Can rabbits eat rits crackers?

You should avoid feeding rabbits anything other than a diet that they could receive naturally in the wild. i.e a diet of lots of hay and fruit/veg. So although feeding rabbits digestive biscuits/weetabix may not kill the rabbit, it's also not very good for them (they need hard food that take lots of chewing to maintain healthy teeth). Plus rabbits can gain weight quite easily when overfed.
