Please be careful feeding foods with high salt or sugar content in, such as Weetabix, as it can play havoc with a rabbits guts.
We nearly lost a rabbit who ate Weetabix as the cereal expanded in the gut and causes gut statis.
The simpler the diet the better for bunnies, although you find the occasional rabbit who will tolerate cereals on the surface, but it is what the salt and sugar is doing internally that worries me.
