First of all, the owner should often feed the tortoise by himself, bathing, cleaning, playing with it, and interacting with it, then it will gradually become familiar with the owner.

The best thing is to do everything by yourself, interact and accompany more. Feeding should follow the timing and fixed amount. You can prepare a bell and shake the bell before each feeding. If it goes to the bell, give it something to eat. Through this training, you can use the bell to attract the tortoise.
