The Genius trait and the Fast Learner lifetime reward will cause your pets to learn other traits more quickly. Eventually, you will get a message saying your pet has learned the Neat trait and this challenge will be completed. After choosing this option 2 or 3 times, wait for your pet to Pee Outside on its own and then praise it for doing so. For instance, to add the Neat trait to a pet, you can control your pet and have them Pee Outside. However, you can choose the option for the pet the first few times, and then praise or scold the behavior to finish the training. This trophy requires a pet to learn a trait using the first method.
Secondly, if you are controlling a pet, choosing an option for the pets reinforces that behavior. First, if a pet acts autonomously and chooses its own action, you can choose to praise or scold that behavior as a Sim. Good Fluffy! Praise or scold a pet enough times to add a trait.
