I was looking for an easy-to-grow, foolproof grass-growing kit - and this is it! You take the package, punch a few tiny holes in the bottom, pour in the provided seeds, water it and - voila! - just wait a few days and your cats will have delicious grass spears to munch on. You can cut the grass or have the cats eat out of the bag. My only complaint: a bit expensive (thus 4 stars only). I wish these packs came in larger quantities at a discount.
