A cat's tendency to hog a pillow can be caused by several reasons:
1. Comfort: Pillows are usually soft and supportive, providing a comfortable resting place for cats. They may find pillows more suitable for napping or sleeping than other places.
2. Warmth: Pillows are great for keeping a cat's body temperature, especially in colder environments where cats may seek out places that offer extra warmth.
3. Sense of security: Cats are territorial animals and like to rest in high places or enclosed spaces, which makes them feel safer. Pillows often provide a sense of envelopment, making cats feel protected.
4. Habit: If a cat has been used to sleeping on a pillow since it was a kitten, it is likely to continue to do so because it is a familiar and comfortable behavior pattern for it.
