Many veterinarians, including nutritionists and behaviorists, believe it is important for dogs and cats to express their natural foraging and hunting behaviors. For pets living indoors, this can be difficult, and the lack of this stimulation can sometimes lead to behavior problems. Enriching a pet’s environment with food toys and puzzles at mealtimes can fulfill the need to forage. The use of toys, puzzles and other novel methods of food delivery can also be effective ways to increase daily movement in overweight or inactive pets.
