The animal interface is tied into how your Sim gets on in life. The pet salon is your main source of income, and in order to make good money, you must tend to other pets that customers bring in. You get a notification that a new customer wants pet service, at which time you have the option of taking the elevator down to the salon on the ground floor. You can use touch screen to perform tasks like clearing up fleas, picking a new collar, and eliminating funky odors from the pet. If you don’t want to be bothered with cleaning up someone else’s filthy pets, you’ll still earn money, but it won’t be as much if you take charge of your shop and do things manually.
Clearing up fleas, eliminating funky odors…That doesn’t sound like a game I want to play! In fact, I’m in the process of doing that now with a cat we adopted from the pound!
