Does cats know they are cats? Yes, except for pet cats trained by humans, most cats know they are cats. Research shows that cats use their body language to indicate their personality, and these signals may also be manifestations of cats’ perception of themselves.
Most cats do not know that they are cats, because cats are not as self-aware as humans, so many of their behaviors are caused by nature. Self-awareness is a high-level self-cognitive function, and humans usually only have this cognitive function after 8-18 months.
Some cats with high IQs will know that the cat in the mirror is itself, and they will realize that it is different from their owner's appearance. This kind of cat already has a certain degree of self-awareness and can distinguish itself from its owner.
