Rabbits will graze nonstop throughout the day. It is essential to provide your rabbit with constant access to both hay and veggies so that they can chew and eat. It is possible that a rabbit’s health would suffer if they go without food for a full day. If your rabbit weighs less than ten pounds, they need approximately a 14 cup of pellet food each day. Rabbits weighing more than ten pounds should need even less since they should be consuming hay and vegetables as their main source of nutrition.
