Weight loss considerations in the older cat

Abstract

The companion animal population is continuing to live longer, with approximately 40% of pet dogs and cats aged 7 years or older. Continued improvements in veterinary care and disease prevention strategies, veterinary nutrition, breeding and husbandry are just a few of the factors contributing to pet longevity, resulting in a significant population of senior small companion animals. This article considers the most common causes of weight loss in the older cat through review of the definitions and pathophysiology of muscle loss, and examining the most common concurrent metabolic and endocrine diseases associated with weight loss in the older feline patient.
