How many cats can you get in a Sim year? You need cat hangout and the fertile trait (this trait also works on animals) for the lot. For your sim, you need cat lover and erratic (to really be a crazy cat lady). Turn off the limit of sims in your household. Start off with as many cats as you want, become friends with the strays, and adopt them. To make it really challenging, only have 2 or 3 feeders and litter boxes total in the house and on the lot. #crazycatladychallenge #deligracy
