To get cats to come visit you, you need to leave out food and some toys for them to play. Tap the bowl of food to refill, or if you want to exchange your food for something more high quality, then go to “goods” and pick the food you want to replace with the existing one. Food will run out eventually, so check every few hours to refill the food. (If you extend your house, be sure to put food in the other half of your house, too.) You will want to check the app occasionally anyway to you can catch some cats to log into their profiles. If you miss a cat, they’ll show up as a silhouette in their profile until you’re able to see them in action.
