Do all creatures have hearts

No, every living thing does not have a heart. Plants are living things, and they do not have hearts. Animals, fish, insects, etc, will have a heart, or another organ that performs the same function.

Answer 2

Well, as far as anatomy goes, of coursel They have a heart that beats like any other mammal. I have always disagreed with people who say that they have no soul. I have four cats and they are all special to me, and I love them all. I just find it impossible to believe that they don't have a soul and heart. It is not possible for me to look any one of them in the face and think that they are soul less or heartless. --Kate J--
