Biologically Appropriate Raw Food, or ‘BARF’ for short, is a complete and balanced raw diet for cats or dogs, which consists of raw meat, offal, raw bones and - in the case of dogs - vegetables. It should contain the full complement of essential healthy vitamins, minerals and natural oils they need. What they would eat in the wild - meat, bones, bits of vegetation - is what they are built to consume and digest. Fresh raw food is as close to this natural diet as possible and is therefore easy on their digestive system.
