A cat will recognize its owner once it has had one. The length of time it takes for a cat to recognize a new owner is uncertain and depends on the relationship between the cat and the previous owner, the age and personality of the cat, and the way the new owner treats the cat. If the new owner raises the cat properly, when the cat starts to actively ask the new owner for food and rubs the new owner's legs with its body, it means that the cat has recognized the new owner.

Things to note when letting a cat recognize its new owner:

1. When a cat first arrives at the new owner’s home, the cat will be very nervous and scared in a strange environment. Do not Be anxious to touch the cat, otherwise the cat may attack the new owner or have a stress reaction. Give the cat enough time to become familiar with and adapt to the new environment.

2. When adopting a cat, you can bring some of the items they originally used. Having familiar items in a strange environment can relieve their nervousness and fear.

3. Reduce contact with the original owner. If the cat has frequent contact with the original owner after changing to a new owner, it will make it more difficult for the cat to recognize the new owner.

4. In addition to feeding the cat regularly and quantitatively every day, the new owner should also spend more time and patience with the cat, interact and play with the cat, so that the cat will gradually recognize the new owner.
