A two-year-old hamster can still recognize a new owner. Hamsters have a very short memory. As long as hamsters get along with people for a period of time, they will remember the smell of their owners and get to know them. Hamsters are very timid, and it will take a long time for them to recognize their owners. However, as long as you keep feeding them every day and playing with them more, they will recognize their owners after they become familiar with their owner's scent.

Performance of hamster recognizing its owner:

1. Hamsters are less courageous. If a hamster frequently approaches its owner, it means that the hamster has recognized its owner and the owner will let him know. It feels safe.

2. The owner can easily touch the hamster, and some hamsters will expose their bellies for the owner to stroke, and they will relax and comb their hair in front of the owner.

3. When feeding food, the hamster will run over immediately without any hesitation.
