I absolutely love this game! It is so fun to play and the pets on it are so cute! It is fun to name and dress all 20 of them. You can unlock twenty pets buying earning kibble(money) and purchasing them from the adoption center. If you want pet number 21 then go to the options tab and enter the password: LPSTRU It unlocks the last pet the giraffe. I am 14 and I still absolutely adore this game and LPS. I HIGHLY RECOMMEND IT! WORTH THE MONEY!!!!!!!!!
