Food puzzles are a good way to challenge companion animals, according to an article on  Good Morning America's website .

Today's house pets are used to eating by going to a bowl already filled with food, which does not challenge them mentally or physically. Animals should be driven to use their minds and bodies to earn food instead of expecting it. Food puzzles are toys filled with small treats or food that encourage dogs and cats to work to get to their food. This can help to release the animal's energy and improve memory, according to the article.
