Cat-About by MiracleCorp Gimborn Single Cat Grass Plus, 60-Gram

I have purchased this product twice and though the grass grows quickly, it dies just about as quickly. My cat does frequently go to the grass and chew on it, but I hate having to replace it after only a week or so. Would rather have something I could continue to water and have last longer. The initial price is reasonable, but not if I have to continually replace the product.
