Can Guinea Pigs Eat Rabbit Food?

Guinea pigs and rabbits have some similarities, even if they are both different in other aspects. Sometimes pet owners prefer to have both of these the two animals since they are really just so cute. But what about their diets? Can they share the same type of food?

So, can guinea pigs eat rabbit food? Unfortunately, guinea pigs cannot eat rabbit food for several reasons. However, the opposite is true, the rabbits can eat and enjoy guinea pig’s food. You are probably wondering why guinea pigs can’t feed on the same foods eaten by rabbits when both of them are vegetarians, right? While both animals eat veggies and fruit, guinea pigs need foods that offer a substantial amount of vitamin C because the guinea pigs can neither create nor store this vitamin on their own, and that is why they need an external source for it.

Vitamin C is vital to the lives of cavies, and this is due to the roles it plays. For instance, this potent vitamin helps to maintain a steady and robust immune system for the guinea pig. This vitamin ensures that your pet has received all the necessary nutrients. A healthy guinea pig will live a good and long life.

Rabbit foods may be detrimental to the life of your guinea pig and can even lead to dire consequences. The diet that you should use for your guinea pig is very specific, and for this reason, anything out of the box may lead to significant health risks and concerns. For more on the potential risks that guinea pigs can have from eating rabbit food read the section below.

Risks to Consider When Feeding Rabbit Food to Guinea Pigs

Giving your guinea pig rabbit food does not only deny it vitamin C, risking its immunity but also has additional risks like the ones below:

  • Choking Hazard

Some rabbit foods present a potential choking threat to guinea pigs. Foods such as seeds and nuts can cause your cute little pet to choke and if not handled properly, can cost the life of your guinea pig. Cavies naturally don’t feed on seeds and nuts simply because of this reason. The passage of food for rabbits and guinea pigs differs.

  • Allergic Reactions

Guinea pigs don’t have a robust immune system and are thus prone to diseases and infections, including allergic reactions. These are brought by foods that do not go well with their digestive system. Some rabbit foods can lead to allergic reactions in guinea pigs. This can present through vomiting or even diarrhea and can affect how your pet feels. In case you notice anything that is not normal in your guinea pig, you can offer your guinea pig a lot of water and later simply avoid that food. If the situation worsens, then you need to visit a qualified vet for assistance.

  • Too Much Fat and Protein

Some foods that rabbits eat have excess fats and proteins in them. These two nutrients are essential but not needed in large portions. Unfortunately, the consumption of foods that have too many fats and protein can jeopardize your guinea pig’s health and cardiovascular strength. Besides, you don’t want your guinea pig to grow so big through gaining unnecessary weight after consuming foods that are rich in excess fats and protein. You should have a guinea pig that has a balanced weight which also contributes to its well-being and health.

  • Illnesses and Defects

Due to the absence of several nutrients in rabbit foods, the consumption of this by guinea pigs opens up an avenue for both diseases and deformities. For instance, scurvy is one illness that will be experienced when your guinea pig is on a rabbits diet plan. This illness is caused by a vitamin C deficiency in its body. Another problem or defect that your guinea pig may experience by eating rabbit food is stunted growth, especially for the bones. A gap in calcium levels opens up a risk of poor bone structure and growth. In some cases, rabbit food lacks vitamin K which is vital for the synthesis of calcium.

  • Presence of Antibiotics

Some rabbit foods have antibiotics that can harm guinea pigs. This is a big deal. There are several types of antibiotics, but the most popular one is the penicillin-based antibiotic that is very harmful to guinea pigs. If not taken care of, it can lead to death for your pet. This is something you don’t want to witness. You can prevent all of this by not feeding your guinea pig the rabbit food.

  • Some Rabbit Foods Destroys Beneficial Bacteria in Guinea Pigs

Although not all, some of the foods that rabbits eat, when given to guinea pigs, can lead to the clearance of vital bacteria in your pet. Guinea pigs depend on certain bacteria found inside the stomach for essential purposes and roles in their lives. For one, these bacterias help the guinea pig to digest food since cavies have a weak digestive system that cannot digest foods on their own. Another reason why guinea pigs need these bacterias is to extract nutrients from food, something that they find hard to achieve independently.
