Retirees are increasingly keeping pets, especially smaller dogs and cats. Many retirees find pets help reduce loneliness and stress, and provide companionship. While some research suggests pets can improve health, other studies have not proven health benefits or shown risks like falls. However, attitudes are changing as more retirees want pets, and more retirement communities now allow pets. Retirees are also highly devoted pet owners, spending over $1,000 annually on pets, and considering pets in their financial planning.
