Pets and Supernatural have pretty consistently been my favorite expansion packs since the original Sims. I'm very excited that modders are finding code for pets. It would be nice this time if they had more than two sizes of dogs. A Chihuahua and a beagle are not usually the same size... I also loved the unicorns in Sims 3; it fulfilled a lot of childhood wishes for me. But I could see horse-y stuff being a GP separate from the Pets EP (which may be a good thing considering how cool vampires turned out).
