Here's why:
* High in sugar: Citrus fruits are very high in sugar, which can cause digestive problems in baby guinea pigs.
* Acidic: The citric acid in citrus fruits can irritate their sensitive digestive system.
* Not a natural food: Guinea pigs are herbivores and their natural diet consists of grasses, hay, and vegetables.
Instead of citrus fruits, offer your baby guinea pig:
* Fresh hay: This should be the staple of their diet.
* Fresh vegetables: Choose leafy greens like romaine lettuce, cilantro, and parsley.
* Timothy hay pellets: These are a good source of nutrients.
* Small amounts of fresh fruits: Opt for safe options like strawberries, blueberries, and bananas in moderation.
Always consult a veterinarian for specific dietary advice for your guinea pig. They can provide personalized guidance based on your guinea pig's age, health, and any other factors.
