what nutrients do adult rabbits require?
Once rabbits are full grown, they donât need to put on more weight. Feed your pet a commercial pellet that is designed for the maintenance of the adult rabbit, with a fiber content of 18% or higher, a protein content at around 13-14% and fat content at no more than 3%.uinea pigs are herbivores and require a similar diet as rabbits with plenty of grass hay and greens and limited commercial pellets. They have continuously growing incisors and molars, which like the rabbit wear down with the normal action of eating.
