Is the debate over whether cats or dogs are smarter ever-ending? While it’s true that dogs typically have larger brains—especially in bigger breeds—they also boast a higher number of neurons. For instance, a golden retriever was found to have 623 million neurons in its cerebral cortex, compared to 429 million for smaller dog breeds and 250 million for cats. Overall, dogs have more neurons, which often contributes to their cognitive abilities.
However, sheer neuron count isn’t the only metric of intelligence; it’s about how they use them. There’s been more research conducted on dogs than on cats, allowing us to better understand canine intelligence. Moreover, studying cats poses challenges, as they tend to dislike unfamiliar environments, such as laboratories (who hasn’t seen a cat hide when the carrier comes out?).
Despite this, scientists have assessed the intelligence of our beloved pets across three critical dimensions.
Social Intelligence
The ability of animals to understand others’ mental states, or social cognition, can be assessed using the unsolvable task paradigm. This simple test involves a dog learning to retrieve food from a container, only to have the container fixed shut, rendering the food inaccessible. Researchers then observe if the dog seeks help from a nearby human. This behavior—looking from the person to the container and back—is a form of referential signaling or ‘showing’ behavior, akin to pointing.
Interestingly, when presented with this unsolvable puzzle, dogs often look to humans for assistance. Studies reveal that when both their owner and a stranger are present, dogs may focus solely on their owner or engage with both. This behavior suggests that dogs are keen observers and notice who typically provides solutions.
So what about cats? Although fewer studies exist on feline intelligence, one experiment found that both dogs and cats could locate a hidden piece of food when a person directed them to it. However, most cats did not ask for help and simply attempted to obtain the food on their own.
Cats do exhibit some visual communication skills. Another study indicated that cats show slightly more gaze alternation between a human and a food container when it’s clear the container is unsolvable, compared to solvable puzzles.
This research showed that cats interact more with the container and a human when the person is inattentive, suggesting they can discern between attentive and inattentive individuals, a skill they share with dogs.

Counting
If you regularly give your pet three treats but one day provide only one, will they notice? Do they possess counting skills? The answer is yes, both cats and dogs can discern quantities!
To evaluate ‘quantity discrimination,’ scientists present pets with various food options (e.g., one piece vs. eight pieces) and observe their choices. Studies indicate that adult cats and dogs can successfully differentiate quantities, including kittens and two-month-old puppies, albeit with less accuracy.
Both species primarily rely on their sight to count food quantities effectively; other senses, such as smell, are less reliable. For instance, dogs often fail to choose the larger quantity if only odor is available.
Self-Awareness
The mirror test evaluates self-awareness: a mark is placed on an animal, and if they attempt to remove it after seeing their reflection, it indicates self-recognition. While animals like bonobos and chimpanzees pass, both cats and dogs do not succeed in this visual test.
What about a scent-based version? Biologist Dr. Marc Bekoff conducted a ‘yellow snow’ test with his dog, Jethro. In this study, Bekoff observed that Jethro was more curious about snow marked by another dog’s urine than his own, even if Jethro didn’t witness the movement.
Prof. Alexandra Horowitz formalized this ‘smell’ mirror test by incorporating scent from the spleen of a deceased dog into a healthy dog’s urine. Her findings indicated that dogs spent more time sniffing their urine when it contained the added odor, demonstrating strong self-recognition abilities.
As for cats, research indicates they can identify their own feces, differentiating it from both familiar and unfamiliar cats. This resembles Bekoff’s yellow snow test, but would need an added scent to qualify as a true ‘smell’ mirror test, which hasn’t yet been conducted with cats in lab settings.
Final Verdict
Intelligence encompasses numerous factors across various scenarios, and we should be cautious about evaluating it solely from a human perspective. One way to approach this is to consider whether dogs and cats could survive independently.
Interestingly, most cats can thrive and source their own food, while some dogs may struggle. Individual differences play a role too; the pet beside you may be smarter or less so than average. Factors like genetics, socialization, early experiences, and daily life impact their intelligence levels.
Training can enhance intelligence; even cats can learn through positive reinforcement. While we can’t be certain, it’s possible that the additional socialization and training dogs typically receive provide them an edge when faced with cooperative tasks.
Breed is another factor worth considering. The Genius Dog Project studies which dog breeds can learn the names of at least ten different toys.
While many ‘dog geniuses’ are border collies, other breeds and mixed-breeds exhibit similar abilities. Notably, there are no known cats with this capability, although it remains a rare skill even among dogs.
In conclusion, both dogs and cats display remarkable intelligence, albeit in diverse forms. The most important message is to cherish the unique attributes of your pet and appreciate them for who they are.
