Basic Guinea Pig Diet

In case you aren’t familiar with the basics of what a guinea pig should be eating, we’ll run through it quickly before getting into the specifics on lettuce.

80-90% of a guinea pig’s diet should be high-quality grass hay like Timothy or orchard grass. Hay is important because it has the vitamins and nutrients a guinea pig needs. It also serves to wear down the piggy’s constantly growing teeth through constant chewing. Guinea pigs should have access to hay at all times.

Next up, guinea pigs should get a small amount of healthy pellets. The standard rule is about 1/8 cup of pellets per guinea pig. You want a pellet that is Timothy-based for adult piggies (over 6 months old) and it shouldn’t have any added nuts, seed, or colorful pieces thrown in. One of the best guinea pig pellets on the market today is the Oxbow Garden Select Adult Guinea Pig food – this is what I feed and I highly recommend it.

Like all animals, guinea pigs should have access to fresh, clean water at all times. A bowl or a bottle is fine, whichever works better for your guinea pigs.

Finally, let’s talk veggies. A guinea pig needs about a cup of fresh veggies per day. Vegetables provide the additional vitamins a guinea pig needs, especially vitamin C. If they don’t get enough vitamin C guinea pigs can develop a health issue called Scurvy.

Guinea pigs are not able to produce their own vitamin C, so as their owners we have to make sure they are getting enough through their food. Many veggies have vitamin C, which luckily makes it pretty easy to be sure your piggy is getting enough.

Now that you have a basic understanding of the proper guinea pig diet, let’s take a deeper dive into veggies.

Guinea Pig Veggie Basics

Now, let’s dive a little bit deeper into feeding veggies for guinea pigs. Providing a variety of vegetable options on a regular basis helps make sure your guinea pigs are getting a variety of nutrients while also keeping them interested in their food.

Not all vegetables are safe or healthy for guinea pigs, so it’s important to be aware of what you are feeding. The main things to consider when choosing veggies for your guinea pigs is the calcium and sugar content of each vegetable.

You don’t want to be feeding your guinea pigs too much calcium or too much sugar. Too much sugar can cause your guinea pig to get fat. Too much calcium can increase the risk of bladder stones, which can be a major health issue. Bladder stones are extremely uncomfortable for the piggy and can even require surgery to remove, so being aware of calcium levels is important.

If this seems overwhelming, don’t worry! I’ve made it easy for you. While there are several veggie charts you can find online, they usually contain quite a bit of information and can still be overwhelming for a new owners trying to figure out what to feed.

I’ve put together an easy to follow veggie list you can download for free that lists safe vegetables that can be fed on a daily, weekly, and occasional basis. It even has a sample weekly meal plan!

Can Guinea Pigs Eat Lettuce?

So now, to answer the question: can guinea pigs eat lettuce?

Yes! They can.

However, not all lettuce is created equally. There are different types of lettuce and not all of them are suitable for guinea pigs. The different types have different nutrients that affect whether they are a good option for your piggy.

Iceberg lettuce is the only type of lettuce that really shouldn’t be fed to guinea pigs at all. It doesn’t have much nutritional value and is mostly water. Too much of it can overload your piggy with too much water and cause diarrhea. This can actually be dangerous to your piggy’s health, so avoiding iceberg lettuce is your best bet.

The Best Type of Lettuce for Guinea Pigs

Although iceberg lettuce isn’t a great option, there are many other types of lettuce that you can feed your guinea pigs.

First up, we have red leaf and green leaf lettuce. These are pretty similar nutritionally, they are just different colors. Leaf lettuce is safe and healthy to feed on a daily basis and is usually available in most grocery stores. This makes it a great staple vegetable for your guinea pigs.

Another option is romaine lettuce. This is another good staple lettuce option that is safe to feed every day. It is also easy to find in grocery stores and most guinea pigs seem to enjoy it.

Some people have reported that they have seen an increase in calcium sludge in their guinea pigs’ urine after feeding romaine lettuce. If you are finding thick, chalky white spots in your guinea pigs’ cage after adding in romaine you may want to limit it to only once a week.

When it comes to the pre-made salads and spring mixes you can find in the grocery store, whether they are a good option really depends on what is in them. Many of them have things like spinach and arugula mixed in which are not suitable to be fed every single day. These types of mixes can be good options to rotate in every few weeks to provide your guinea pigs with more variety.

You don’t want to be feeding any pre-made salad that has things like egg, cheese, cabbage, or seeds mixed in as these things are not safe to feed your guinea pigs.

Final Thoughts on Feeding Lettuce to Guinea Pigs
