Humans have started to domesticate cats thousands of years ago, so cats have a long history creating bonds with humans. Humans who have a special bond with a socialized cat are very fortunate, as cats can be wonderful companions. They are incredibly sensitive beings, can give comfort to us when we are stressed or sad, and make us laugh with their funny antics. Each cat has his or her own, unique personality, and interacts with their human in their own way, using sounds, body language, any their eyes. The sounds that we perceive as “Meows” were developed by cats over time solely to communicate with humans; and in time cat owners know quite well how to interpret their cat’s “language”.   Scientific studies indicate that cats' purring has beneficial effects on both cats and humans, primarily by reducing stress and promoting relaxation. The low-frequency vibrations produced by purring can lower blood pressure, reduce anxiety, and even aid in bone healing. These effects are linked to the release of endorphins and oxytocin, hormones associated with happiness and stress reduction, in both humans and cats. Cats can also be territorial and act on their instincts, and while they adjust well to living with humans, their minimal needs such as hiding, scratching and climbing have to be fulfilled. When more cats live together in a household, there are hierarchies in place; and just like with humans, while one cat can be relaxed and easy-going, another can be bossy, and when introducing a new cat to the family, “smooth” relationships are not always guaranteed from the get-go. In any case though, cats create strong bonds with their human- and cat family  members, and their known environment; they become true family members and enrich our lives in their own unique ways. Each cat has the potential to be a wonderful companion to a human’s life, and in turn deserves to receive care, protection and love.
