I wouldn't suggest having the pellets as mainfood. Pellets aren't really needed in a rabbits diet, just some addednutrients/ fiber. I wouldn't suggest having pellets as the main source.I'd have hay as the main source (a rabbit needs lots of fiber), thennext grass and greens (I'd stick with the grass, btu the vegetablesaren't very necassary, just think of them as more of a treat), and thenpellets. Too many pellets can lead to obesity and an unhealthy rabbit.
Hay is the MOST important thing you should feed a rabbit. Pellets should only be givin maybe 1/4 of a cup, not much.
