We never fed Jack pellets, we just gave him a wide variety of fresh fruits and vegetables, using the House Rabbit Society list of safe foods. He wouldn't eat the pellets, so we skipped it. He lived a very healthy 8-9 years, and his death was unrelated to diet.
This. Commercial rabbits pellets are a evolution of the food they were fed when they are raised for meat. Rabbits with healthy teeth actually benefit from a pellet free diet, the majority of their daily intake should be from timothy or meadow hay and this can be supplimented with fresh herbs, rabbit safe veg and alfalafa hays and redigrass. It's very common for domestic rabbits to be overweight and this can be caused by the food you buy in pet shops and is very detrimental to their health.
