You have opened up your very own pet shop where you are taking in both puppies and kitties. the customers will come in and sit in the waiting room. take their pet to the working station and give him the treatment they ask for. in the first level you will be only able to brush them, but as you progress in the game new cool options will appear, like brushing their teeth for example. when you are done, give the pet back to the customer and they will pay in cash in return. just make sure you do all of these actions fast, before the customer gets impatient and leaves. every day you have a target of money you will have to achieve before the time runs out. you can see your timer, money and your target in the bottom part of the screen. good luck playing pet shop puppy and kitty!
