Should I use Timothy Hay or Alfalfa for bunnies?
Young rabbits (under a year): Feed unlimited alfalfa pellets along with a mixture of timothy and alfalfa hay available at all times. Start introducing veggies very slowly and carefully at 3 months of age, and gradually increase the amount of veggies and decrease the amount of alfalfa hay as the rabbit approaches one year of age. Mature rabbits (one year to seven years): As the rabbit approaches one year, slowly decrease the amount of pellets fed until the rabbit is eating approximately one fourth of a cup per five pounds of body weight. Consider gradually switching to timothy pellets rather than alfalfa pellets. Eliminate alfalfa hay and feed free choice timothy hay. Continue to increase veggies, especially leafy greens, until the rabbit is consuming approximately 1 cup per five pounds of body weight. From: http://www.petinfopackets.
