The short answer
A suitable grass hay that can be offered freely to most adult rabbits.
Recommended amount
Offer freely when it is a proven, clean grass hay; fresh local forage needs gradual introduction and varied fibre sources.
Suitable rabbit age
Age and health needs vary. Young rabbits and adults may require different hay choices; ask a rabbit-experienced veterinarian.
Preparation
Wash well, identify correctly, serve plain and raw unless the guide specifically says otherwise, and introduce gradually.
Parts or forms to avoid
Discard damp, dusty, mouldy or contaminated hay.
Nutritional and feeding notes
Long fibre supports normal chewing and gut movement; exact quality varies by species, harvest and storage.
