Can the hamster understand his master?

This is obviously incomprehensible. I have raised many hamsters, and none of them can understand human speech.

From the hamster's vision, things more than one meter away are already blurred. Hamsters rely more on hearing and smell to survive, so they can't even perceive people as a whole.

However, it may be familiar with the owner's smell. For it, human voice is just a vague signal, so it is impossible for it to understand people's words.
