The end of your entry should look like !;!;!;!;: Then, hold [Enter]. The "No such cheat" message will flash. Hold [Enter] to quickly get up to 9,999,999 simoleons. 

Full need meters:
If your Sim is very depressed or has another low attribute, enable the move_objects_on code and pause game play. Click on the Sim in buy/sell mode and click the bottom of the screen to delete him/her. Once deleted go to the live mode and double clock the person's head icon to go to where that Sim is located. Everything should be close to full. Note: Wave the game immediately before performing this cheat, or you will lose any career changes or points you have earned. 

Breeding animals:
Unlike Sim babies, you cannot delete the parents and children. Allow the computer run for three Sim days and the kitten/puppy will grow up.
