Measurements of nitrogen, carbon and energy balances were done on eight female adult cats aged approximately 1.5 years with the help of respiration chambers. The cats were fed with a marked dry food for kittens (Biomill kitten). Faeces and urine samples were collected with the help of a special cat toilet that allows the single collection of both materials. The calculated energy requirement of these eight female cats was 239.6 kJ ME/kg BW/day (R(2) = 0.98). Including the data, on 12 young male adult cats, of Läuger, (2001), an energy requirement of 238 kJ ME/kg BW/day (R(2) = 0.95) could be calculated. From these data, it can be followed that the energy requirements of young, active cats are higher than that of the older cats. The method of indirect calorimetry does not necessarily lead to lower energy requirements.
借助呼吸室对八只年龄约1.5岁的成年雌性猫进行了氮、碳和能量平衡测量。这些猫喂食了一种专门为小猫设计的标记干粮（Biomill小猫粮）。粪便和尿液样本通过一种特殊的猫厕所收集，该厕所允许分别收集这两种物质。这八只雌性猫的计算能量需求为239.6千焦代谢能/千克体重/天（R² = 0.98）。纳入Läuger（2001年）关于12只年轻成年雄性猫的数据后，可计算出能量需求为238千焦代谢能/千克体重/天（R² = 0.95）。从这些数据可以看出，年轻、活跃的猫的能量需求高于年长的猫。间接测热法不一定会导致较低的能量需求。
