Feeding Squash to Guinea Pigs | Possible Risks

Risks to Consider When Feeding Squash to Guinea Pigs

Here are the risks to consider when you feed guinea pigs with squash:

Urinary Problems

The calcium in the squash will severely damage the urinary tract in the guinea pigs. When they are young, they can ingest moderate amounts of calcium for strong bones.

But, when the guinea pigs grow up, they shouldn’t eat foods with lots of calcium. If they do, the calcium piles up in their urinary tract, and it can form kidney/bladder stones or even cause infections, blood in urine, and painful urinating.

Digestion Problems

Squash also has sugar. For a veggie, this amount is moderate, but still, this amount is not so good for the guinea pigs. They need small amounts of sugar. Otherwise, there is a risk of painful digestion, diarrhea, cramps, and gasses with higher amounts.

Serving Size and Frequency of Squash for Guinea Pigs

Preparation, Serving Size and Frequency of Squash for Guinea Pigs

As for the serving of a squash:

Step 1: Start by washing off the vegetable to remove any bacteria or harmful chemicals that could be present.

Step 3: One cup or a handful is enough.

Squash can be given to them 2 to 3 times a week.
