A snail is just a reptile and will never recognize its owner no matter how long it is kept. Because snails have very low IQs, they have no eyes or ears, and can only rely on their tentacles to sense things around them. They don't even know who humans are, let alone have the consciousness to recognize their owners.

Tip:

Snails have relatively low IQ and will not come into direct contact with people. When the snail's body is touched, the snail's body can't help but shrink back.
