As an example, a rabbit could have 1 egg cup of pellets and a pile of hay per day, plus a selection of vegetables. One day it might be a cauliflower leaf and fresh basil/parsley and another day blackberry leaves, fresh grass and a small carrot.
Homemade rabbit treat! Frozen fruits and veggies! Just cut up favorite treats into silicone mold then fill with goodies and water then freeze overnight. Great thing to keep bunnies cool during the summer!
