Our rabbits' diet doesn't include pellets and we know they need salt and minerals. We've been using chunks cut from a block we bought for our goats. Zach bored holes in the chunks and hung them from the tops of cages so the salt wasn't touching any of the cage wire. Need to make a new batch soon and he wanted me to ask if anyone has a good way of boring a hole through salt block (he said it was really slow with his drill) And there are rusty patches above where the chunks hang. Maybe because the rabbits push the chunks up against the wire as they lick them? Anyway I'm hoping someone can tell me what they've figured out for offering salt and mineral that is easier than what we've done and doesn't rust the cage.
