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

Well, you can…. in moderation.

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

Moderation = Approximately a 1-3 tablespoon-sized amount of courgette is enough squash for one guinea pig.

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

They will likely not eat it at this point, and 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 percent, should be made up of guinea pig food and hay.

You should feed this amount no more than one to two times per week and no two days in a row.

Is Courgette Harmful to Guinea Pigs?

Yes, courgette can be.

Too much courgette fed to these little buddies can give them side effects like an upset stomach, gas, bloating, and diarrhea.

This can lead to a multitude of problems including things like dehydration and electrolyte imbalances that could impart a trip to the veterinary clinic for your pocket pet vet to fix.

These three factors to keep in mind include:

Harmful Reason #1: Loose Stool/Diarrhea

Too much of any fruit or vegetable can produce hypermotile, or increased movement, of one’s digestive tract.

Some guinea pigs are more sensitive to additional foods or changes in their diets, so they are more likely to have loose stool and in some cases, full-blown diarrhea.

Other guinea pigs will not be impacted by any additional changes in their diets.

Harmful Reason #2: Allergic Reaction to Courgette

A guinea pig can develop an intolerance or an allergy to any food, so there is always the possibility that your pet is allergic to courgette.

If you suspect your guinea pig is allergic to courgette do NOT feed this food to your pet.

If your guinea pig is allergic to cucumbers and accidentally ingests it, go to your nearest animal emergency room immediately.
