The four-year-old blue cat for adoption will recognize its owner. Adult blue cats will also recognize their new owners after being patiently raised, but it will take longer. The owner should accompany it more, feed it regularly, interact with it frequently, and give appropriate praise and rewards during the interaction, which can effectively promote the relationship between the owner and the cat. When a blue cat feels the owner's care, it will trust the owner more and more, rely more and more on the owner, and will naturally recognize the owner.

Shows of a blue cat recognizing its owner:
1. After a blue cat recognizes its owner, it is very dependent on its owner and sticks to its owner all the time, even sleeping next to the owner.
2. When the owner calls its name, it will react immediately, look at the owner with its eyes, or run to the owner.
3. Does not resist the owner’s touch, likes to have physical contact with the owner, and is willing to expose his belly for the owner to touch.
