There are several possible reasons why cats like to step on pillows:
1. Seeking comfort: Cats are naturally inclined to seek out comfortable places to rest, and pillows, due to their soft and warm properties, can provide an ideal resting place for cats.
2. Sense of security: Cats seek out safe places to rest when living in the wild, and at home, a pillow can provide a similar feeling, making cats feel safe and comfortable.
3. Habitual behavior: Cats may prefer to rest in certain places due to habit. If they are used to resting near a pillow, they may continue to maintain this behavior.
4. Seeking the owner's scent: Cats are very sensitive to their owner's scent. They may look for their owner's scent near their pillow because it makes them feel safe and comfortable.
