It was bad before we open them. I saw them when we got. I did open. It had some spot green color. I did not know what it was. I was very upset. Do not buy this product.

these chips are good, and bad, and create moral dilemmas constantly. If wou are strong at will, or having a large BBQ go for it, but as for me, i was in the habit of bringing a new bag to work every three days, had to put in a lot of time on the treadmill to make up for it. BEWARE

Cat grass is cat grass, and I have one cat that absolutely loves it; another that couldn't care less.  It's winter now, so I couldn't find it where I buy seeds, so I went on line.  Product is okay, service was prompt.  My disappointment: could only order one two-ounce package per shipping and handling fee.  Cat grass only lasts a couple of weeks, and I would have ordered 3 or 4 packages, but not at 3 or 4 times that shipping fee!
