Cats are wonderful companions. They are independent, yet considerate. Clean. Affectionate when they want to be. You have to approach them gently and build their trust. Each cat has his/her own personality. Some are very shy and others more social.

I think there is a reasonable explanation as to why building a relationship with them helps to have a healthy heart. They require you to calm down to allow them into your space. They are a great model for relaxation and quiet. Their purring has a great psychological effect on our mental state.It is a calming device.

In most cases, cats get along with one another amicably. Catfights among domesticated ones are rare. They often enjoy one another playfully and are highly entertaining particularly if you play with them and give them catnip.

Cats appear to be heart-healthy and it's contagious for us humans.
