I do not like Kaytee and LM, since it doesnt have what a bunny needs. Hope this helps you. If your bunny is 7months+, the best pellets are the Timothy based one. The best one I have found is the Oxbow Timothy based pellet. Those are the pellets with the highest Fiber content (28%). If you cant get that brand, then when you chose, make sure that the Fiber is higher than Protein and that fat content is lower than 3% or 4%. The Oxbow was getting too expensive for me since I have to order, so now my bun is on "Martin" brand for Adult Rabbit. That one is not as good as Oxbow but still Tymothy based, Crude Protein 15%, Crude Fiber 18%-22%, Crude Fat 2.5%.
