10 Myths About Cats Debunked by Science

Cats have been surrounded by myths and misconceptions for centuries. Some of these ideas are harmless, while others affect how people care for their feline companions. Science has helped unravel the truth behind many of these myths, proving that cats are more complex and fascinating than many believe. Let’s dive into ten common myths about cats and what research actually says about them.

Cats Always Land on Their Feet

Cats are known for their agility, but they don’t always land perfectly. While they do have a “righting reflex” that helps them twist their bodies mid-air to land on their feet, this doesn’t guarantee a safe landing. Studies show that falls from lower heights can be more dangerous since cats may not have enough time to adjust their position properly.

Veterinarians have even identified a condition called “high-rise syndrome,” where cats falling from great heights sometimes suffer fewer injuries than from shorter falls. This is because they have more time to spread their bodies and slow down their descent—like a parachute effect.

Cats Are Nocturnal

Many people believe that cats are strictly nocturnal, but in reality, they are crepuscular. This means they are most active during dawn and dusk, which aligns with the hunting patterns of their wild ancestors.

House cats often adjust their schedules to match their human companions. If a cat seems overly active at night, it’s usually because they have excess energy or a disrupted routine, not because they are naturally nocturnal creatures.

Cats Purr Only When They’re Happy

Purring is often associated with contentment, but it serves multiple purposes. Cats also purr when they are in pain, stressed, or seeking comfort. Studies suggest that purring has a self-healing effect, with vibrations helping to promote tissue regeneration and relieve discomfort.

This means a purring cat isn’t always a happy cat. If a cat is purring but also showing signs of discomfort, such as hiding or refusing food, it may be trying to soothe itself rather than expressing joy.

Cats Hate Water

While it’s true that many cats dislike water, this isn’t universal. Certain breeds, like the Turkish Van, actually enjoy swimming and playing in water. The dislike for water likely comes from their fur’s structure, which absorbs water and makes them feel heavy and uncomfortable.

Some cats also dislike water because of bad past experiences or because they weren’t introduced to it early in life. However, with patience and positive reinforcement, some cats can learn to tolerate or even enjoy water-related activities.

Cats Can See in Complete Darkness

Cats have excellent night vision, but they cannot see in total darkness. Their eyes are designed to work well in low light due to a higher number of rod cells and a special layer called the tapetum lucidum, which reflects light and enhances vision in dim conditions.

However, just like humans, they still need at least a small amount of light to see. In pitch-black environments, cats rely more on their whiskers and other senses to navigate.

Milk Is Good for Cats

The image of a cat happily drinking milk is a classic one, but milk isn’t actually good for them. Most adult cats are lactose intolerant, meaning they lack the enzyme needed to properly digest lactose in dairy products.

Drinking milk can cause stomach upset, diarrhea, and discomfort. If a cat enjoys milk, lactose-free alternatives or small amounts of specially formulated cat milk are safer options.

Pregnant Women Should Avoid Cats Completely

Many people believe that pregnant women must get rid of their cats due to the risk of toxoplasmosis, a parasite that can be transmitted through cat feces. While toxoplasmosis can be harmful during pregnancy, the risk of contracting it from a cat is low, especially with proper hygiene.

Toxoplasmosis is more commonly transmitted through undercooked meat or contaminated soil. Pregnant women can still safely live with cats as long as they avoid cleaning the litter box or take precautions like wearing gloves and washing their hands thoroughly.

A Cat’s Whiskers Are Just Like Any Other Hair

A cat’s whiskers are much more than just long hairs. They are highly sensitive sensory organs called vibrissae that help cats detect changes in their surroundings, navigate in the dark, and even gauge whether they can fit through tight spaces.

Trimming or damaging a cat’s whiskers can cause disorientation and stress. Since whiskers are deeply rooted in nerve endings, they play a crucial role in a cat’s overall awareness.

Cats Are Completely Independent and Don’t Need Attention

Cats have a reputation for being aloof and independent, but this is only partially true. While they don’t require constant attention like some dogs, they still need social interaction, mental stimulation, and affection from their owners.

Neglecting a cat’s need for companionship can lead to stress, anxiety, and behavioral issues. Many cats form deep bonds with their humans and seek affection in their own unique ways, whether through cuddles, head bumps, or simply sitting nearby.

Cats Bring Dead Animals to Their Owners as Gifts

It may seem like your cat is offering you a “gift” when they bring home a dead bird or mouse, but this behavior is actually rooted in their instincts. Cats are natural hunters, and they bring prey back to a safe place, which often happens to be your home.

Some experts believe that cats see their human companions as part of their family and may be trying to “teach” them how to hunt. Others suggest that they are simply following their natural prey instincts and stashing food for later. Either way, your cat isn’t trying to be generous—it’s just being a cat.

Cats are mysterious, intelligent, and often misunderstood creatures. While many myths about them persist, science has helped reveal the truth behind their behavior and biology. By understanding cats better, we can provide them with the care and companionship they truly need. So, the next time you hear a common cat myth, you’ll know exactly how to separate fact from fiction!
