Cats themselves cannot speak because they do not have human-like language abilities. If you are referring to language training your cat, then there is no harm in this. However, because cats’ brain structures are very different from those of humans, they may not be able to understand or express human language.
If you want to communicate with your cat, it's best to use your cat's own language, which means using body language, sounds, and behavior to express itself thoughts and feelings. For example, you can observe your cat's body language and sounds and understand what they mean so you can better communicate with them. At the same time, you can also learn some common cat behaviors, such as ear scratching, back scratching, etc., and understand their meaning so that you can use appropriate behaviors when communicating with cats.
