While there is no definitive research on the topic, some studies and anecdotal evidence suggest that cats who have feline companionship may experience certain benefits that could potentially help them live longer. Having a feline friend can provide cats with social stimulation, which can help reduce stress and anxiety and improve their overall well-being. Cats who live with other cats may also be more physically active, as they may engage in play and other social behaviors that can provide mental and physical stimulation. Additionally, having a feline companion may help prevent some of the negative effects of boredom and loneliness, which could potentially impact a cat's health and quality of life. That being said, it's important to note that not all cats get along with other cats, and some cats may prefer to be the only pet in the household. It's important to carefully consider your cat's individual temperament and social needs before introducing a new feline companion.
