea pig food and hay.

You should feed this amount no more than 1-2 times per week and no two days in a row.

How About Pineapple Skin or Leaves?

The leaves and tough skin of the pineapple can be harsh and difficult to break down for your guinea pig and should not be offered to them.

These also can be a choking hazard so do not try it!
