My bunnies get fed a big pile of hay everyday & by the following day most of it has gone. Hay is a very important part of a rabbits diet. In fact it should make up the greatest percentage. Hay helps to keep a healthy digestive system & also helps to wear their continually growing teeth down.
Tilly is currently on a dust free meadow hay because of her partner Rumble who has an allergy to dust.
As a general rule I give each rabbit a pile of hay as big as themselves. However, for some that isn’t enough so I will increase it & then there are those of the bunnies who eat it but aren’t that bothered. Rumble for instance is a good hay eater but just doesn’t eat as much as everyone else.
