What is the name of the cat door? - in detail
The cat door is commonly referred to as a "cat flap" or "pet door." It is a small opening designed specifically for cats or other small pets to enter and exit a house or room without requiring human assistance. Typically installed in doors, walls, or windows, the cat flap allows pets to move freely between indoor and outdoor spaces. Modern cat flaps often come with advanced features such as microchip recognition, which ensures only the designated pet can access the flap, or magnetic locks for added security. The design and functionality of a cat flap can vary widely, ranging from basic manual models to automated, energy-efficient versions. Historically, cat flaps have been used for centuries, with some of the earliest examples attributed to Sir Isaac Newton, who reportedly installed one for his cat. The name "cat flap" has become the standard term in English-speaking regions, though it may be referred to differently in other languages or cultures. Its purpose remains consistent: to provide convenience for pet owners and autonomy for their cats.
