The reason why cats like to wake up their mothers may be because they have some specific needs or wishes that they want to satisfy. For example, your cat may want to eat, drink, go for a walk, or want your attention and companionship. In these situations, your cat may use various methods to get your attention, including meowing, scooting, jumping, or clawing. In addition, cats may wake people up out of habit or other reasons. Some cats may wake you up at a specific time, such as six in the morning, because they think it's meal time.
Some cats may even wake up at the same time every day, although this time does not have any special meaning. Generally speaking, the reason why cats like to wake up their mothers may be for various reasons, including needs that need to be met, attention that they want to attract, habits or other reasons. If your cat's meowing bothers you, you can try to take some measures to avoid or alleviate the situation, such as feeding your cat regularly, providing it with enough water, or providing it with appropriate activities to burn off its energy.
