Can Guinea Pigs Eat Pineapple?

Can guinea pigs eat pineapple? Yes, but it’s important that you feed this sweet, acidic treat carefully.

Pineapple isn’t the most traditional guinea pig treat, but it packs a good punch of Vitamin C, as well as relatively small amounts of Vitamin B6, potassium, and magnesium. There’s a bit of fiber there, too, so it can help to keep your cavy’s digestion working as it should.

But like all sweet fruits, pineapple contains a fairly large dose of sugar. Not only can that encourage obesity in cavies, but it can lead to diabetes as well. That’s something smart guinea pig parents know to avoid.

It’s also mouth-bitingly acidic, and it can cause the same sores for guinea pigs that it does for people!

The bottom line: pineapple is a great treat, but it should be fed infrequently and in small portions.

For those that are interested, we’ll take a closer look at why and how guinea pigs can eat pineapple and consider the pros and cons.

Is Pineapple Good For Guinea Pigs?

Yes and no.

I think he says yes!

All guinea pigs require an unlimited supply of Timothy hay and fortified pellets as the cornerstone of their diets. This provides the essential nutrition, fiber, and tooth-wear that every cavy needs.

But vets also recommend that every piggy get an additional cup of fresh veggies each day, filling any nutritional gaps–especially Vitamin C.

Pineapple is a great source of this essential nutrient, and as an occasional treat, it can help boost dietary intake to prevent dangerous scurvy.

That said, like most fruits, pineapple is relatively high in sugar. Vets recommend that all sugary foods be given in carefully limited amounts, as “high sugar foods in general, and particularly fruit, can destabilize the delicate balance of bacterial populations in the gut; they should therefore only be offered as treats.”

And beyond an adverse effect on gut flora, a high sugar diet can quickly lead to obesity. As experts warn, “just like humans, obesity in guinea pigs can lead to many other health problems such as fatigue, heart problems, back pain and diabetes if left unchecked.”

The take-away? Pineapple is a great source of Vitamin C, but its high sugar content can be a problem.

Is Pineapple Bad For Guinea Pigs?

Yes and no.

Pineapple is a great source of Vitamin C, and as guinea pigs need to eat plenty of sources of this essential nutrient, pineapple can be a great addition to their hay, pellets, and veggies.

But–and this is a big but–pineapple is also high in sugar.

It’s essential that sugary treats like fruit be limited. From gut problems to diabetes, too much sugar is really bad for cavies.

As the Humane Society says, “Fruit works well as an occasional treat that is offered once a day or several times a week. Keep the portion size small since fruit is high in sugar; a small wedge of orange or apple, several blueberries or a thin slice of banana is perfectly adequate. Kiwis, strawberries and citrus have high levels of vitamin C.”

Another problem with pineapple is that its famously acidic flavor can cause mouth ulcers in guinea pigs just as they can in people. Have you ever over-eaten an acidic food like tomatoes or pineapple, only to find an ulcer or two on your tongue?

The same thing can happen to guinea pigs!

As with all fruit, it’s important to avoid overfeeding.

Can Guinea Pigs Eat Pineapple Leaves or Skin?

No!

Pineapple leaves and skin are tough, abrasive, and sharp!

The skin and leaves of the pineapple are too abrasive for your cavy’s mouth.

Never offer your guinea pig pineapple leaves or skin!

How Should You Prepare Pineapple For Your Guinea Pigs?

As we mentioned above, you should never offer your guinea pig the leaves or skin. And sweetened, canned, or dried pineapple is a terrible idea.

Just say no!

After peeling a fresh pineapple, cut small pieces of the tender flesh for your cavy, perhaps even the fibrous core.

Pineapple doesn’t usually pose a choking hazard, so there’s no reason for a fine dice.

How Much Pineapple Should a Guinea Pig Eat?

Pineapple is a great source of Vitamin C, but its high sugar content means that it should be reserved as a treat.

We recommend 1 to 2 small pieces of pineapple, approximately the size of grape or cherry, no more than twp times a week. 

1 or 2 of these pineapple chunks, no more than two times a week!

Final Thoughts

Pineapple is an excellent source of Vitamin C, but its high sugar content means that it should be reserved as a treat. If you decide to offer pineapple, please keep the following things in mind:

  • Pineapple is a great source of Vitamin C.
  • But it’s high in sugar, so overfeeding can encourage obesity and diabetes.
  • Never offer pineapple leaves or skin to your guinea pig, and never give your cavy canned, sweetened, or dried fruit.
  • We recommend offering 1 to 2 small chunks, roughly the size of a grape or cherry, no more than two times a week.

If you stick to these guidelines, pineapple can make a great treat for your guinea pig!
