Most cats enjoy eating grass particularly anytime they have an upset tummy and my cat is no exception to this. I got this for my kitty Littleman and he loves it. It comes with everything you need including organic wheat grass seeds, soil, and vermiculite. It is designed to be planted in the middle of one of those toys with the ball in the track that goes around the outside of the hole in the middle. It was simple to plant and I had wheat grass sprouting within the first week I had planted it. He loves munching out on his wheat grass and I don't have to worry about him eating something that isn't good for him like one of my houseplants. This is a great gift for any cat owner.
