Since feeding your guinea pig a healthy diet is so important , you may be wondering if avocados are a part of that diet. There’s a lot of misinformation out there about whether or not they can eat avocados, so let’s clarify a few things:

No, guinea pigs shouldn’t eat avocados because there are healthier options available. Avocado flesh has lots of fat and calories, which causes health issues like obesity and diarrhea. Plus, there’s a toxic chemical called “persin” in the seeds, bark, leaves, and pits of avocados that can kill guinea pigs.

Why Guinea Pigs Shouldn’t Eat Avocado

a tip that remind people that although technically guinea pigs can eat avocado flesh, it's not the healthier option for guinea pigs
Technically, guinea pigs can eat avocado flesh, but it’s so high in calories and fat that you shouldn’t even bother with it.

There’s a laundry list of reasons why guinea pigs shouldn’t eat avocado. Unfortunately, the high-fat content is just the beginning. Avocados can also cause:

1. Digestion Issues

The rich , fatty content of avocados can cause digestion problems in guinea pigs. When piggies eat avocados (especially in large amounts), this fruit can lead to an upset stomach and even diarrhea. This is because guinea pigs’ digestive systems are not used to processing high levels of fats.

If your guinea pig has eaten avocado (or at least huge amounts), you may notice some changes in their poop. These can include diarrhea, mucous in the stool, and even blood.

If your cavies are having any of these symptoms, stop feeding the avocados right away. Then put them hay and pellet-only diet for 24 to 48 hours. That should help their digestive system to calm down and take care of the problem.

If things don’t improve in that period, take your guinea pig to a vet as soon as possible. Delaying can prove fatal for them.

2. Bladder and Kidney Stones

Avocadoes have the mineral calcium in it. That means that when guinea pigs eat avocado (once again huge amounts of avocado), it can increase the risk of them getting bladder and kidney stones.

These health problems can be very serious and even fatal if not treated in time. The stones develop in cavies because the calcium can’t be absorbed properly by the guinea pig’s body. The excess amount of calcium can deposit into their urinary tract and develop stones.

If you notice your cavy can’t urinate, is struggling to drink water, or keeps making painful noises while peeing; take them to a vet immediately. That can indicate that they might be struggling with bladder and kidney stones.

3. Toxic To Guinea Pigs

Some parts of an avocado is toxic to guinea pigs. The leaves, pit and skin of the avocado can cause health problems in these animals, leading to serious illness or even death in some cases.

The toxin “persin” is found in all parts of the avocado plant , but some of the highest levels are found in the leaves .

Piggies like to nibble on everything they can get their hands on. If you have an avocado tree in your backyard, make sure to keep it away from them for their own safety.

“Persin” can cause a wide range of health problems for your little friends. These include respiratory distress and congestion , loss of appetite and weight loss , bloating and other digestive issues, heart enlargement , liver damage, death and more.

4. Weight and Cardiovascular Problems

Fat means flab, and an avocado-heavy diet can cause your guinea pig to balloon in weight. This is due to the high-calorie, high-fat content of avocados.

While all that extra padding might make your guinea pig look cute, it can lead to some serious health problems. Excess weight can put strain on your cavy’s heart and can even lead to cardiovascular problems.

If you want your piggie to stay healthy, it’s important to keep their weight in check. And that means not overfeeding them with avocados (or any other high-fat foods).

Nutritional Stats of Avocado

Let’s do a quick rundown of the nutrients in avocados. Not everything in it is bad. There’s actually a few good nutrients in them that could be healthy for piggies. It’s just that the bad outweighs the good.

The information below is based on 100grams of avocados:

  • Water: 73.2 g (hydration food sources are always a win)
  • Calories: 160 (WAYYYY too high)
  • Fat: 14.7g (come on, this is a no go)
  • Carbohydrates: 8.53g
  • Fiber: 6.7g (can help with digestion, but it’s battling with the high fat content; big “no-no”)
  • Calcium: 12mg (it’s actually on the lower end and wouldn’t cause much damage if fed in moderation; overfeeding is the key issue)
  • Sodium: 7mg (yay!)
  • Iron: .55mg (not a lot, but can still be helpful)
  • Vitamin C: 10mg (needed by piggies to prevent scurvy)
  • Folate: 81mg (perfect for a pregnant guinea pig)
  • Vitamin A: 7mg (also can help with night vision, but can be harmful if overfed)

What Happens If I Give My Guinea Pig Avocado?

a decision tree to help people understand if they should feed their guinea pigs can eat avocado
I recommend that you avoid avocado, but if you’re still debating if you can feed it to your guinea pigs, this decision tree should help you.

If you give your guinea pig avocado – especially if you give them a lot of it – they can suffer from some very serious health problems.

These can include:

  • Bladder and kidney stones
  • Weight and cardiovascular problems
  • Digestion issues
  • Respiratory distress and congestion

Based on what’s in avocados, it’s not a good idea to give them to your guinea pig. There are better sources of nutrients out there that will be more beneficial for their health.

If you’re still intent on giving them avocado (or if they’ve already snuck into your cavy’s diet), make sure you just feed them a very, very small amount of the avocado flesh. Don’t give them any skin, pit, leaves, or anything else from the avocado. These are all toxic to cavies.

Can Guinea Pigs Eat Avocado Skin?

No, guinea pigs can’t eat avocado skin. If they eat it, they can suffer from digestive problems and other health issues. Plus, it has the chemical persin in it , which can be very dangerous to these animals.

Can Guinea Pigs Eat Avocado Flesh?

Yes, technically guinea pigs can eat avocado flesh is very, very small amounts- and very infrequently. But, I wouldn’t recommend it. There are so many healthier options for guinea pigs to eat, it’s not worth exposing them to the high fat content in the fruit.

Can Guinea Pigs Eat Avocado Leaves?

No, guinea pigs can’t eat avocado leaves at all. It’s probably the most lethal part of the avocado plant. If they do, they can suffer from respiratory distress, congestion, loss of appetite, weight loss, and other health problems. Plus, the leaves have a high concentration of the toxin persin, which can be fatal to guinea pigs.

Can Guinea Pigs Eat Avocado Peel?

Avocado peel is an alternative name for avocado skin. So, it’s pretty much the same thing. So, can guinea pigs eat avocado peel? Unfortunately, no. Guinea pigs can’t eat avocado peel, because, like all other parts of an avocado plant, the skin contains high levels of persin , which can kill guinea pigs.

Can Guinea Pigs Eat Avocado Pit?

No, guinea pigs can’t eat avocado pits. Avocado pits can be dangerous to guinea pigs. If they try to eat it, they can choke on it. Plus, the pit contains a high concentration of the toxin persin, which can be fatal to guinea pigs.

Can Guinea Pigs Eat Avocado Seeds?

Guinea pigs can’t eat avocado seeds safely. Seeds is another name for avocado pit. The pit can’t be fed safely, because it has the chemical persin in it, which can be fatal to guinea pigs.

Can Guinea Pigs Have Avocado Oil?

Guinea pigs can’t eat avocado oil safely. It has all the same high-fat content as the fruit itself, which can cause health problems for guinea pigs if they eat it too frequently. So, avoid feeding your cavy avocado oil.

What About Avocado Baby Food?

Technically, avocado baby food can be fed to guinea pigs safely because the avocado flesh has been pureed and strained and watered down. It’s low in fat and calories and high in water content.

But, the high water content can lead to other health issues for cavies like diarrhea and other digestive problems. So, it can be fed to them, but I wouldn’t recommend giving it to your guinea pig. Like I said before, there’s tons of healthier options.

Can Pregnant Guinea Pigs Eat Avocado? 

Pregnant guinea pigs shouldn’t eat avocado. Since avocado is so high in fat and calories, it’s not a good idea to give it to pregnant pigs. Pregnant cavies need to watch their weight or else can can have a difficult time giving birth. They can get all the nutrients they need from other, healthier foods.

Can Baby Guinea Pigs Eat Avocado?

Although baby guinea pigs can eat solid foods almost from the moment they’re born, avocados shouldn’t be given to these young animals. The high fat content is very unhealthy for baby guinea pigs. Instead, stick to leafy greens, fresh fruits, and other safe baby guinea pig foods.

Should Guinea Pigs Eat Avocado?

Guinea pigs shouldn’t eat avocado. The risk of giving it to them isn’t worth the potential health problems they can suffer as a result of eating avocado. It can cause digestive issues and weight problems when they eat too much of it.

It’s better to keep guinea pigs on a low calorie, high fiber diet. Honestly, there’s so many more healthier options that it doesn’t make sense to feed them avocado.

That way, your fur babies can stay in shape and live long healthy lives.

Is Guacamole Good for Guinea Pigs? 

Guacamole is made from avocados, so it’s not good for guinea pigs. It’s high in fat and calories, which can lead to lots of health problems for cavies. When it comes to guinea pigs, it’s best to stick with safe, healthy foods like low calorie leafy greens and low sugar fruits. Of course, high quality hay, grass, and guinea pig pellets should be staples in your piggies diet, too.

What Can I Give My Guinea Pig Instead Of Avocado?

  • fresh fruits like apple, bananas, and grapes
  • fresh vegetables like broccoli, carrot, mustard greens, and spinach
  • hay pellets or Timothy hay
  • watermelon or other melons

As long as you feed your fur babies these foods in the appropriate serving sizes, they can live long healthy lives. A/nd reap the rewards of a healthy, balanced diet.

Foods Guinea Pigs Cannot Eat

Of course, there’s a lot more foods that guinea pigs can’t eat besides avocado. Here’s a list of the most common ones:

  • nuts (all varieties)
  • apple seeds (or pips) – actually most hard seeds should be avoided
  • beans and peas and lentils
  • bread products like bread, muffins, buns, or pastries 
  • pastas and rice
  • uncooked potatoes
  • anything moldy or spoiled – can contain toxins that can make guinea pigs very sick
