Yes, guinea pigs can eat cucumber and baby cucumbers, including the skin and seeds. It’s a refreshing, hydrating vegetable that most guinea pigs enjoy. However, cucumber isn’t as nutrient-rich as many other vegetables, so it should be fed in moderation alongside more nutritious greens.
Benefits of Cucumber for Guinea Pigs
- Hydrating and refreshing — High water content helps keep guinea pigs cool and hydrated, especially in hot weather.
- Safe skin and seeds — The peel and seeds are safe to eat and provide extra fibre, which supports digestion.
- Low in sugar — A good option for balancing sweeter fruits or veggies in their diet.
How to Safely Feed Cucumber to Guinea Pigs
- Frequency: A few times a week (not daily)
- Quantity: About a half-inch slice per guinea pig each time
- Preparation: Wash thoroughly (especially if not organic) and offer with the skin on
- Avoid: Feeding large amounts — cucumber is high in water and too much can cause soft droppings
💡🥒 Tip: On hot days, cucumber makes a great hydrating snack for your guinea pigs.
