We all know that presence of a pawed pal can alleviate stress like anything. But cats, they do it so much better. They're known to have a positive effect on your mental health, so no worries there. While a cat can easily get frightened, they can actually lower the risk of heart diseases. If you have tiny tots, then get a cat already because this feline creature can battle all kinds of infections and help children with autism become socially interactive.
