My two love the cat grass - better for them to chew on that than on my plants as they do when the cat grass dies down. The organic wheat grass is less pricey than the cat grass at Petco, but they don't seem to like it as much. Picky kids! I'm going to try growing my own again - I used to do that for my RB Goldie, but she was never too crazy about it. I remember it was very easy to grow, just didn't last too long.
