Rabbits are herbivores and have a diet that is primarily composed of hay, fresh vegetables, and rabbit pellets. Here are some more details about what rabbits eat:

1. Hay: Hay is the most important part of a rabbit's diet and should make up the majority of their food intake. Choose a high-quality grass hay, such as timothy or orchard grass, and provide your rabbit with unlimited access to it.

2. Fresh vegetables: Rabbits also need fresh vegetables as part of their diet. Offer a variety of leafy greens such as kale, parsley, cilantro, bok choy, and romaine lettuce. Avoid feeding your rabbit starchy vegetables like potatoes or corn, as well as beans, onions, or iceberg lettuce which can be harmful to their health.

3. Rabbit pellets: Pellets are a good source of nutrients for rabbits, but should only make up a small part of their diet. Choose a high-quality rabbit pellet with a high percentage of fiber and a low percentage of carbohydrates.

4. Water: Fresh, clean water should be available to your rabbit at all times. You can provide water through a water bottle or a water bowl.

It's important to feed your rabbit a balanced diet and avoid feeding them human food or treats that are high in sugar or fat. Providing your rabbit with a variety of foods and plenty of fresh water will help keep them healthy and happy. Additionally, always introduce new foods slowly and watch for any signs of digestive upset or allergies.
