Why do cats like boxes so much? After all, how often do you see a cardboard box out in the wild for feral cats to find and explore? Behavioral biologists and veterinarians believe one reason cats like boxes is because they provide a sense of security. Boxes allow cats to hide from predators as they adjust to their surroundings.
According to a 2006 study by the National Research Council, the thermoneutral zone for a domestic cat is 86 to 97 degrees Fahrenheit. So enclosed spaces like a box means cats are “comfortable” and don’t have to generate extra heat to keep warm or expend metabolic energy on cooling.
