what type of hay for rabbits
Timothy Hay is by far the most popular and probably the best kind you can give your rabbit as their basic hay source. Timothy hay is a good all-around choice for unlimited offering to your rabbit. Timothy hay is a mix of leaves and stems from Timothy grass, which is a perennial bunch grass.
Alfalfa (Lucerne), is actually neither hay nor grass! It is in fact a legume and is also grown as a richer type of animal feed. Alfalfa hay has a much higher protein level than grass / hay, which makes it very fattening to feed as a main ingredient for an average adult rabbit.
