Teacup bunnies, or Netherland dwarf rabbits, require a diet consisting of vegetables, hay, water and pellets. Due to their smaller size, their gastrointestinal systems are more delicate than other rabbits, and must be fed with care. A minimal amount of fruit is also recommended due to the high sugar content in fruits.

Teacup bunnies require high amounts of fiber in their diet. Brome or Timothy hay is a great source of fiber, but rabbit owners must ensure the hay's cleanliness. Not only does hay provide fiber, but it also provides rabbits with the opportunity to keep their teeth healthy and ground down.

Rabbits should receive at least two cups of leafy greens a day. These can include the tops of carrots and beets as well as kale, parsley and mint. Non-leafy vegetables that rabbits can eat include bell peppers and broccoli. No matter which vegetables rabbits eat, owners must ensure that the vegetables are clean and preferably organic.

Any pellets fed to rabbits must be made for rabbits only as many rodent pellets include seeds and nuts which rabbits can't properly digest. Rabbits less than six months old can have an unlimited amount of pellets, but after that pellet intake should be reduced to two or three ounces per day.

Any changes to a teacup bunny's diet should occur slowly due to their fragile digestive systems.
