The reason why the kitten keeps meowing
1. Hunger: If the owner does not choose to feed the kitten small meals frequently when it is very young, the kitten will get hungry very easily and will meow to tell the owner that it needs to be fed.
2. To attract attention: When a kitten wants to get its owner's attention, it will choose to meow to attract the owner's attention and thus get the owner's attention. 
3. Illness: If the kitten is sick and feels unwell, it will cry constantly. The owner needs to take the kitten to the vet for examination in time.
4. Heat: When a cat is in heat, if the owner has not spayed or neutered the cat and the cat has not found a mate for mating, the cat will keep meowing to show its need for heat.
5. Environment: If a cat is in a new environment, it will experience stress due to unfamiliarity with the environment. At this time, the cat will keep meowing. The owner needs to prepare a comfortable cat bed and let the cat explore on its own. It will stop meowing when there is no aggressive behavior.
6. Stress: If a new pet joins the household, the cat will feel threatened and will choose to release stress by meowing.
