Research Progress of Nutrition of Aging Cats and Dogs

随着宠物相关科学研究的发展，猫和犬等宠物的寿命在不断延长，极端情况下可以活到30岁以上，但伴随宠物的衰老，其营养需求并没有明确的研究进展。伴随着衰老，猫和犬的许多潜在的生理过程(例如免疫功能减退)和与年龄相关的健康状况(例如认知能力下降)都在变化，如果采取合适的营养干预手段，可能有效减缓伴随着衰老产生的健康水平的下降，提高宠物的生活质量。本文综述了当前国际上猫和犬衰老及其过程的最新研究进展，提出了老年猫和犬对营养的需求，以及与衰老相关的常见疾病的相应营养调控手段，旨在为保持宠物的健康和延长其寿命提供参考。With the development of pet-related scientific research, pets such as cats and dogs are kept for an extended period of time. In extreme cases, they can live to be over 30 years old. However, as pets age, there is no clear research progress on their nutritional needs. Many underlying physiological processes (e.g., immunocompromised) and age-related health conditions (e.g., cognitive decline) are altered in cats and dogs that, with appropriate nutritional intervention, may effectively contribute to the development of inflammation decrease in health level and improve pet’s quality of life. This article reviews the latest international research progress on cat and canine dementia and its processes, proposes the nutritional needs of elderly cats and dogs, and the corresponding nutritional control methods for common diseases related to dementia, aiming to provide reference for keeping pets healthy and extending their lifespan.
