To answer a forum question. Type in the name of an animal and then press Space. The smart cat will tell you the favorite food of the animal. The way it works: As you type, letters are added to the Search Animal variable (with spaces in between because of the way List concatenation works). When you press space, the project loops through the Animals list looking for a match with the Search Animal variable. It uses the variable Index to keep track of which list element it is currently looking at. If a match is found, the favorite food is gotten from the Favorite Food list by using the value of Index.
