Old people can keep cats
Some old people sometimes feel lonely. I think they can keep cats as their pets.
First, cats are not very big and they don’t eat too much. Old people don’t need to make them big houses or spend too much on the cat food. Second, cats are very clean and easy to take care of. Old people don’t need to clean the house very often. Third, cats are good companies. When old people watch TV or rest on the sofa, cats are always with them. They make old people’s life much happier.
