Guinea pigs can eat pumpkin, but only in small, infrequent amounts and with careful preparation. Here’s a concise guide:

• Safe parts: Fresh, plain pumpkin flesh (the orange part) is generally safe in modest amounts. Avoid seeds and skin if your piggie hasn’t tolerated skin well, and strip away the outer rind if you notice any issues. The flesh is the part typically recommended for treats.

• Feeding frequency and portion: Offer only small pieces—roughly two to three small chunks or a few bite-sized cubes once or twice a month. Pumpkin is high in natural sugars, so it should not replace hay and fortified pellets as the mainstay of the diet.

• Preparation tips: Wash the pumpkin, remove stems and seeds, and cut into tiny pieces. Feed raw; avoid cooked pumpkin or pumpkin pie fillings, which contain sugars, spices, or additives that can upset digestion. Remove any uneaten pumpkin promptly to prevent spoilage.

• Cautionary notes: The seeds can have a diuretic effect and are generally best avoided. If your guinea pig shows signs of digestive upset after a pumpkin treat, reduce or stop offering it and revert to a hay-pocused routine.

• General diet context: Hay should remain the staple, with fresh vegetables and a small amount of fruit or squash (like pumpkin) as occasional treats. Ensure a vitamin C–rich variety in greens and vegetables as part of everyday feeding.

If you’d like, I can tailor a simple feeding plan based on your guinea pig’s age, weight, and overall diet.
