Do you lack joy, profit, or food?  There are not many ways that you can have all of these things at once.  However, there is one great way to have all of them at once.  Just buy two pets that can mate.  When you play with both of them, you can have fun.  When they have babies, you can sell them and raise a profit.  Or when the pet lays eggs, you can eat the eggs for food.  One reason why people keep a pet, is to reduce their loneliness.  If you live alone, you are probably lonely.  However, if there is a little fellow next to you, then you will not be lonely anymore.  When you return home from work, you will open the door, and your pet will welcome you more than anyone else.  If your pet is a dog, it will come to you wagging its tail.  For example, my old dog Bagel licked me and wagged its tail once when I came home.  I really loved it.  It is important to take care of your pets with real love.
