The reason why cats keep meowing when no one is with them is because cats lack a sense of security. It may be that the cat received unfair treatment in the previous owner's home before this owner left. It could also be that the cat was separated from its mother right after birth. This causes the cat to feel insecure. Cats are most insecure at this time.
