This is a really fun game, all you have to do is post things to do in the Sims 2: Pets. Post as many as you like in one go. For example, someone could post numbers 4, 5, 6, 7, and the next person would post 8, 9, 10, 11, 12, the next would post 13, 14, 15, etc...
I remade this as the last version was full of flaming and unorganized.
Okay, I'll start. These are my ideas from the previous thread.
1. Become best friends with every Sim
2. Get rich people to move in, then kick them out
3. Build a mansion on every empty lot
4. Marry Hilary Duff
5. Experiment until you find a totally awesome food recipe
6. Get your Sim's blog to 100% popularity
7. Have a huge party, anyone who isn't there invite round personally using the phone
