Keep no more CATS than will catch mice

Insights

Utilitarian Efficiency

The proverb is a metaphor for efficiency and resource management, advising against maintaining any unproductive assets, employees, or dependents. It argues that one should only retain elements that provide a clear, functional benefit, thereby avoiding waste.

Pragmatism over Sentimentality

It serves as a warning against sentimentality in practical affairs. The 'cats' symbolize anything we might be attached to, while 'catching mice' represents its functional purpose. The proverb insists that value must be demonstrated, not just assumed or felt.

Accountability and Performance

This maxim underscores the importance of accountability. Every person or element within a system ('the cats') should be responsible for fulfilling their designated role ('catching mice'). Failure to perform justifies their removal to maintain the health of the overall system.

Principle of Household Utility

This proverb originates from a pre-industrial, agrarian worldview where households functioned as economic units. Pets were not merely companions but had practical roles; a cat's primary value was pest control. The proverb encapsulates the principle of thrift and resourcefulness, where every member of a household, human or animal, was expected to contribute to its sustenance.

Early Form of ROI

The proverb serves as a timeless principle for business and resource management, predating modern concepts like 'return on investment' (ROI) or 'lean operations'. The 'cats' are employees, assets, or expenses, and the 'mice' represent the productive output or problems solved. It's a stark reminder to eliminate waste and ensure every component serves a quantifiable purpose.

Psychology of Pragmatism

The saying reveals a psychological preference for pragmatism over sentimentality. It advises against maintaining unproductive elements out of habit, affection, or tradition, promoting a mindset where utility and performance are the primary measures of value. This reflects a cultural bias toward tangible results over emotional attachments in practical matters.
