Bunster is about 6 months old now. Do I have to switch her from alfalfa to timothy pellets? Unfortunately I bought a huge bag of alfalfa pellets and I'd like to keep using them if it's okay. I think Bunster is starting to get a bit overweight though, so I will at least decrease the amount of pellets I'm giving her but I wonder if I can keep her on alfalfa. The bag says it's for rabbits up til 1 year old, but Holland Lops reach adulthood faster than bigger rabbits.
