from my research on them when they are a year old you only give them limited pellets it was not much, but from the feeding schedual, it had pellets for the morning meal and greens for the evening meal, greens should be fine once they are a year old, well thats what I read in several places but I am not that bunny experienced yet my question is why is there carpet in his cage?? I just put runner mat on the bottom of karis pen because it gives her grip, and its easy to clean, and its cheap, all ya gotta do is take out the runner mat wipe it down with viniger water, and dry it off and put it back on the floor.
