Ham is pork that has been preserved by either curing it or bringing, smoking or salting it. Traditionally it is made from only the hind leg of a pig and is referred to that specific cut of pork.
So can rabbits eat ham at all?
Unfortunately they cant at all. Rabbits are unable to eat any kind of meat as they are herbivores. So they may nibble at it, but that is all and will avoid eating it. So dont waste of your ham on bunnies as they wont eat it.
