Are you interested in building your own apartment buildings?

I just had another thought. In the sims 4 cats and dogs, are there not doormats that keep out certain types of pets? "No Other Families Allowed" (or something much less stupid, lol) on a mat would work wonders.
I really think expansion packs should have sequels/reboots. Like City Living 2 (but it doesn't REQUIRE a player to own the original city living), and the whole thing explores a different city with a different apartment model, etc.
