Plants are beautiful decoration to have around the house, giving a natural ambience to the surrounding. Some cats even go crazy with plants such as "catnip" [actual name: Nepeta catara], rolling around it like no end. Some cats also developed a nibbling habit on plants. Nibbling away any plant they could get their paws on. One way to manage such behaviour issues is to buy or even to grow your very own "cat grass". This help to divert their attention from the foriegn plant to the "cat-grass", which is more desirable and provide some benefits to the cats.
Here are the 3 types of "cat grass":
