Kittens may be meowing a lot for the following reasons:
Hungry: Kittens will meow when they are hungry and there is no food. Because kittens have small stomachs, they can easily remind their owners when they are hungry by meowing.
Boredom: Kittens will meow when they are lonely or bored. Because kittens are naturally active and playful, if they are confined to a cage for a long time or have no toys to play with, they will meow to remind their owners.
Cold: Kittens will also meow when they feel cold because their fur is sparse and they are easily chilled in cold weather.
Protecting themselves: Kittens will also meow when they encounter danger. Because kittens are small, they will use meowing to protect themselves when they encounter danger.
