Owning a pet rabbit can be great fun. They are a very cute and loveable animal. But you need to understand exactly how to feed and care for your pet in the right manner to prevent sickness and disease form becoming a problem. One of the biggest considerations is what type of rabbit food to give to them.
Rabbits are naturally herbivores, this means that they only consume plants, so do not give them any scraps of meat from the kitchen table, save that for your pet dog. Most bunnies would enjoy eating herbs, grass, seeds, and vegetables. It is also possible to provide them with special rabbit pellets designed to ensure they have the maximum nutrition possible, if this is an option you are going to undertake then make sure the pellets you choose are correct for the age of your rabbit.
Understand that just like us humans, each rabbit with have its own particular likes and dislikes. For example, one individual may have a soft spot for carrots whereas another may prefer munching on lettuce leaves. If you are to give them an assortment of vegetables then it would be better to choose organic varieties rather than those that have been coated with high amounts of pesticides. A rabbit is not going to care over how its food looks; it is the taste and nutrition which is important.
You should avoid giving any food that is overly watery or sugary as this can have a negative impact on their digestive system. If you notice that your pet is not so inclined to eat the foods you are providing then change their diet.
It is also important that the rabbit can consume foods that need chewing. This helps them to maintain a healthy oral cavity and prevent gum infections and related diseases.
