The topic of this B. Sc. Thesis is the differences between adult dog and cat nutrition. The main goal of this B. Sc. Thesis is to figure out differences between nutrient needs for adult dogs and nutrient needs for adult cats, review chemically and the raw material composition of some compound in feed mixtures for adult dogs and compare it with some compound in feed mixtures for adult cats. To do this, we reviewed the literature for the theoretical foundations of adult dog and cat nutrition and some declarations of compound in feed mixtures for adult dogs and cats and compared them with each other. We found that the digestive tract of dogs is different from the digestive tract of cats in length, number of teeth in oral cavity, gastric function, intestinal absorption capacity and so on. As a result, they have different nutrient needs. After reviewing the chemical and raw material composition of compound in feed mixtures we found out, that feed mixtures of adult dogs and cats were quite similar to each other. We also found out some differences, such as the presence of amino acid taurine in compound of feed mixture for adult cats. There is also an obvious difference in the content of carbohydrates which feed mixtures for adult dogs contains more than feed mixtures for adult cats and in content of proteins which feed mixtures for adult cats contains more than feed mixtures for adult dogs. We also found that the cheaper feed mixtures contains more additional ingredients (e.g., blueberries, chicory, algae, flaxseed, egg, etc.) than more expensive feed mixtures.
