Cats are obligate carnivores, meaning they only eat meat. There is no need for fruits or vegetables to be in cat food. Along with a food that is high in animal products, the food must also contain the right amounts of vitamins, minerals, fatty acids, and amino acids.
A common question that we are asked is, “Which is better for my cat, dry or canned?” Well, they can both be good for different reasons. Dry food is generally cheaper, stays fresh longer, and can help prevent dental tartar from forming in the first place. Canned foods carry a higher protein and water content, both of which are beneficial for cats. However, most commercially available diets offer balanced nutrition.
Dry food contains the least amount of water, usually between 6-10%. There are many different dry cat foods available and feeding the dry option allows owners to “free feed”, or leave food out all the time. But be careful with free feeding as cats tend to eat more than their metabolic needs leading to obesity. Chronic obesity, especially when feeding a high carbohydrate diet, can develop into Diabetes Mellitus similar to Type II Diabetes in humans.
Canned food on the other hand has about 75% moisture content, making it especially good for cats that need more fluid (hydration) such as cats with chronic kidney disease. Cats can be picky eaters and there are many varieties and flavors of canned food.
