 When I have patients talking about their cats and their dogs, they can't get up on the couch anymore. They have to lift them up. They can't jump up to whatever they used to be able to jump up at. And I say, well, do you feed them raw food or do you feed them cooked foods? Well, I just feed them kibbles. That's cooked food. What they need for healthy hip joints is not in that cooked food. So their joints are going to waste away to where they can't jump up on the couch. Start feeding them raw food and watch what happens.
