家猫每秒钟吮吸四次奶，每次大约能喝到0.1毫升的牛奶，而体型大的猫会自然放慢吮吸速度，以保持重力和惯性之间的平衡。
Mathematician Jeffrey Aristoff said: "Our research —the experimental measurements and theoretical predictions —suggests that the cat chooses the speed in order to maximize the amount of liquid ingested per lap. This suggests that cats are smarter than many people think, at least when it comes to hydrodynamics."
数学家Jeffrey Aristoff表示："我们根据试验测算和理论预测进行的研究表明，猫会选择吮吸牛奶的速度，保证每次都能喝到最多的奶。这充分说明它们比人们想象中更聪明，至少在流体力学方面"。
