My buns were used to an alfalfa based pellet and hate Oxbow. What I have done is mix 3 pellets together... Kaytee timothy pellets, Kaytee Supreme and Exact. I still think they leave the timothy ones. I have heard about Marten pellets (high fiber, low protein?) and found a place near me that sells them. Would Marten pellets alone be better than what I am doing? There are two green bags which is the correct one.? Are Marten pellets really that good. I have one overweight bun and one with too many cecals. Thanks
