Abstract: The palatability is one of the important criteria to measure the success of pet food. Different breeds of pets or the pet at different developmental stages have different palatabilities. Animal factors cannot be ignored in the study of palatability. The special habits of dogs and cats will also affect their palatability choices in food intake，such as differences in the intake of fat，protein and carbohydrates. At present，the conditioned reflex method，the single ? bowl method and the double ? bowl method are commonly used to evaluate the palatability. While evaluating palatability，the conditioned reflex method focuses more on improving the animals’poor feeding habits. The single ? bowl method and the double ?bowl method directly compare the amount of food intake to evaluate the palatability. In recent years，new methods of using electronic devices have also emerged. These electronic devices can monitor a range of biological indicators in feeding animals to assess palatability. This paper summarizes the commonly used palatability evaluation methods for dog and cat pet food and expounds its characteristics，so as to provide a reference for the subsequent research and development of dog and cat pet food.
