What else can i do on the Sims 2 Pets?

well, the sims 2 pets comes with lots of new items, clothes, interactions, and things. But its an add on. Its for people who have been playing for a while and want new stuff. Maybe the sims 2 isn't your type of game, because there's way more to it than that. You control a family or just one person. What do they do, why, do they forget about their toddler and does the social worker come? blah blah blah blah...
