I ordered 4 Smarty Kat sweet greens as I had a couple of times before. So far 2 of the greens didn't grow any grass at all. I thought I did something wrong with the first one so I did another one, and still no grass. I have used this product for years and this never happened. Is there something different with this product? Thank you

The best cat grass yet!

Once I grow it, the way the instructions say, I transplanted into another container with holes in the bottom and just keep it watered lightly and keep it in the sun. The cats love it and can have it at any time. It lasts for a long time this way.

USED to be good but not anymore!

Had one not growing and another with some gross stuff on the seeds so contacted support here and graciously sent two new ones. But I have now tried 3 others and not getting any growth at all, trying half of a 4th one in water to see if the seeds will even germinate that way as they aren't the usual way! Used this same brand for 10+ years and had some issues a year or so ago but they did eventually grow something even if it was sparce but these now are not growing anything at all! NOTHING! Not even one blade! My poor 15 year old cat has been without grass for two or so weeks now! I'm disabled and can't get to anywhere to get grown grass and can't afford to do another order for either more of these or to try the other brands! IS there some way to get these to grow or are they all duds now???????

I had bought another brand here and it turned out excellent, it’s sold out and I tried this one. I bought 3 packages thinking it was as good as the other one, but none of the 3 grew. and now that I read the comments I see that it is a bad brand. don't waste your money!!!

The quality of this product is terrible now. It used to grow quickly and last for at least a week. Now it will barely spout and gets moldy. We had two containers do the same thing. Very disappointed and won’t be buying this again.

Normally Good, but . . .

I've ordered these many many times and purchased them from brick and mortar stores, too. However, this last order, when I got three of them . . . TWO of the three never grew. I followed the same process I have dozens of times before, and one grew great--taller than usual, in fact--but the other two NEVER GREW AT ALL.

Grass did not sprout.

I ordered two of these for my cats and after following directions, the grass did not come up. Have used this brand before and always had a bowl full of grass that they loved. These two were duds. My kitties have missed having their grass!

Never grows!

I don't usually write reviews but this must be said: I've bought two of these over time, followed the instructions, and they never grow. A waste of money. However, I highly recommend SmartCat Kitty's Garden which grows quickly and my cat's love!

Sweet Green Grass

I did exactly what the directions said, it's not growing much at all. I'm highly disappointed in the way its not growing. I'm so glad I didn't get the bigger container.

I wish I had read the reviews before I purchased SmartyKat Sweet Greens Cat Grass. I followed the directions carefully, and the grass did not sprout. What happened instead was mold.
