I know that Oxbow Organic Rabbit Pellets list Organic Grass Hay as the first ingredient, as opposed to most pellets which either list timothy or alfalfa. But grass hay could mean just about any hay other than alfalfa. And it may be that they include a variety of grass hays. You could try contacting Oxbow and asking what they mean by grass hay and if the pellets ever contain timothy.
