Can rabbits eat sunflower seeds, and why?
Sunflower seeds are best avoided for rabbits. Too high in fat and can contribute to obesity; offer hay and greens instead.
Rabbits are herbivores: roughly 85% of their diet should be good-quality hay or grass, plus a daily handful of leafy greens, with only small amounts of other veg and tiny occasional fruit. They have a sensitive hindgut that depends on constant fibre — sudden changes, sugar or starch can trigger dangerous gut stasis and bloat.
