A 50-day-old kitten will recognize its owner. Kittens begin to recognize their owners when they are about two months old. It is relatively easy for kittens to recognize their owners. The owner can often feed the kitten its favorite food, play with the kitten, and train the kitten's eating and toilet habits. Soon the kitten will recognize its owner.

Notes on training kittens:

1. Kittens have limited intelligence and can accept limited things. When training kittens, do not give them all at once. Cats impart too much knowledge.

2. When training kittens, pay attention to the training environment. Do not let cats stay in noisy environments for training. Kittens are easily distracted by external interference, making training more difficult.

3. The owner should control the training time when training the kitten. If the time is too long, the kitten will feel disgusted with the training. Try not to exceed 20 minutes each time.
