This means that although iceberg lettuce is not toxic for your guinea pigs, feeding too much iceberg lettuce can cause digestive issues and diarrhea which aren’t good.

Can They Eat Romaine Lettuce?

The main part of daily diet for your guinea pig should be made up of a mixture of leafy greens and vegetables. Feed 1-3 cups of these mixed leafy goodies to your guinea pig daily. Be careful when feeding your guinea pigs Romaine lettuce however because even though they will benefit somewhat from the Vitamin C that Romaine lettuce contains, it is also very high in calcium.

Guinea pigs need calcium in their diet but eating foods that are high in calcium too often can cause them to have white pee. If you observe this symptom in your guinea pigs, stop feeding any veggies high in calcium until you consult your veterinarian.

A prolonged diet that is too high in calcium, for example, feeding Romaine lettuce daily, could cause calcium build up and lead to inoperable stones which is potentially deadly for your guinea pigs. Feed Romaine lettuce only in moderation or at the direction of your veterinarian.

Is Lettuce Bad for Guinea Pigs?

So, when it comes to lettuce, it’s not automatically “bad” for your guinea pigs. Like anything else, you need to exercise your best judgment and observe your pet for any changes in behavior, urine, or feces. Lettuce is high in water content and thus it can cause your guinea pig to have soft droppings. If you are alert to changes in your pet, such as soft droppings, lethargy, or diarrhea, you will be able to adjust their diet accordingly. Feed Iceberg and Romaine lettuce in moderation and include plenty of other leafy greens, fruits, and veggies.
