Health Benefits of Guinea Pigs Eating Leaves

  • Good immunity – with the good minerals and vitamins, and the antioxidants, the guinea pig will have much better immunity. There will be less diseases, the appetite will be normal, the fur and coat will look healthy, and there will be less risk of any infections.


  • Electrolyte balance – the potassium mineral contributes to a good balance of salts (electrolytes) and water in the body. When the body has an imbalance in electrolytes vs. water, it shows as fatigue or low blood pressure and dizziness.


  • Prevention of scurvy – with vitamin C, guinea pigs are safe from scurvy. This disease can even be fatal for them and at first, it manifests with a rough coat, internal bleeding, loss of appetite, and swellings in joints.


  • Energy – the proteins and certain vitamins/minerals give an energy boost that comes from proper nutrition.


  • Healthy blood – the iron found in leaves contributes to healthy blood and less risk of anemia.


  • Good oral health – munching on leaves or branches prevents teeth overgrowth in guinea pigs. They suffer from this naturally, that’s why they must chew on pellets or leaves and branches to stop the painful teeth overgrowth.

Nutrition Facts of Leaves

  • Antioxidants – benefits of antioxidants are countless. They protect the body from free radical damage. The free radicals cause many health problems and also cause premature aging in guinea pigs. Also, with antioxidants the heart is healthier, the risk of infections is lowered, and there is even less risk of some cancers.


  • Potassium – this mineral is regulating the electrolyte and water balance, also removes fatigue, weakness, muscle aches. Also, it makes the bones stronger and relieves constipation.


  • Vitamin A – this vitamin acts as an antioxidant. Basically, it goes in the body and ‘hunts down’ the free radicals. It fights inflammation, keeps the brain functioning well, improves the quality of skin and vision. Also, it keeps kidneys, lungs, and heart healthy too.


  • Vitamin C – The vitamin C creates collagen tissue and it helps in faster healing of the wounds. This vitamin is crucial for the guinea pigs because without it they are prone to scurvy which is fatal for them. The guinea pigs can’t produce this vitamin naturally, and they can’t store it as reserves, so they must ingest it through food or supplements.


  • Protein – the protein is the best source of energy, next to the carbs. Proteins have a slow release of energy and warmth that lasts throughout the day.


  • Iron – this compound is crucial for healthy blood, and without it, the body is prone to anemia.

Risks to Consider When Feeding Leaves to Guinea Pigs

  • Urinary problems – the tree leaves might contain traces of calcium. The mineral calcium is harmful to guinea pigs. They only need it when they are growing and in development, but fully grown guinea pigs cannot consume this mineral in normal or high amounts. Otherwise, calcium will pile up in their urinary tract and cause urinary problems. The problems manifest as: urinary infections, painful urinating or blood in the urine. Also, bladder or kidney stones will likely appear in guinea pigs, and if this is not treated on time, it can be fatal and result in renal failure.


  • Upset stomach – anything that is consumed too much is not good, regardless if it is a healthy food or not. So, too much leaves or branches might upset the fragile stomachs of the guinea pigs.
