The idea that companion animals make people happier and healthier is called the pet effect. Study provides reasonably strong evidence that taking care of pet crickets caused impressive reductions in depression and more modest improvements in the cognitive functioning and quality of life of elderly people. Compared to dogs and cats, crickets are inexpensive and easy to care for. They do not require much space, and they can be raised indoors. Thus crickets are ideal pets for elderly people, particularly those with limited mobility or who don’t have the money for the care and feeding, of, say, a dog.
