Body condition scoring (BCS) provides a readily available technique that can be used by both veterinary professionals and owners to assess the body condition of cats, and diagnose overweight or underweight conditions. The objective of this study was to evaluate a five-point BCS system with half-point delineations using dual-energy x-ray absorptiometry (DXA). Four evaluators (a veterinarian, veterinary technician, trained scorer and untrained scorer) assessed 133 neutered adult cats. For all scorers, BCS score was more strongly correlated with percent body fat than with body weight. Percent body fat increased by approximately 7% within each step increase in BCS. The veterinarian had the strongest correlation coefficient between BCS and percent fat (r = 0.80). Mean body fat in cats classified as being in ideal body condition was 12 and 19%, for 3.0 and 3.5 BCS, respectively. Within BCS category, male cats were significantly heavier in body weight than females within the same assigned BCS category. However, DXA-measured percent body fat did not differ significantly between male and female cats within BCS category, as assigned by the veterinarian (P >0.13). Conversely, when assessed by others, mean percent body fat within BCS category was lower in males than females for cats classified as being overweight (BCS >4.0). The results of this study show that using a BCS system that has been validated within a range of normal weight to moderately overweight cats can help to differentiate between lean cats and cats that may not be excessively overweight, but that still carry a higher proportion of body fat.

“…Imaging techniques such as quantitative magnetic resonance (QMR) and computed tomography (CT) can be used to estimate body fat, but there has been little evaluation of their use in assessing body composition in cats (Buelund et al 2011;Zanghi et al 2013). In addition, practical use of QMR and CT is limited by the cost and technical expertise required and, for CT, the need for general anaesthesia and the exposure to radiation (Buelund et al 2011).…”

ABSTRACT:Obesity is recognised as the most common multifactorial nutritional disorder of pet cats. Studies from several countries have indicated that between 11.5% and 63% of cats are overweight or obese. Breed, age, sex, reproductive status, the pet-owner relationship, owners' perceptions of their cats' body condition, type of diet, frequency of feeding, and environment have all been identified as potential risk factors for the development of obesity in cats. Obesity has significant implications for feline health and welfare as it has mechanical and metabolic effects and can predispose cats to conditions such as diabetes mellitus type 2, hepatic lipidosis, lameness, oral cavity disease, urinary tract disease, dermatological disease, and neoplasia. An important aspect of preventing and managing obesity is the evaluation of body condition to determine ideal body weight and to formulate an appropriate weight loss plan. Several methods have been developed for this purpose. This review uses recent scientific literature to discuss various aspects of feline obesity, including its prevalence, proposed risk factors, pathogenesis, associated conditions, and methods of assessment.Keywords: overweight; obese; body condition; cat List of abbreviations BCS = body condition score, CT = computed tomography, DEXA = dual-energy X-ray absorptiometry, MMS = muscle mass scoring, QMR = quantitative magnetic resonance

“…In humans, CT, MRI and DEXA are all commonly used to measure the body fat ratio when determining the degree of obesity, and there is a strong correlation between their analytical results [13, 14]. The use of CT, MRI and DEXA in veterinary medicine has only been reported for cats [3]. …”

In small animal veterinary practices, body condition score (BCS) is generally used to diagnose obesity. However, BCS does not constitute objective data. In this study, we investigated the value of using human body fat analysis software for male dogs. We also compared changes in body fat after neutering. Changes in body fat at the time of neutering (age 1 year) and 1 year later were compared by performing CT scanning and using human body fat analysis software. We found that body fat increased in all the individuals tested. In terms of the site of fat accumulation, subcutaneous fat was more pronounced than visceral fat with a marked increase on the dorsal side of the abdomen rather than the thorax.
