8 Interesting Facts About Your Cat’S Brain!

Cats are adored by people on every continent. People like the personalities, brains, and perception of cats. All of these characteristics and attributes that people have valued for generations originate in the cat's brain.

Yet, little is known about the cat's brain. What size are they? Are cats truly so intelligent? How does the feline brain affect its behavior? These are a few of the topics that will be addressed in this article utilizing data obtained from scientific research and neurologists.

"8 Interesting Facts About Your Cat's Brain!" by BestForPets (bestforpets.org) includes eight astounding and intriguing facts about the brain of your cat.

The 8 Fascinating Facts About Your Cat's Brain

1. Cats’ Brains Are the Size of Your Pinky

Cats, despite their reputation as observant and clever, have extremely little brains. The brain of a cat is just two inches in diameter. This little region is where all of a cat’s faculties and instincts are stored and regulated.

Cats are extremely clever despite having relatively tiny brains. Cats’ big jaws and thick skulls occupy the majority of the space in their heads.

2. Cats Are Considered Big Brained

The Encephalization Quotient (EQ) is a scientific metric that measures the relative size of an animal’s brain in relation to its body. The quotient is greater the larger the brain. Based on brainpower, the greater the quotient, the smarter or more intelligent a species is regarded to be.

The EQ scores of animals with tiny brains and low IQs are less than one. The EQ of average animals with neutral relative brain sizes is one. Animals deemed intelligent have EQ scores greater than one.

Cats’ EQ varies from 1.2 to 1.7, indicating that cats have somewhat bigger brains and greater intellect than the ordinary animal. Comparatively, people have an average EQ between 6.5 and 7.5. The human brain is the biggest and most capable of any animal on Earth.

3. Cats Have the Same Number of Brain Cells as Bears

Cats have the same amount of brain cells in their cerebral cortex as a full-grown bear, which is an intriguing fact.

A team of neuroscientists discovered that, despite their enormous size variations, basic cats have around 250 million brain cells in their primary processing centers. Brown bears’ cerebral cortexes have 251 million cells.

Theoretically, this implies that bears and cats possess comparable decision-making speed and skill. This sort of comparison illustrates how intelligent cats are relative to animals with larger brains.

4. Cats’ Brains Are Very Lightweight

The brains of cats are rather light. In reality, the average brain weight of a cat is only 30 grams. This is equivalent to the weight of a penny or a lightbulb. In reality, 30 grams is equivalent to only 1.05 ounces.

The brains of large cats, such as lions and tigers, will weigh far more than those of domestic cats, but the weight will stay proportionate to their size; in reality, they have a lower EQ. In comparison, the average newborn human brain weighs 370 grams, or 13 ounces.

5. Cats Dream When They Sleep

Cats, like people and dogs, can dream. When a cat enters rapid eye movement (REM) sleep, it is in a dreaming state. When sleeping, cats’ brains assume a similar condition as human and canine brains.

This REM sleep stage induces relaxation and twitching of the muscles. If cat dreams are as bizarre and off-key as human dreams, we have no idea what is happening in their brains as they sleep, but we do know they are feeling something.

6. Cats Have Excellent Visual Memory

Cats possess an exceptional visual memory. This indicates that cats can recall years-old faces, people, other cats, and events. According to studies, cats are capable of retaining memories for several years. Like to people, a cat’s precise memory quality will rely on its IQ, brain health, and disposition.

Long-term memories can change a cat’s behavior over time as it adapts to prior experiences and learns to trust particular individuals or other animals. If you feel that your cat knows you every time you visit your parents’ home, even if it has been years, you are likely correct.

7. Cats Can Remember and Recognize Your Voice

In addition to having an excellent visual recall, cats also have a good hearing memory. Cats will learn your voice and remember it even if you are absent for extended periods of time. 

This form of memory is what causes a cat to run to welcome its owner. It can help ward off cats. Cats may have both good and bad associations, and if they do not like someone, the sound of their voice might cause them to hide. 

Auditory memory may also evoke traumatic memories from the past, causing cats to display apprehensive or anxious behavior based on recollections from many years ago.

8. Cats Can Get Degenerative Brain Disease As They Age

Cats are extremely intelligent and have sophisticated brain systems. Moreover, cats may have fairly long lives.

The combination of intelligence and lifespan has made cats a popular companion for centuries. Yet, this implies that cats are prone to the same kind of cognitive deterioration as humans.

Cats can acquire feline cognitive dysfunction (FCD), which is similar to Alzheimer’s disease in humans. Mental faculties of FCD-affected cats will gradually begin to deteriorate.

Cats with FCD will lose their social skills and house training. They may get easily agitated and confused and have difficulty sleeping.


As mentioned in “8 Interesting Facts About Your Cat’s Brain!” by BestForPets (bestforpets.org), brains of cats are astounding. Although though feline brains are objectively tiny, they carry a significant punch.

Cats have exceptional memory and recall. Cats have mental capabilities with considerably bigger animals such as bears and canines.

Even while asleep, cats may dream and attain a similar condition as humans. Perhaps one day we will understand what cats dream about, but for the time being we can only speculate.
