It took my cats several months to get used to a raw meat diet and now they prefer raw over canned. A local holistic veterinarian sells raw dog and cat food and it's got all the nutrients the cats need. I supplement this food with raw liver, hamburger and stir fry beef whenever I thaw it out for my family's supper and the cats just vacuum it up. I have had no problems with them experiencing any digestive or intestinal ailments because I no longer give them poisonous dry cat food. What do farmers give cattle to fatten them up for slaughter: grain and corn. Most commercial dry cat foods contain mostly corn and grain. Very bad for their health. Raw food also leaves cat's teeth clean and healthy and their stools do not smell nor do they have gas. Give it a try.
