Dogs are good for children because they teach children to be responsible. Children who have to feed the dog and perform other works related to dogs, learn to be responsible for the life of another being. Cats also teach children responsibility, and along with this, children who own a cat learn about independence since cats are quick to teach this. Rabbits teach children about having babies because as anyone who has owned more than one rabbit knows; they have a lot of babies. Snakes, rats, fish and gerbils are also good to teach children about cleanliness and proper bathing habits. Most pets teach children valuable lessons.
