What to Feed Guinea Pigs When Out of Food: 9 Replacement Food for Pet Cavies

Guinea pigs are intelligent and can survive on a limited diet of hay and pellets. If you are out of these food items, be sure to provide your guinea pig with the replacement foods such as grass types, lettuce, bell pepper, and cauliflower. In addition to food, guinea pigs need water and fresh air to stay healthy.

When You Are Out of Guinea Pig Food


When guinea pigs are out of food, their priority should be to find hay. It should be the main component of their diet, with a small number of fresh vegetables added.

Guinea pigs will eat anything in front of them – so make sure to have plenty available at all times! Constantly water your guinea pig and rotate their hay for optimum health.

Without Hay

Guinea pigs will stop eating if they don’t have enough water or hay available. They can go for up to 24 hours without grass. When out of hay, guinea pigs can survive on food such as fresh vegetables and fruit.

Make sure to provide a variety of foods to avoid boredom and nutritional deficiencies. Monitor your pet’s weight and appearance regularly to ensure proper nutrition.

Without Pellets

If you’re out of pellets for your guinea pig, don’t panic. Guinea pigs are herbivores, meaning they will eat various plant-based things when out of food.

Usually, guinea pigs don’t go long without food when given the proper care. If you cannot get pellets for them, make sure to have some fresh fruits, vegetables, or hay for them to gnaw on. If all else fails, give them water and let them explore their new surroundings (if you’ve set up a habitat).

9 Replacement Food to Feed Your Guinea Pigs When Out of Hay

Giving them a high-quality substitute is essential when your guinea pigs are out of hay. This can be fresh vegetables or fruit or a mixture of fresh vegetables and fruit.

1. Fresh Grass From an Untreated Lawn

When guinea pigs are out of food, fresh grass from an untreated lawn can be an excellent substitute food. Always ensure that no harmful items are included – some feed might contain grains, seeds, or nuts that aren’t good for guinea pigs’ diet.

When giving them fresh grass from an untreated lawn, ensure it is wet so they don’t get sick. Beware of feed that has grains in it – these will not provide your guinea pig with the nutrients they need and could lead to health problems.

2. Wheatgrass

Wheatgrass is a great replacement food for guinea pigs as it is high in fiber and contains vitamins A, C, and E. This makes it ideal for helping to regulate your guinea pig’s diet and maintain overall health.

Additionally, you can mix wheatgrass with other hay replacements like oat bran or alfalfa to give them the necessary nutrients. So make sure you have a supply on hand to top up their needs.

3. Cat Grass

Guinea pigs are active and playful animals that need a lot of stimulation to keep them entertained. A good option is to give them different types of food to eat, as well as fresh green beans or cat grass for hay replacement.

4. Pellets That Contain Timothy Hay

Pellets that contain timothy hay are the perfect food for guinea pigs when grass isn’t readily available. Pellets can be custom-made according to your guinea pig’s diet and health requirements, ensuring they get all the nutrients they need without having to eat hay constantly.

This is a great way to keep them healthy and content and reduce their caging requirement. Make sure you check the ingredients before buying, however – some pellets may have unhealthy additives or fillers, which could potentially harm your guinea pig in unexpected ways.

5. Lettuce

Lettuce is an excellent option for guinea pigs as it has few calories and provides essential nutrients. Some examples of lettuce you can feed to guinea pigs are romaine lettuce, iceberg lettuce, endive, watercress, etc. Fresh vegetables will suffice if you are out of hay or your guinea pig doesn’t like grass.

6. Sweetcorn

Sweetcorn is another good food option for guinea pigs as it contains less sugar than other options and offers a good source of vitamins and minerals.

7. Kale

Kale can also be fed to Guinea Pigs as it is high in fiber which helps with digestion and provides essential nutrients such as vitamin C.

8. Bell Peppers

Bell peppers are one of the most popular vegetables in the world and come in a wide range of colors, shapes, and flavors, making them perfect for all sorts of meals.

However, feeding your guinea pigs only a few bell peppers is essential, as this can harm their health. Keep a close eye on their weight and provide them sparingly if they seem thin or malnourished – bell peppers are high in vitamin C, so feeding them too much can lead to scurvy.

Try giving them different types of fruits and vegetables as replacement food; bell peppers work best when paired with other healthy foods rather than being the only source of nutrition.

9. Cauliflower

Cauliflower is an excellent addition to guinea pig diets as it is high in vitamin C and provides them with plenty of fiber. In addition, it is an excellent source of vitamin K2 and antioxidants.

Make sure to soak the cauliflower in water before feeding it to your pet, as this will ensure they get all the nutrients they need. Additionally, check with your vet before introducing other vegetables into their diet – guinea pigs are susceptible animals, and some vegetables can cause health problems if not consumed in moderation.

What Not to Feed Your Guinea Pig

Knowing what to feed your guinea pig when you’re out of food can take time and effort. However, following a few simple guidelines will help you maintain a healthy diet for your pet.

Guinea pigs should not be fed meat, eggs, dairy products, or grains. Instead, they should primarily eat plants. Make sure to provide them with fresh vegetables and fruits daily to get the nutrients they need.

If your guinea pig is having trouble eating or refusing food, it may be because of allergies or other health problems. In that case, consult your veterinarian to determine the best course of action.
