1. Physical Characteristics
Typically, cats weigh between 2.5 and 7 kg; however, breeds like Maine Coon can exceed 11.3 kg. Some cats have reached a weight of 23 kg due to overfeeding, which can be detrimental to their health - leading to conditions like diabetes, especially in neutered males. This can be prevented through proper diet and exercise (jumping), especially for indoor cats. On the contrary, there are also very small cats.
In indoor conditions, cats usually live 14 to 20 years, though the oldest known cat lived to be 35. House cats tend to live longer if kept indoors (reducing the risk of injuries from fights and accidents) and if they are spayed or neutered.
Cats are exceptional sprinters, reaching speeds of up to 30 miles per hour over short distances. They can jump high over a 7-ft fence or a tall wall from a standing position. Domestic cats are one of the few four-legged animals without rigid collarbones, allowing them to squeeze through openings the size of their heads.


2. Activities
Cats conserve energy by sleeping more than most other animals, especially as they age. The daily sleep time varies, usually 12–16 hours, averaging 13–14 hours. Some cats may sleep up to 20 hours a day. Since they are more active during twilight, cats are playful and often engage in antics in the evening. They primarily sleep in the early morning, afternoon, and early evening. Cat temperament varies by breed, living conditions, and gender, with females often being more affectionate than males. Short-haired cats tend to be lean and active, while long-haired cats are usually larger and more laid-back.
The body temperature of a cat is around 38 to 39 °C. A cat is considered to have a fever (high) if the body temperature is 39.5 °C or higher, or hypothermic if lower than 37.5 °C. In comparison, the normal body temperature of a human is approximately 37 °C. A normal house cat has a heart rate of about 140 to 220 beats per minute, which depends largely on the cat's activity level. When a cat is at rest, the normal heart rate is around 150 - 180 beats per minute, roughly double that of humans.


3. Cat's Ears
With 32 independently controlled muscles directing the ear's orientation, cats can raise each ear in different directions. Thanks to this high dynamic feature, cats can turn their bodies in one direction and raise their ears in another. The majority of cats have upright and high-arching ears. Unlike dogs, cat breeds with folded ears are very rare. (Scottish Fold cats are an exception.)
When angry or fearful, cats often flatten their ears backward while emitting growls or hisses. Cats also flatten their ears forward when playing or occasionally when attentive to a noise coming from behind.


4. Climbing Heights and Falling
Most cat breeds enjoy climbing to high places or sitting in elevated positions. Animal behavior researchers have provided some explanations for this behavior, with the most common being, 'height gives cats a better vantage point. From there, they can oversee their kingdom and observe human and other animal activities. In the wild, an elevated position is also used as a hiding place for hunting prey.' Therefore, height can also provide cats with a sense of safety and dominance.
However, this preference for height can be a risky trial for the common belief that a cat always 'lands on its feet.' The U.S. Animal Protection Agency has warned pet owners to be cautious of dangerous high places in their homes to avoid the 'high-rise syndrome,' which can make a cat overly confident and fall from excessive heights.
When falling, a cat can use its sharp balance sense and reflexes to twist its body to a proper position.
This ability is called the 'righting reflex.' It consistently adjusts the body balance in a way that allows them to perform this reflex when falling. Hence, falls from great heights (several stories) are less dangerous than falls from a height of only a few meters. Many cases have been recorded where cats falling from significant heights (5 to 10 stories) still survive, peacefully unharmed. Some breeds without tails lack this balancing ability because cats use their tails and rely on momentum to balance themselves in preparation for landing.


5. Cat's Legs
Similar to dogs, cats are digitigrade animals: they walk on their toes, and the bones of their feet make up the visible part of the lower leg. Cats can step very precisely, as like every other cat species, they walk directly (almost) on the trace of the front foot, minimizing noise and leaving minimal tracks. This also helps them maintain a good position of the hind foot when walking on rough surfaces.
Like all their feline relatives, except for the cheetah, cats have retractable claws. Normally, at rest, the claws are retracted in the skin and fur around the toe pads. This keeps the claws sharp as they do not come into contact with the ground and allows cats to quietly stalk prey. The front claws are usually sharper than the rear ones. Cats can extend one or more claws as needed.
They often extend their claws while hunting, for self-defense, climbing, acrobatics, or to increase friction when walking on smooth surfaces (bedspreads, thick carpets, etc.). Curved claws can get caught in thick fabric, risking injury if the cat cannot retract them.


6. Independence in Living
With the ability to climb, hide, and hunt, a cat can live independently without relying on human care as much as other animals like dogs, pigs, etc. Moreover, some cats, even when well cared for, may choose to leave and live a free life.
Becoming feral... Despite the long association of cats with humans, they still have many mysteries. There are cases where cats especially predict death or sense danger for their owners. So, to learn more, you can directly keep a cat in your home. Also, when you see a cat or images of cats, you'll get a sense of peace and relaxation...


7. Acute Senses
In various studies conducted by scientists on the feline species, the senses of cats in general, such as cat eyes, whiskers... have been particularly noteworthy.
There are many fascinating facts about cat eyes. Their eyesight is much superior to that of humans. The cat's pupil can change up to 3 times a day to adapt to changes in light. When bright light shines, the cat's pupil is just a thin line. In the morning, the pupil opens slightly larger, but when it's completely dark, the cat's pupil can expand and become completely round, allowing cats to see clearly in the dark.
Furthermore, their other senses are also quite developed. Whiskers function as a balance aid and help cats easily perceive obstacles around them. Cat fur contains some components that, when exposed to sunlight (cats love sunbathing), produce vitamin D. Therefore, cats often lick their fur to supplement vitamin D for their bodies...
Cats are very sensitive to changes in weather, climate, and the subtle effects of their surroundings. At certain times, such as during a full moon night, cats often exhibit quite strange behaviors. They become more aggressive and tend to attack everything around them. In the United States, Japan, and some other countries, to prevent cases of feral cats attacking and causing harm to humans, law enforcement often increases patrols and controls during full moon nights.


8. Hunting Instincts and Eating Behavior
Cats, being carnivorous animals, target small creatures such as mice, snakes, frogs, and fish for their survival. Their hunting weapon is the claw at the tip of each toe, measuring over 1 cm, crescent-shaped, with a small and sharp claw head. The claws of cats are a formidable weapon against their prey.
To hunt, when spotting prey, a cat typically stands at a distance of about 5 to 6 meters. It then lies flat, lowering its body close to the ground, staring intently without blinking at the target while gently approaching it. When it gets close enough and feels confident, the cat unleashes its final force by pushing strongly with its hind legs, propelling its entire body forward, and extending its sharp claws straight out to catch and seize the prey. Cats often capture their prey in a remarkable and effective manner by stretching the claws on their front paws and grabbing the neck of the prey. This is an impressive and efficient hunting technique, and the cat uses its mouth to bite the prey's head until it dies before releasing it.
Nowadays, domestic cats live with humans through many generations. Therefore, their food is varied, including rice. However, despite being carnivorous animals, wild game such as fish remains their preferred food. Humans often feed cats a mixture of rice and fish. This type of food is favored by cats because it has the fish's distinctive odor. Domestic cats also eat wild game, but in reality, they prefer fish much more. Cats often come to the edge of a pond to drink water and catch fish. Fish and mice are always the most popular food for cats.


9. Remarkable Navigation Memory
Cats can memorize and navigate unseen paths, returning to their 'old home' effortlessly!
Cats perceive surfaces through an energy network created by the Earth's magnetic fields. This field resembles a neatly arranged carpet with intricate patterns. Some psychic individuals claim it is an organized network similar to a beehive.
Others believe the Earth's surface is marked like a checkerboard, with parallel lines occasionally intersecting neighboring areas. Zoologists assert that frogs, lizards, dolphins, and certainly cats have excellent self-orientation abilities with the support of the mentioned network.
In the past, people were skeptical about news reports stating that cats could return home after being taken hundreds of kilometers away! For example, a cat named Sugar in California escaped from its owner's car during a trip and went missing. However, a year later, Sugar found its way back to the 'old home' over a distance of... 2,400 km!
In another case, a cat named Suti moved to a new house with its owner, but perhaps not enjoying the new environment, Suti decided to return to its old home. Miraculously, after a 5-month journey of over 150 km on foot, Suti set foot in its 'hometown'!
Today, scientists have made significant advances in researching and uncovering the mysteries of the feline world. Cats have incredible visual memory, but they use this ability to find their way home over short distances in their living areas.
Once visual memory proves futile, domestic cats are guided by the Earth's magnetic field on the ground. Interestingly, cats do not need to see the path to memorize it when leaving home. A cat can easily remember the route even when confined in a bag while traveling far from home.


10. Reproductive Behavior
Cats reach sexual maturity between 5 to 9 months, with some cases exhibiting signs as early as 4 months. The ideal time for breeding is around 1 year old when they have fully developed in health and physiology.
During mating, female cats bite and scratch male cats, vocalizing loudly with visible signs of genital bleeding. Male cats, in heat, mark territory by spraying urine. Throughout this period, the reproductive system of cats is always ready and highly stimulated.
The estrus cycle typically lasts from 7 to 10 days, and if not pregnant, female cats will return to heat.
Pregnancy in female cats lasts about 9 weeks, and they can give birth to 3 to 4 litters per year, with each litter consisting of around 3 to 4 adorable kittens.
When kittens are born, their eyes are tightly closed, and their ears are adorable little folds. Upon opening their eyes for the first time, they have a blue hue, which changes several times over the first few months.


11. Cats Inherently Maintain Self-Grooming Habits
Cats are renowned for their cleanliness. They instinctively protect their bodies from damp places and show little enthusiasm for bathing. They often dislike their fur getting wet or any foreign objects sticking to it as they wander through a thicket or near a pond. Even a human's touch can disturb them, potentially altering the scent of their fur. Hence, they are acclaimed as one of the cleanest creatures.
To maintain hygiene, a cat extends its tongue, moistens its paws with saliva, and applies it to its face and entire body. This action signifies its intention to cleanse away dirt, even the touch of a human hand. Cats groom themselves multiple times a day, especially upon waking or returning from outside. This behavior has become a habitual practice, observable even when their bodies are spotless. Cats are animals that consistently prioritize body cleanliness.


12. The Rarest Cat Breeds in the World
Sand Cat: Also known as the sand dune cat, this species inhabits desert regions of Africa and Asia. Sand cats thrive in arid, sometimes even more inhospitable conditions than African wildcats can endure. Small in size, with short legs, long tails, and remarkably large and bushy ears, sand cats have light golden fur resembling the color of sand, adorned with faint, hard-to-spot golden stripes. Their chin and abdomen are white. Sand cats possess fur between the pads of their feet, creating an insulating layer that protects them from burning on the hot desert ground and easily navigating rocky terrain. Adapting to a habitat in dry areas, sand cats are prone to injuries and respiratory infections when kept in captivity. The sand cat faces the risk of extinction due to illegal hunting and habitat loss.
Black-Footed Cat: This small carnivorous mammal, sparsely studied in Africa, was listed as vulnerable by the International Union for Conservation of Nature (IUCN) in 2002, with only about 8,300 remaining. The black-footed cat is the smallest cat species globally, with black coloration beneath its feet and lower legs. The color of their fur varies between individuals, often featuring interspersed brown or black spots forming rings on their legs, neck, and tail. However, their neck skin is pink and unspotted, with large eyes. Black-footed cats typically inhabit South Africa, favoring habitats like dry savannas, open grasslands, and large bushy deserts.
Pallas's Cat: Also known as the manul, Pallas's cat is a small wild cat native to Central Asia. Similar in size to domestic cats, their fur is dark brown with dark stripes along the body and front legs, distinct black rings on the tail, and dark spots on the forehead. Their winter coat is grayer and less patterned than their summer fur. They have short, proportionally wide legs, low-set and broad ears, and unusually short claws. Pallas's cats are distributed across grasslands and steppes in Central Asian mountainous regions. They face negative impacts from habitat degradation, prey reduction, and hunting, with a population of just over 9,000, leading to their near-threatened status according to the IUCN in 2002.
Leopard Cat: The leopard cat is a small cat native to South and East Asia. At first glance, they might resemble small leopards, but their kinship is more distant. Similar in size to domestic cats, they possess a coat with beautiful leopard-like patterns. Due to their visually appealing fur, highly sought after in the commercial market, leopard cats face significant threats. With just over 1,000 individuals remaining, legal measures have been implemented over the past decade to prevent any activities contributing to the decline of leopard cat populations.
Jaguarundi: Also known as the American bush cat, the Chausie, or the Chaus, the jaguarundi is a small wild cat. It is closely related to large felines like the cougar and the lion but significantly smaller. With a short, slender body, long tail, and gray-black coat, jaguarundis have adapted to live primarily in the trees. This species has an omnivorous diet, consuming anything they catch, mostly arthropods and leaves. The jaguarundi is under threat due to habitat loss and hunting, and its population is estimated to be around 6,000 individuals. Their unique habit of living in trees makes them exceptional among cats.
