REM sleep time in a 12 hr period was found to predict accurately food intake in the subsequent 12 hr period in undisturbed cats fed ad lib. In all but one of the cats, the correlation between REM sleep and subsequent food intake was negative. REM sleep was a better predictor of food intake than either waking, slow wave sleep or previous food intake. Cats were then fed only during the 12 hr day period. It was found that REM sleep at night, during which no food was available, no longer predicted food intake.
在自由采食的未受干扰的猫中，发现12小时时间段内的快速眼动睡眠（REM睡眠）时间能够准确预测随后12小时时间段内的食物摄入量。除了一只猫之外，在所有其他猫中，快速眼动睡眠与随后的食物摄入量之间的相关性均为负相关。与清醒、慢波睡眠或先前的食物摄入量相比，快速眼动睡眠是食物摄入量更好的预测指标。然后只在白天的12小时时间段内给猫喂食。结果发现，在夜间没有食物供应时的快速眼动睡眠不再能预测食物摄入量。
