In total, according to Mars Petcare, there are 522 million dogs and 399 million cats in the world.
In 2016, the research company GfK conducted a large survey of residents of 22 countries dedicated to pets.
It turned out that almost everywhere dogs are more popular than cats.
Globally, 33% of families have dogs and only 23% have cats.
Cats were unable to appreciate the behavior of a person who refused to help their owners.
The pets did not recognize these people as a threat and agreed to accept a treat from them.
On average, a dog's brain is larger than a cat's.
Scientists estimate that dogs understand between 165 and 250 words and phrases.
Moreover, cats demonstrate greater problem-solving skills and find answers faster than dogs, and also show greater ability to learn through observation.
Pets strengthen the heart. It's simple: children with dogs are more active than children without dogs, which means their hearts are healthier.
Both dogs and cats, at the same time, help reduce stress levels and stabilize blood pressure.
