I purchased the "SmartCat Kitty's Garden" original and an extra refill. The product performs as advertised, producing grass my cat loved and voraciously consumed. This is a good product; however the growing space is limited to 4 small pockets and the grass does not last very long due to the root system becoming "root-bound"; thereby choking any chance of long-term growth. Because of this fact, I decided to order Cat-Grass, Sweet Oats and other seeds in "bulk" and plant them myself...so as to have plenty and sustained growth over a longer period of time.

HOW TO: (1.)Select a receptacle, which has good drainage, and is about 3 to 4 inches deep. A square shape is best so that your cat can't tip it over or push it. (2.)Fill the receptacle with dirt or peat mixture. (3.) Spread and plant the new seeds about 1/8 to 1/4 inch deep ... making certain that every seed is covered with dirt. "Lightly pack the dirt" ... don't press hard... allow the shoots access to grow. (4.)Water... (not soak)... and cover the container with a clear plastic...(like a big Baggie or Dry Cleaner's plastic bag). (5.)Be sure to use a "fork" to poke about 30 to 40 small vent holes in and round the plastic. This creates a "Hot House" effect and prevents mold. (6.)Place container where it will receive good, strong sun-light during the day and not freeze at night. In about 5 to 7 days you should experience growth.

Let your Cat have at the grass when it reaches about 3 inches in length. I lightly spray with water and re-cover the grass with plastic every other day or so to stimulate growth and peak my cat's interest. When grass no longer grows... and this will vary according to your planting and care methods... simply use new soil and replant the grass by following the above instructions. The good thing about buying in "bulk" is that you can experiment with different growing methods and not lose money while doing so...Good Luck!!

I bought this kit for my cats after buying them cat grass at the farmers market. They went crazy for it and the next time I went to market they were out of cat grass. Coming home emtied handed was not an option for my cats!! I bought the kit and it is a no brainer. The grass comes up in a few days when put in sunlight. It takes about a week to get it up to the size for the cats to enjoy and it last about a week. It is worth it to see them devour the first blades when I put it out. My cats are two full grown 20lb kittys! They would live without out it but really like having it to munch on. The combination of oat, rye, wheat and barley must make it tastier than just the oat grass that I get at the farmers market.

This kitty grass grows fast and it's easy. Once they stand 3 inches, give to your cat, because it will start to wilt in about a week. I sometimes use half of each bag of seeds because my one cat doesn't use all the grass.
