Can You Feed Them Watermelon Rind And Seeds

Yes, the watermelon rind and seeds are acceptable because the seeds are soft, the rind does not have a lot of water, and it is also very fibrous. The texture of the watermelon rind is such that it gives guinea pigs a good bite. These rodents have teeth that keep growing, and they need to eat foods that make their teeth remain trimmed due to the hard texture.

Watermelon rind has a hard texture which gives guinea pigs a chance to keep their teeth trimmed due to the constant erosion and grinding. Watermelon rind also has all the nutrients without the high water content so it can be a better food to serve to guinea pigs than the fruit itself.

The seeds of watermelons are softer than many other fruit seeds and therefore they pass through the digestive tract easily. It will not be a choking hazard, and neither will these seeds cause any impaction in guinea pigs. Check out Can Guinea Pigs Eat Raspberries.
