I have to say that Cosmic kitty herbs are the best thing ever, and as you can see by the video, my cats love it! In fact so much they can get a little greedy and pushy about it sometimes as you can also see! LoL
Seriously though, it's a great source of greens for your cat, especailly if they love to nibble on your plants! Now they can have a plant of their own which is a health blend of selected special grass varieties. You can grow as much or as little as you would like. I can plant about 3 to 4 8" pots out of one package, and it grows very quickly.
Simply fill the pot with some good planting soil, sprinkle the seeds evenly over the top of the soil and lightly water, Keep soil moist...not wet, and set in partial sun. When plant starts to sprout set in full sun, and as it grows taller, let them enjoy it! I bring my cats plant in once a day for about 10 to 15 minutes so they can snack, then it goes back out on the patio, because I know my cats, they tend to gorge on something they love, and too much of a good thing can be bad! If you have a occasional nibbler than I suggest you leave it inside in a sunny spot so they can enjoy whenever.
This definitely is a great way to provide your furkid with a source of chlorophyll to aid in digestion, and is a natural source of vitamins and minerals. So go and grow some of this for your kitty, you'll be glad you did!
