Risks to Consider When Feeding Little Gem Lettuce to Guinea Pigs

Urinary Stones and Infections

Little gem lettuce has 30 mg of calcium. This mineral is very important for bone formation, but guinea pigs cannot consume it in large amounts.

Excess calcium in the guinea pig’s body will pile up as a mineral deposit in the urinary tract. So, the guinea pig could risk getting kidney or bladder stones.

You need to consult the veterinarian about resolving this problem because it can be fatal if this is not cured. The symptoms will appear in the urinary tract, including painful urination, frequent urinary infections, blood in the urine, and if uncured, the final stage is renal failure.
