Obesity is a common problem in cats. In the experimental cat family of the institute of animal nutrition besides a "normal" lean phenotype, cats with predisposition to an overweight phenotype are present. To investigate energy requirements and food intake behaviour of intact male cats of different phenotypes, six "normal" lean cats (GL) and six cats disposed to overweight (GO) were used. At the beginning of the experiment, all cats had an ideal body condition score of 5. To reach this the GO cats had to pass a weight-loss program. Energy requirements of the cats were determined using respiration chambers, whereas the amount and frequency of food intake was measured with a feeding station recording the data automatically. Energy requirement at weight constancy of the GO cats was even on fat-free mass (FFM) significantly (P = 0.02) lower (162.6 kJ/kg FFM/d) than that of the "normal" lean cats (246 kJ/kg FFM/d). The GO cats also showed a higher food intake 34.5 ± 1.5 g dry matter/kg body weight(0.67) compared to the GL cats (24.0 ± 2.1 g dry matter/kg body weight(0.67))(P = 0.001). In conclusion quantifiable differences in food intake and behaviour in cats predisposed to overweight compared to "normal" lean cats were found.
肥胖是猫类常见的问题。在动物营养研究所的实验猫群体中，除了“正常”的瘦体型表型外，还存在易超重表型的猫。为了研究不同表型的成年雄性猫的能量需求和食物摄入行为，使用了6只“正常”瘦猫（GL）和6只易超重的猫（GO）。在实验开始时，所有猫的理想身体状况评分为5分。为了达到这一评分，GO组的猫必须通过一个减肥计划。使用呼吸室测定猫的能量需求，而食物摄入量和频率则通过一个自动记录数据的喂食站进行测量。GO组猫在体重恒定状态下基于去脂体重（FFM）的能量需求（162.6 kJ/kg FFM/d）甚至显著（P = 0.02）低于“正常”瘦猫（246 kJ/kg FFM/d）。与GL组猫（24.0 ± 2.1 g干物质/千克体重（0.67））相比，GO组猫的食物摄入量也更高，为34.5 ± 1.5 g干物质/千克体重（0.67）（P = 0.001）。总之，发现易超重的猫与“正常”瘦猫相比，在食物摄入量和行为方面存在可量化的差异。
