While the domestic cat is a common pet, its ancestor, the European wildcat, remains a reclusive predator that avoids human contact and maintains a strictly carnivorous diet.
From Middle English wyld cat, wylde cat (in the plural as wild cattes, wylde catis, wyle cattes), equivalent to wild + cat. Cognate with Middle Low German wiltkatte, German Wildkatze, Swedish vildkatt. Its adjectival senses were originally American and derived from the "wildcat banks" of Michigan, following its elevation to statehood in 1837. Two laws—one easing the requirements for establishing a new bank and another occasioned by the Panic of 1837 that removed the need for payment in specie—led to the creation and collapse of around 50 banks within two years. The term is apocryphally derived from a wildcat supposedly featured on the currency printed by one of these banks, but more probably derived from the remote locations "where the wildcats roamed" chosen by these banks to avoid oversight and minimize redemption of notes.
Often used as a modifier before another noun, such as in 'wildcat strike' or 'wildcat well'.
