Cat Spa is a game where you can play as a spa owner and manage your own salon. In this salon, you can do whatever you want. You can decorate, unlock new rooms, and even have your own restaurant. Your spa will be filled with clients who will all have different needs. Some will want to get a massage, others will want to get a facial, and some will want to get a manicure. All of these clients will have different requirements.

Your spa is going to be filled with a lot of different clients. The most important thing is that you need to be able to handle all of them. 

The game is a simulation. So, you can’t really “pay” for anything. However, it is a good idea to try to maximize your profits. You can make more money by doing more treatments, and by unlocking more rooms.
