The article evaluates the performance of the algorithm system and the ability of operators in determining body composition in dogs and cats. The study involved dogs and cats with obesity, weight loss, jaundice, abdominal pain, chronic renal insufficiency, and diabetes mellitus cases, referred to the Small Animal Hospital at the University of Liverpool. Subjects were assessed by two investigators with a newly-developed 7-point algorithm system (Size, Health, And Physical Evaluation) and another with 9-point silhouette system. Findings show that the algorithm system produced significant outcome similar with the previous scoring system. Thus, the new system earned approval from operator experts, although further studies is needed to validate its performance.

The article investigates the influence of diet energy density alterations on energy intake in cats by researchers from Melton Mowbray, England. The researchers attempt to examine the effect of dietary dilution on intake in a large population of cats over an extended period of time. Anecdotally, cats were believed to have the ability to regulate intake to maintain adequate micronutrient and energy intake. As natural carnivores, the energy composition of a cat's prey is relatively constant in both density and nutritional quality. Therefore, cats have no need to evolve the rapid adaptation mechanisms of other species, such as rats, that eat a variety of foodstuffs.
