Frogs can't recognize their owners if they are kept for a long time. Frogs are amphibious cold-blooded animals and have no consciousness of their own. When a stranger approaches, it will take the initiative to attack or escape, which also leads to the process of identifying the owner, which is often difficult. Unless professionals are professionally trained, they will know their owners, but they will not know their owners like cats and dogs. It's just a reflex.

Clown frog, the full name of cat-eye pearl frog, is a kind of cat-eye frog of Bufonidae. This kind of frog called clown frog, because of its ugly and eccentric appearance, has attracted many people's love, and many people have started to keep clown frogs as pets.
