more exercise and less food. Try the Atkin's diet for rabbits.

Be sure you have the proper nutritional mix for their food, and don't feed them too much. They will grow to be their natural size, no matter how little you want them to be. Check with your vet to be sure the feed you are using is good, and what portion they need.

By feeding them correctly for their age and actively level. If they are just a pet rabbit, most of their food should be good quality hay and veggies (2 cups of leafy green veggies per 6 pounds of their bodyweight). A none breeding rabbit doesn't need pellets. The good veggies are (Add one vegetable to the diet at a time. Eliminate if it causes soft stools or diarrhea) : Alfalfa, radish & clover sprouts Basil Beet greens (tops)* Bok choy Broccoli (mostly leaves/stems)* Brussels sprouts Carrot & carrot tops* Celery Cilantro Clover Collard greens* Dandelion greens and flowers (no pesticides)* Endive* Escarole Green peppers Kale (!)* Mint Mustard greens* Parsley* Pea pods (the flat edible kind)* Peppermint leaves Raddichio Radish tops Raspberry leaves Romaine lettuce (no iceberg or light colored leaf)* Spinach (!)* Watercress* Wheat grass (!)=Use sparingly. High in either oxalates or goitrogens and may be toxic in accumulated quantities over a period of time

90% of a rabbits diet is HAY, not alfalfa, but Timothy hay, they should have hay at all times, limit the pellets to 1 teaspoon to up to 5lbs, and 1 tablespoon for 6lbs. and up. Pellets are the food that make rabbits fat. Hay and good green veggies is all they need, keep the veggies at a portion control too. For more info, rabbit.org

When you are feeding your rabbit pellets, make sure it's an all-natural, original mixed pellet and contains NO treat or seeds or dried fruits. I was even told by a pet store employee that these are no good and she asked me not ever to buy them! Why? because these things add fat and extra sugar which makes rabbit gain weight. My recently 3-month old adopted rabbit's diet is consisted of original mix rabbit pellet (by Hagen), Timothy Hay and some dark leafy greens such as parsley. I was asked to give him carrots as an occasional treat since they are high in sugar. Also, make sure you let your rabbit out of the cage for 2-4 hours of exercise because it's crucial for their physical and mental health. Rabbit don't usually need a fancy diet or stuff like that the way some pet stores make it out to be. Just make sure you give them an unlimited supply of Hay, water and a balanced diet and excercise. If your rabbit is younger than mine then maybe should be on an Alfalfa Hay diet since they need more calcium but make sure you ask the person in charge. You can buy a net that will keep your rabbit within a certain area and let him hop around there. Protect the area with cardboards or newspapers to avoid things like urine stain. Also do your research, ask questions to vets and fellow rabbit owners! If you take my advice, It's WAAAYY better to adopt a rabbit than to buy one because at pet stores, they don't really take care of the animals the way they do at Humane Societies. I find mine to be very involved and caring towards the animals and friendly and helpful towards me!
