There are several explanations.
The first and most popular reason is that a pet that was weaned too early from its mother cat begins to perceive a person as a parent, which means that it does not want to lose sight of him.
Besides, this way the animal feels safe.
Also, the cat may need something, and in this way it attracts attention.
For example, an animal may want to eat or play. If you solve the pet's problem, it will soon start doing its own thing.
It is worth remembering that cats are social and curious creatures. If a person in the house does something, for example, moves things from one room to another, then the pet may want to know more about what is happening.
But there may also be cause for concern if the cat follows its owner around the house. The animal may feel anxious, in pain.
Therefore, you need to pay more attention to your cat’s behavior and, if necessary, contact a veterinarian.
