Cats are obligate carnivores. Ok, great. What does that really mean? It means that a cat has a biological necessity to eat meat for its survival. Their bodies have adapted to eating animal flesh in the form of small prey. They do not need carbohydrates to thrive. The small prey also provides much of the fluid that the cat needs. Kibble that most people feed their cats lacks the necessary moisture for the cat's dietary requirements.
We strongly believe that a raw diet is the best diet we can provide for our cats. At Abscatz, we make our own raw on a monthly basis. We start our kittens on a raw diet to provide them with the best foundation for a healthy life. We have seen the results that a raw diet provides - more muscle tone, healthier coats, increased energy, and better overall health, including less digestive and/or urinary tract issues.
We do recognize that some families cannot or will not serve their cats a raw diet. There is nothing wrong with giving your cat commercial wet or dry food. We offer it to our cats as well. We offer our cats, mostly, grain-free wet and/or dry food. This goes back to the original topic - as obligate carnivores, cats do not need to eat grains to survive. So no grains. We also avoid meat by-products. Two other items that you don't want to see in your cat's food are guar gum and carrageenan. Both are food stabilizers, causing the food to stay intact and appear fresh. Guar gum is known to cause gastric distress and inflammation, while carrageenan is a potential cancer causing agent.
Currently we give our cats Orijen, Merrick, Weruva, Hounds & Gatos, Nulo and American Journey wet food. For dry food, we give them Orijen and American Journey. Merrick and Instinct are also good products and have both wet and dry food selections that your cats will like that are grain free.
