Most things about cavies are adorable. Be it their size, the way they scamper on their wheels, and the way they stuff their mouths with food.
Speaking of food, cavy – especially guinea pig – parents have recently become interested in whether their pets can chow down on leaves.
Can guinea pigs tree leaves? Yes, guinea pigs can eat leaves and even branches, but you must be careful to feed your pet the right types. For example, guinea pigs do well with apple, banana, pear, and grape tree leaves, but you should keep not feed them iris, tulip, or bluebell leaves, among others.
I’ve compiled an absolute treasure trove of information about feeding these little cavies leaves. All you have to do is grab a comfy seat and read on to catch the 411 on guinea pigs and tree leaves!
Can Guinea Pigs Eat Leaves?
Guinea pigs are the original vegetarians. They’re herbivores – which means they don’t consume meat. In the wild, these little critters prefer to chow down on grass, hay, barks, twigs, leaves, etc.
Domesticated cavies have a more refined palate apparently, and generally eat timothy or alfalfa hay pellets, along with a few necessary minerals and vitamins.
So, if you want your cavy to get in touch with its wild side, you can feed it leaves. However, it’s best not to go wandering around in your garden picking the first tree you see for its leaves. And definitely avoid any tree you can’t identify.
You also want to be extra careful about plant leaves. A whole variety of plants are poisonous for your cuddle-bug, especially evergreen plants, and plants that grow from a bulb.
Here’s a list of plants that are poisonous to guinea pigs. Make sure to give these a wide berth if you’re planning on feeding your cavy plant leaflets:
- Chive
- Onion
- Leek
- Spring onion
- Garlic
- Lili of the valley
- Anemone
- Snowdrop
- Hyacinth
- Iris
- Bluebell
- Boxwood
- Ivy
- Laurel
- Bindweed
- Rhododendrons

| Maple Leaves | No |
| Apple Tree Leaves | Yes |
| Lemon Leaves | Best avoided |
| Bamboo Leaves | Yes |
| Mulberry Leaves | In moderation |
| Grape Leaves | Yes |
We’ll explain in more detail below so you can take the best care of your guinea’s needs!
Can Guinea Pigs Eat Maple Leaves?
If you have a maple tree anywhere in your vicinity, you may feel tempted to feed its leaves to your cavy. But avoid that temptation at all costs because maple leaves are toxic to guinea pigs.
It doesn’t matter if they’re fresh or dead; maple leaves contain gallic acid, which can be fatal for cavies if ingested.
Can Guinea Pigs Eat Apple Tree Leaves?
Apple tree leaves can make a healthy and nutritious snack for your cavy.
Humans may not like munching on the green stuff, but you can be sure that apple leaves contain essential nutrients that are great for your pet health-wise. Plus, you don’t have to worry about your pet putting on an extra pound because there’s no excess sugar to worry about.
Can guinea pigs eat apple branches?
Guinea pigs can definitely chew on apple branches because there are no harmful chemicals involved. But, before sure to clean and prep the branch before presenting it to your cavy.
Get rid of stuff like moss, bugs, etc., and cut the stem into small pieces while getting rid of sharp edges. It’s also a good idea to soak the apple branch in warm water for a few minutes and give it a thorough rinse to eliminate any pesticide traces.
Can Guinea Pigs Eat Lemon Leaves?
You can feed your cavy lemons in minimal quantities because they contain Vitamin C; feeding your pet too much of the citrus fruit can result in stomach upsets because of the acidic content.
This is why it’s best to just avoid lemon leaves for your guinea pig to avoid any potential health issues like diarrhea and bloating.
Can Guinea Pigs Eat Bamboo Leaves?
Bamboo leaves are perfectly safe to feed guinea pigs. In fact, bamboo stalks and leaves contain fiber and Vitamin C – which is super-healthy for your pet’s digestive system and can ward off problems like scurvy.
Bamboo leaves will make a good winter-time treat because the plant stays green throughout the cold weather.
Can Guinea Pigs Eat Mulberry Leaves?
Mulberries are a great source of Vitamin C and can be fed to cavies in moderation. Similarly, mulberry bark and leaves can also make a delicious and nutritional treat for your cavy.
Be sure to wash the leaves thoroughly to eliminate contaminants like bugs, insecticides, and pesticides.
Can Guinea Pigs Eat Grape Leaves?
Grape leaves aren’t just safe for cavies to consume; they’re actually super healthy for your guinea.
Grape leaves contain nutrients like selenium, magnesium, copper, zinc, potassium, etc., which are all beneficial for your cavy’s overall health. Feeding your pet grape leaves will also help build your guinea pig’s immune system and aid in its body’s metabolic processes.
Nutritional Profile of Leaves
The dietary benefits of feeding your cavy leaves will depend on the type of leaves you choose. Nonetheless, some nutritional benefits are present across the board, and here’s what they are:
1. Balanced Electrolytes
Somehow potassium never gets the respect it deserves, despite being an essential mineral. Potassium is an electrolyte, and it’s also pretty important for plant growth. The mineral can help your cavy’s body improve fluid balance, muscle contractions, and nerve signals.
A deficiency of potassium can lead to an imbalance of electrolytes and cause worrisome problems like fatigue, loss of balance, low blood pressure, etc.
2. Enhanced Immune System
Almost all trees and plants contain antioxidants, which are molecules that help eliminate free radicals. While the name ‘free radicals’ sounds like the next big band in the world of rock ‘n’ roll, in science, they are the bad guys linked to several illnesses – like diabetes, cancer, and heart disease.
Believe it or not, cavies are susceptible to diabetes. And, that’s precisely why feeding them leaves that are filled with antioxidants is a good idea.
Not to mention, antioxidants also go a long way in aiding immunity. That means your pet may develop a stellar immune system that’ll ward off infections and other nasty problems.
3. Improved Appetite, Mood, and Sleep Cycle
Tryptophan is an amino acid found in most plants, and it plays a crucial role in regulating the sleep/wake cycle, enhancing appetite, and functions as a mood stabilizer. This amino acid is also necessary for growing guinea pigs and can help prevent conditions like cataracts.
Risks Involved in Feeding Guinea Pigs Leaves
What could possibly go wrong with feeding your cany a bunch of harmless leaves? The answer’s quite a bit – if you don’t know what you’re doing.
Apart from that mile-long list of leaves that are poisonous to cavies, here are some of the downsides of feeding your pet leaves:
1. Bladder Stone and Urinary Issues
Putting guinea pigs and bladder stones in the same sentence sounds ridiculous. I mean, are cavy bladders even big enough to develop stones? You betcha! That’s why you want to avoid giving your cavy leaves too often because they might contain calcium.
Pregnant and growing guinea pigs need plenty of calcium, but adult guinea pigs don’t deal with the stuff too well.
Too much calcium in your little pet’s body can lead to oxalate, which invariably leads to bladder stones. If bladder stones aren’t caught in time, this can lead to renal failure or be fatal for your pet.
Additionally, high calcium traces can also lead to a build-up of the mineral in your cavy’s urinary tract (ouch). This can cause urinary infections and lead to painful urination.
2. Diarrhea and Bloating
Whenever you’re making your pet try out something new, there’s always a chance it won’t agree with your cavy.
Guinea pigs may share identical physiologies, but that doesn’t mean your pet’s individual system doesn’t have its personal quirks. That means whatever works for other cavies may not work for your own.
That’s why some cavy parents have reported incidents of diarrhea and/or bloating after feeding their pet leaves. Diarrhea in guinea pigs needs immediate attention because it leads to dehydration and can be fatal in some cases.
Bloating isn’t life-threatening but is undoubtedly unpleasant for your little cavy to bear. So, err on the side of caution, and start by feeding your cavy something new in small quantities only.
