Cats and brown bears have similar smarts, even though bears' brains are about 10 times larger, according to the study.
Studies show that dogs have a significantly higher number of neurons in the brain than cats, primarily due to their larger brain size. Although the dog's brain is larger than the cat's, there's no clear winner here either.
Within the encephalization quotient proposed by Jerison in 1973, values above one are classified big-brained, while values lower than one are small-brained. The domestic cat is attributed a value of between 1–1.71; relative to human value, that is 7.44–7.8.
In fact, cats are among the most intelligent creatures on the planet. Although studies on feline intelligence are ongoing, scientists believe that cats are uniquely smart when compared to dogs and other animals. And of course, if you're a cat owner, you've likely seen evidence of your cat's intelligence firsthand.

1: Chimpanzee
Chimpanzees can learn sign language to communicate with humans. Topping our list of smartest animals is another great ape, the chimpanzee. The impressive intellectual abilities of this animal have long fascinated humans.
Dolphins are often cited as the second smartest animals on Earth due to their relatively high brain-to-body size ratio, the capacity to show emotion, and impressive mimicry of the dumb apes who research them.
Dogs, it turns out, have about twice the number of neurons in their cerebral cortexes than what cats have, which suggests they could be about twice as intelligent.
Do cats remember people? Cats possess excellent long-term memories. They can recall their animal companions and the people who feed them as well as those who irritate them. Memory is what allows a cat to leap into the arms of a family member returning after a semester away at college.
While many people think that cats are standoffish and aloof, the truth is that they are loyal, loving companions (just like dogs). The key is that cats show their love in very different ways than dogs. Usually, those expressions of love are fairly subtle, so we miss them.
For years, dolphins have been heralded as the smartest animals on Earth, second only to humans—though some would even contest that ranking. Aside from humans, dolphins have the greatest brain-to-body ratio among animal species, including primates.
Cats and dogs are colour blind
To see in full colour as we know it, humans use three cones – red, blue and green. However cats and dogs only have blue and green cones. This means they have a much more muted perception of colour, which is akin to colour blindness in humans.
C ats are just as loyal as dogs and children, according to new research. Although feline pets are seen as distant and aloof, researchers claim this is an unfair myth. Study leader Dr Kristyn Vitale of Oregon State University, said: “Cats that are insecure can be likely to run and hide or seem to act aloof.
A Cat's Brain is Extremely Complex.
The study estimated that cats have roughly 250 million neurons in their cerebral cortexes — making them pretty darn smart. Comparatively, humans have an estimated 16 billion neurons, while dogs have 400-600 million neurons.
According to a study1 published in 2019 in the journal Scientific Reports, cats do, in fact, recognize their own names. The lead author of the study is a behavioral scientist named Atsuko Saito from Sophia University in Tokyo, whose prior research2 demonstrated that cats can recognize their owners' voices.
Koalas. Koalas are not only extremely cute, they're smart, too! The marsupials know how to listen to their bodies and can dive into a deep sleep for an average of 22 hours a day. Koalas snack on eucalyptus leaves, which aren't high in nutrients—the abundant rest makes this diet possible.
The human brain is about three times as big as the brain of our closest living relative, the chimpanzee. Moreover, a part of the brain called the cerebral cortex – which plays a key role in memory, attention, awareness and thought – contains twice as many cells in humans as the same region in chimpanzees.
The encephalization quotient (EQ) (the size of the brain relative to body size) of elephants ranges from 1.13 to 2.36. The average EQ is 2.14 for Asian elephants, and 1.67 for African, with the overall average being 1.88.
Horses and Dogs are both intelligent animals, but they have different cognitive strengths. Horses excel in areas like navigational intelligence while dogs do better with social intelligence. Neither animal is smarter than the other, that's just what makes them unique!
They have broad social abilities too, like distinguishing individuals out of a group; communicating with each other through touch, smell, sound, and sight; and learning to pick up on the verbal and nonverbal cues of humans. Researchers have even found that pigs are able to use tools and play video games!
