Here, there are hardly any brands that are pure pellets. The rest have all this other stuff (can't remember what, will check when I can). Are just pellets better? What is the best diet for a bunny? And I've never heard grass mentioned anywhere. We give heaps of grass to the bunnies as well as the rabbit food mix and veggies. The rabbit food here is usually for both rabbits and guinea pigs (even though they eat different food) so it's probably catered more to guinea pigs? I think I might buy pellets next time, I think it's more expensive though.
