Lettuce may not be the optimal diet choice for guinea pigs as its nutritional value is low and contains too much water; they need adequate supplies of essential vitamins and minerals in their food for good health.
Other lettuce varieties such as Romaine or butterhead make a better selection for creating salads for guinea pigs. You can combine it with other vegetables and fruits in order to provide them with optimal healthful eating environments.

High Water Content
Iceberg lettuce may not be toxic, but its high water content can lead to diarrhea in some guinea pigs. By including other foods that are safe for them and providing hay into their diets, additional measures will help balance out this water content and prevent issues from arising.
Other varieties of lettuce such as green leaf and Romaine varieties can also be safely fed to guinea pigs regularly, as these contain less water and provide greater nutritional value. It is advised to add vegetables and fruits into their daily diet to provide essential vitamins that cannot be obtained solely through lettuce consumption alone, while breaking up their monotonous routine of only eating one type of food at once.
Guinea pigs should consume 80-90% of their diet as high-quality grass hay for optimal health. Hay provides vital fiber, helps wear down teeth, and provides digestive support. Other foods, including fresh fruits and vegetables as well as dark leafy greens may be consumed occasionally as part of a balanced diet; however, they should never replace the mainstay: grass hay!
Low Nutritional Value
Iceberg lettuce contains limited nutrients and fiber needed by guinea pigs for optimal health, and eating too much could cause stomach upset or diarrhea, and may affect their balance of bacteria in their gut.
Dark leafy greens like Romaine, Cos, or Little Gem lettuce provide more nutrients. Kale, parsley and collard greens should also be offered alongside it to ensure your pet receives all the essential vitamins and minerals.
As an additional layer of protection against vitamin C deficiency and potential scurvy, make sure that they receive plenty of fruit-rich diet including vegetables and hay as treats from time to time. A small treat might do just fine!
Deficiency of Vitamin C
Your guinea pig needs a balanced diet that contains plenty of fruits and vegetables in order to obtain adequate amounts of Vitamin C. Due to a genetic mutation, they cannot produce their own vitamin C supply, meaning fresh produce such as fresh veggies or fortified pellets must provide this essential source.
Avoid feeding your pet iceberg lettuce as this offers little nutritional benefit and is mostly made up of water. Instead, opt for romaine or bibb lettuce which contain more essential vitamins and nutrients; other excellent choices are green or red leafy vegetables such as turnips, endive, or carrot tops; fruits should only be offered occasionally as their high sugar content adds nothing of nutritional value to your guinea pig’s diet.
Your guinea pigs will obtain enough vitamin C through a diet consisting of timothy hay, pellets fortified with Vitamin D and fresh vegetables. When selecting quality pellet brands that only use timothy as the main ingredient and do not contain seeds or dried fruit as additional components.
Bladder Stones
Bladder stones are one of the more serious issues guinea pigs may develop, and are typically fatal if left unchecked. Bladder stones form when too much calcium is consumed over time; to minimize risk, provide a diet low in calcium; avoid foods like iceberg lettuce that contain too much.
Other varieties of lettuce such as romaine, butterhead, red and green leaf, Swiss chard and cabbage offer your guinea pig more nutritional value than iceberg lettuce and tend to contain higher concentrations of Vitamin C, essential for their health.
Keep an eye out for any signs that your guinea pig might be sick, such as straining to urinate or pass their feces. If they appear uncomfortable or lethargic, see your vet immediately to get assessed for bladder stones and treated if necessary.
