Cat
The domestic cat possesses eighteen retractable claws distributed across four paws, each capable of extending and retracting through a sophisticated arrangement of tendons and ligaments that has remained evolutionarily unchanged for millennia. These keratin weapons serve purposes including prey capture, defensive combat, and the systematic destruction of furniture that their human cohabitants foolishly believed was for sitting upon. Documented hunting success rates place cats among the most efficient predators on Earth, with studies indicating they kill between 1.3 and 4 billion birds annually in the United States alone.
The cat's combat methodology relies upon patience, ambush tactics, and an innate understanding that victory often requires waiting seventeen hours motionless beneath a wardrobe. Their flexible spine permits rotational movements impossible for larger predators, whilst their night vision provides advantages in low-light engagements. However, cats typically limit combat to prey significantly smaller than themselves, demonstrating strategic wisdom that some might characterise as cowardice but which evolutionary biologists term optimal energy expenditure.
