A turtle can recognize its owner after about a month. The owner needs to feed it in person every day, feed it more of the meat, fruits and vegetables it likes to eat, and spend more time interacting with it to gradually develop a relationship with it. Although turtles are cold-blooded animals, they will recognize their owners through smell and sound, and will slowly get used to their owners' presence through conditioned reflexes.

Performances of turtle recognition:

1. Open its mouth to receive food. If the owner feeds the turtle, it will approach the turtle actively, open its mouth, and wait for the turtle to feed. This also means that the turtle recognizes the owner.

2. Identify the owner. Turtles can also distinguish between their owners and strangers. Once a stranger comes to the home, the turtle will retract its head and become a turtle with a shrunken head. When there is only one owner at home, the turtle will not be restrained and will explore everywhere with curiosity.

3. Will not run away. Speaking of the turtle's recognition of its owner, if it does not run away but approaches you when it is raised, this is also a sign of the turtle's recognition of its owner, and it may ask the owner for food.
