Rabbits have a huge amount of taste buds (17000 compared to only 9000 in humans) so they enjoy a wide range of different foods, but the main component of a rabbit’s diet (at least 80%) should be good quality fresh meadow hay/grass. The rest of the diet should be made up of a variety of vegetables some fruit, herbs and flowers. Rabbit pellets can also be fed to your pet but must not make up the main part of the diet.
Some vegetables such as radish tops, spinach and mustard greens contain oxalates and should be fed only occasionally and some vegetables such as endive, broccoli and cauliflower can cause gas and make the rabbit very uncomfortable. New foods should be introduced in small amounts and slowly so you can judge how that food is accepted.
Rabbits that should always eat constantly and detecting an illness sooner rather than later can be the difference in whether it survives or not. It’s a good idea to feed your rabbit a wide variety of foods and have definite treat foods, that way you will know immediately if there is a problem.
Gastrointestinal disease and dental problems are the main illnesses that are commonly seen by vets that can be attributed to incorrect diet. If either of these problems are suspected you should take your rabbit to the vet.
