Feeding rabbits pure clover hay can be acceptable as part of their diet. Clover hay is generally safe for rabbits to consume and can provide them with some nutritional benefits. However, it's important to keep in mind that a balanced diet for rabbits should consist of a variety of hay types, such as timothy hay, orchard grass, or meadow hay.

Clover hay can be higher in protein and calcium compared to other hays, so it's important to offer it in moderation. Rabbits have specific dietary requirements, and their digestive system is sensitive, so it's important to provide a balanced and varied diet to ensure their health.

If you choose to feed clover hay to your rabbits, it's recommended to introduce it gradually and observe how your rabbits react to it. Monitor their digestion and overall health to ensure they tolerate it well. If you have any concerns or questions about your rabbits' diet, it's always a good idea to consult with a veterinarian who is knowledgeable in rabbit care.
