There are many reasons why cats might poop on the bed. One reason is as a form of revenge. If a cat feels neglected or treated unfairly by its owner, it might choose to defecate on the bed as punishment. Another reason is an unclean litter box. If the litter box isn't cleaned regularly, the cat might choose to defecate elsewhere.
Cats are very loyal animals. If their owners take good care of them, they will consider their owners as family. Cats are also very intelligent animals; they can read people's expressions. When their owners are sad, they will sense their emotions and offer comfort. If a cat considers its owner as family, it will show gratitude by placing a mouse it has caught on its owner's bedside.
