You don't create the pets, you adopt them at the adoption center. Or, if you wanted, you could take your chances at the pound. There are new pets every month in the "Adopt" section of the website, and then they grow into adolescents and then adults. They are free, so don't worry about any payment required. So, to answer your question, you don't create them--you adopt them. Good luck! :D
