It may seem like a pain to feed your cat from anything other than his bowl, but food puzzles can really play to his instincts. Having to chase a ball with holes in it to retrieve his food or manipulate a gadget to get hold of his kibble can really help a cat deploy his natural hunting instincts, which he needs to act on to stay psychologically healthy.
Researchers have found that food puzzles can reverse a variety of both psychological and physical problems. Obese cats have lost as much as 30 percent of their weight by learning how to eat from food puzzles. Food puzzles have even helped cats to stop urine marking, nighttime vocalizations, and depressed or anxious behavior.
