I have the exact same problem. Just thought I'd say, but I can't help. Sorry and good luck(:Can i use all the Sims 3 expansion packs at the same time?
Yes. When you install new expansion packs, the old ones are all still installed. So if you installed World Adventures, Ambitions, Late Night or any of the other expansions, you will still have pets in your game. Essentially it is like all the games are combined into one larger game when you install expansion packs. Also, keep in mind that the disc you use is to play is always the disc of the newest expansion you have that was released by EA, which is not necessarily the same as the last one you installed. For example, if you get World Adventures, even though Pets is already installed before World Adventures, you will still have to use Pets disc to play because Pets is newer than World Adventures (if you don't know the order that the games were released, just stick any disc in and when you start it it will tell you if you need to use a different disc)
