The term "miner's cat" refers to a small, agile feline that was used to detect dangerous gases in coal mines. Some synonyms for this term include "mine cat," "pit cat," "coal cat," and "colliery cat." These cats were often treasured by miners for their ability to sense the presence of dangerous gases, such as carbon monoxide, before they became potent enough to harm humans. Despite being small in size, these cats played a critical role in ensuring the safety of miners working in coal mines, and are commemorated in many mining communities worldwide. While no longer used for this purpose today, these cats remain an important part of mining history.
