MN asks: “Is there anything wrong with taking the family pet to a holistic vet? Our cat has had bladder problems in the past, and we are buying special food for him from the vet, but he has put on weight and we would rather consult with a vet who can recommend a homemade cat food recipe that is less expensive and healthier for him. We have had a history with our pets getting cancer, and we are concerned that commercial pet foods may be partially responsible.”
