I've heard great things about that too. Just mixing up some coconut oil or lard with their food has a remarkable effect on their health. Amazing what nature provides, and scary what is kept from us or what untruths we are led to believe.i.e. Banting or the Tim Noakes diet
I have also seen how well Golden Paste (turmeric, coconut oil, ground pepper) works. I successfully treat my horses and doglets, one with an extremely sensitive tummy, together with apple cider vinegar and ceyenne pepper. Good muti that.
