Look what I found on Etherbun after a little search
We had this discussion not too long ago, so to reiterate (as I remember it) the concensus was that the salt/mineral licks are not needed and can be harmful to the bunny's health. Pixel LOVED the Apple mineral lick, but Rami said it wasn't healthy (the "mineral" in it is calcium) so, I immediately removed it. Pixel's still mad at me even though I keep telling her that it's Rami's fault! And, I will confess that
she's no longer as "bloated" looking as she was .
So, don't waste your money. The rabbits never pout at Rami, they consider him to be their Paladin! debbie http://tech.groups.yahoo.com/group/etherbun/message/106353 Re: [EtherBun] salt and mineral licks If you feed good quality pellets and grass hays, there should be
no need for extra minerals or salt, in fact those wheels sometimes contain
crap harmful to bunnies . Neither do you need to put anything in the water. http://tech.groups.yahoo.com/group/etherbun/message/104340 Re: [EtherBun] lick salt Salt licks are basically crap. They aren't needed. The only thing they do it make the buns thirsty and drink more water, making you buy more water bowls and water bottles from the same companies that make the salt licks. Buns do fine with plain pellets, plenty of hay and fresh veggies and water. http://tech.groups.yahoo.com/group/etherbun/message/75666
While I found loads of posts saying they were not needed I did not find one (out of over 100 I read about salt licks) that said they were needed.
