The digestive tract of a rabbit has been created particularly for this diet. The grasses’ long fibers keep your rabbit’s digestive system going.

Here are our ideas for feeding your rabbit the proper way, every day, with your rabbit’s health in mind:

  • The most significant feeding source for a bunny rabbit is fresh hay. Not only does the fiber keep your rabbit’s digestive tract moving, but all of that beautiful nibbling keeps rabbit teeth from growing overgrown. Always have fresh rabbit hay on hand.
  • Rabbit food of superior grade. Because various manufacturers recommend varying serving sizes, check the label to discover how much rabbit food your bunny should consume daily. Some of my favorites include pumpkin seeds, unsalted pepitas, and sunflower seeds.
  • Clean, fresh water – at least once a day, take time to rinse and replenish your rabbit’s drinking bottle. Your rabbit requires water 24 hours a day, seven days a week.
  • A cup of fresh leafy greens for two pounds of body weight of your rabbit, plus a few crunchy veggies to nibble. Fruits and vegetables are natural delights. 
  • Limit your rabbit’s fruit intake to around a teaspoon per two pounds of body weight.
