Why Do Cats Do That? Baffling Cat Questions Explained!

This paragraph discusses the domestication of cats, challenging the notion that humans domesticated cats. It introduces the hypothesis that cats may have domesticated themselves and explores the possibility of multiple domestication events in different regions. The oldest known domestic cat skeleton was found in Cyprus, dating back 9,500 years, suggesting that cats may have been attracted to human settlements due to the abundance of rodents. The paragraph also touches on genetic evidence supporting the domestication hypothesis and the idea that cats may have evolved to be more sociable and less aggressive in response to human selection over millennia.

This section delves into the nocturnal vision capabilities of cats, explaining the structure and function of the eye that allows them to see better in low light conditions. It describes the tapetum lucidum, a reflective layer behind the retina that enhances night vision. The paragraph also addresses the phenomenon of cats' eyes glowing in the dark, which is due to the reflection of light from the tapetum lucidum. It explains that the color of the glow varies depending on the animal's eye structure and the presence of specific molecules. Additionally, the paragraph humorously contrasts the cat's majestic nighttime hunting prowess with its inability to see food placed directly in front of it due to its limited close-focus vision.

This paragraph examines the unique vocalizations of cats, specifically the ability to purr versus roar. It explains the anatomical differences between cats that can purr and those that can roar, focusing on the structure of the hyoid bone and the presence of thick vocal fold pads. The paragraph clarifies that while the hyoid bone's flexibility is crucial for roaring, the presence of these pads is also necessary for a lower-pitched sound. It also addresses the exception of the snow leopard, which cannot roar despite having a flexible hyoid bone. The explanation includes the physiological mechanisms behind purring and the genetic predisposition that determines a cat's response to catnip.

This section explores the misinterpretation of cats' facial expressions, particularly the 'flaming' or 'smearing' face, which is often mistaken for a sign of disgust. It explains that this facial expression is actually a specialized way for cats and other animals to enhance their sense of smell, using the vomeronasal organ located in the roof of the mouth. The paragraph clarifies that this behavior is not a sign of displeasure but rather an instinctive response to sniff the environment. It also touches on the evolutionary loss of this secondary smelling system in humans.

This paragraph investigates the reasons behind cats' strong reactions to catnip, a plant from the mint family. It identifies nepeta lactone as the compound responsible for the attraction, which mimics a cat's natural pheromones. The paragraph explains how this molecule interacts with the cat's olfactory receptors, stimulating areas of the brain associated with scent, emotions, and sexual response. It also discusses the genetic predisposition to catnip sensitivity and the temporary nature of a cat's reaction to it. Additionally, it mentions other plants that produce similar effects on cats due to the presence of pheromone-like molecules.

This section explores the endearing behavior of cats 'making biscuits,' which involves kneading with their paws on a soft surface. It presents theories explaining this behavior, including the idea that it's a way for cats to mark territory using their scent glands or a retained juvenile behavior from kittenhood, where it was necessary for milk production. The paragraph suggests that domestic cats may have evolved to exhibit more social behaviors, including this one, as a result of living with humans. It also touches on the psychological comfort that cats derive from this action and how it signifies trust and safety in the presence of their human companions.

This paragraph discusses the peculiar habit of cats to favor small spaces like boxes. It explains that this behavior provides cats with a sense of security and a place to observe their surroundings without the threat of attack, aligning with their natural instincts as ambush predators. The paragraph also highlights a study that demonstrates how providing boxes can significantly reduce stress levels in cats, especially in new environments. Additionally, it mentions that boxes help cats maintain their preferred body temperature, which is higher than the ambient temperature preferred by humans.
