All pets have their place, behaviors, and needs. You cannot give a cat’s scratch post to a dog. Similarly, you cannot give a dog’s chew toy to a cat. Both animals have their favorite things.
However, if two pets live together, they can develop similar interests and behaviors. Hamsters and bunnies are small, cute, playful, and can become good friends. They can share veggies and fruits. However, can rabbits eat hamster food?
Rabbits cannot eat hamster food. Rabbits require specific foods and a balanced diet for their sensitive stomachs and immune system. You need to feed your rabbit hay, greens, and fruits for a healthy life for your rabbit.

Why is Hamster Food Unsuitable for Rabbits?
Hamsters are omnivores, whereas rabbits are herbivores. A food designed for hamsters has qualities to meet the nutritional needs of an animal that eats both meat and vegetables. Rabbits do not need that. As grazing animals, rabbits have their own digestive needs.
Rabbits are sensitive creatures. Even the slightest imbalance in their diet can cause them to feel stressed and get sick. Rabbits are not supposed to eat rabbit pellets too much, let alone hamster pellets. As plant lovers, a rabbit’s daily diet should contain fresh things, not processed ones.
Rabbit food is very different than hamster food because both animals have different needs. Each of their pellets is designed specifically for each animal.
Comparison of Nutritional Needs of Rabbits and Hamsters

Rabbits and hamsters have different bodies, immune systems, and nutritional requirements. Their foods are designed keeping those values in mind. A hamster needs a low-fiber high-fat diet, and a bunny requires a high-fiber, low-fat diet.
Here are the nutritional needs of the two animals on a daily:
- Rabbits need 18-22% fiber, 14-18% protein and 0-3% fat.
- Hamsters need 10-14% fiber, 15-18% protein and 6-12% fat.
As you can notice, both pets require specific amounts of certain nutrients. It is evidence that hamster food is not suitable for your furry rabbit.
What will Happen If You Feed Hamster Food to Your Rabbit?
Rabbits are fragile pets. The littlest of things can disrupt your precious pet’s peace. If your bunny eats something wrong, it will suffer through digestive issues that will damage its organs. Furthermore, when a bunny suffers physically, its mental health also beings to deteriorate.
Hamster food can harm your pet rabbit in many ways. A few are mentioned below:
Fatty Liver Disease
The high content of fat present in hamster food can cause liver issues for your rabbit. Bunny’s body cannot digest such a high amount of fat, resulting in its accumulation in the liver.
Your precious rabbit will show the following signs if it is developing fatty liver disease:

- Unusually less fecal excretion

- Depression
- Lethargy
All these symptoms will be easy to notice as bunnies are hyper and get zoomies often. If your rabbit is slow and tired, you should get it to the vet for a fatty liver test.
Gastrointestinal Stasis
Rabbits require a good amount of fiber in their diet for healthy bowel functioning. Hamster food has very low fiber content because hamsters do not need too much fiber.
If you give it to your rabbit, your bunny’s gut bacteria will react and get disrupted. It will cause your furry friend to experience painful gas. If this lasts, it can cause organ failure and be fatal for your pet.
There are some signs to look out for if you suspect GI stasis:

A low intake of fiber can result in serious health issues for your rabbit. If you notice any symptoms, go to the vet immediately.
Obesity

Obesity also puts stress on your rabbit’s heart and mind. It can cause damage to its internal organs.

How Much Hay Should You Feed Your Rabbit?

Hay is rich in fiber and essential for your rabbit. It should be a bigger portion of your rabbit’s daily diet. Many people say you can give unlimited hay to your pet, but it is better if you give 80-90% of hay and mix it with other foods to give your rabbit a balanced diet.
Hay is the least risky food for your rabbit because they are grazing animals. They were born to eat all sorts of things that grow in the soil. Hay is not only good for your rabbit’s gut, but it is also beneficial for your bunny’s ever-growing teeth as it helps trim them. Add hay in every meal you give your pet and in the majority. There are no side effects to eating too much hay.
