Dogs are considered the best friends of man, and we fully agree with this, because they are loyal and honest with their human friend, and are also excellent babysitters for young children. But a cat can also become a great purring companion for your child when she is not thinking about an insidious plan to conquer the world. Although cats are great pets, make sure that your cat is friendly and your children understand the boundaries of what is allowed, going over which you can get an unpleasant scratch.
