If you want the tortoise to recognize its owner, you must not frighten it casually. You can take the initiative to feed it and train it. The training method is simple. When interacting with the tortoise at ordinary times, it can be made to do some actions, so that it can be trained to form a reflex, and it can be rewarded when it makes actions. In addition, it should be noted that it is best not to touch the turtle's palm with your hands, because the high temperature of the palm is not good for its health.
The little turtle is not a person, even if he knows it, he can't see it. If the tortoise is older, raised for a long time or raised by yourself, it may have a sense of familiarity with you. Some clever turtles or those that have been kept for a long time will look very human. Now take good care of them. If you take good care of them, you should play with them more, don't abuse them, and let them know you when they grow up. For example, when feeding, put the food in front of them and let them bite your fingers more.
