1. Cats' friendliness develops in the first two months of their life.
Although many people consider cats to be loners, they love to interact with people to get to know them better or to make friends with them. Cats typically learn to socialize with both other animals and humans during the first two to seven weeks of life. Individuals who interact more with people during this period will be more friendly towards them for the rest of their lives, a 2015 study shows.
2. Cats can consider people as relatives
Researcher John Bradshaw, who wrote a book on feline psychology, believes that cats see us as clumsy, huge relatives who walk on two legs and often behave unpredictably. He put forward this hypothesis based on his observations, which lasted more than 20 years. According to him, the behavior of cats with people is indistinguishable from the way they interact with other individuals of their species. For example, cats will often approach their owners with their tails raised and rub their owners' legs or lick their faces. They will similarly greet other cats that they are friendly towards.
3. Cats probably dream
Veterinarians suggest that cats can most likely not only dream, but also remember them. During certain phases of sleep, they can make uncontrolled movements of their muzzle, whiskers, paws and even their stomach. It is possible that they may have nightmares, although science has not yet found definitive proof of this.
4. Cats can remember a lot.
Researchers from Japan experimentally discovered in 2016 that cats have memory. The experiment consisted of several stages. In the first, they placed four bowls in front of 58 pets: two contained food, one contained an inedible item, and one was empty. Scientists arranged it in such a way that cats could only eat from one. After 15 minutes, the scientists gave the cats the same four bowls, but this time they were empty.
The results showed that the cats spent more time exploring the one bowl where food was left untouched in the first round, because they “remembered” that they had not gotten to it in the first place. The researchers hypothesized that they might be able to create simple “memories” in this way. According to the study's lead author, Saho Takagi, this explains why pets may be afraid of going to the vet: their fear is related to past experiences. In this regard, it is extremely important to make each visit to the doctor calm and pleasant for the cat, without hoping that he will forget about everything.
5. Cats understand when you call them by name.
Several studies in Japan and Hungary have shown that cats can interpret human gestures to find hidden food, recognize their owner's voice, and beg food from a person who looks at them and addresses them by name. This led scientists to believe that cats may understand when they are called by name that the name refers to them.

Saito and his colleagues tested this hypothesis for five years: from 2012 to 2017, they observed domestic cats and those that lived in a cat cafe. In these studies, scientists asked owners and strangers to call the cat by name, and then videotaped reactions indicating recognition, such as tail flapping, ear and head movements.

In a series of four experiments, a team of scientists found that cats responded to their own names even after hearing four similar-sounding words. Moreover, domestic cats showed interest when they were called not only by their owners, but also by strangers. Scientists have concluded that this is due to the fact that the response can bring the cat both a reward in the form of food, affection or play, and what she will perceive as punishment, for example, a trip to the veterinarian or a bath. Due to the formation of such a reinforcement mechanism (both positive and negative), the name is fixed in the cat’s brain.
