Cats will change owners after recognizing their owners. If the new owner patiently accompanies the cat and interacts and plays with the cat more, the cat will recognize the new owner after a period of time. However, the length of time a cat takes to recognize a new owner has a lot to do with the relationship between the cat and the previous owner, the cat's age and personality, and the new owner's feeding methods.

Things to note when cats change owners:

1. When the cat first arrives at its new home, the new owner should not be in a hurry to touch the cat. Cats will be very nervous when they arrive in a new environment, so they need to be given enough time to adapt to the new environment. You can also bring some items that the cat used before. Having items that the cat is familiar with in the new environment will relieve the cat's nervousness.

2. The new owner should feed the cat regularly and quantitatively every day, so that the cat knows that it is the new owner who gives it food, so that it can trust the new owner.

3. The new owner should spend as much time as possible with the cat every day. After the cat becomes familiar with the new owner, he can interact with the cat and play with the cat. When the cat starts to take the initiative to approach the new owner and rub its body against the new owner's legs, it means that the cat has recognized the new owner.
