The Sims 2: Pets Glitches

Have a 7 Creature family!!!!
Normally you can only have 6 people and or animals. Get a full family, and let one of them starve. The pet will run away and you can go to the towns square to buy a new pet. When you get home report your lost pet, eventually your pet will be returned. Ta Da, now you have more creatures in your family... you can repeat this if you want even more.
