Stalone's gastronomical affection to cat grass comes and goes as it pleases.
The very first pot of wheat grass, I got him in Whole Foods, went directly to the trashcan, after being abused by Shiva as a toy.
After that I decided, that not all cats need grass. Up until cats decided that they have some unfinished business with the only plans managed to survive my handling - 2 small pots with violets, which are quite lovely by the way, but in no way are they suitable for cat consumption.
After 3 more of less successful attacks, and failed attempt to find some place where violets would still get some sun but no cats within my reach on first floor... Violets migrated to an upstair room furnished by a door, and I decided to make a second attempt on cat grass...
I've been somewhat successful growing Cosmic Kitty Herbs (barleys, oats and wheat mix) which gave a nice vegetation and Stalone was amused by it for a while; I also tried 3 Packages of Cat Grass Seeds 1 wheat, 1 oats, 1 barley for your KITTY, for which I did manage to mess up the seeding process (it only gave couple of sprouts), but somehow Stalone loves to munch on them. See for yourself ("3 Packages..." pot is in front and "Cosmic Herbs" are behind Stalone on photos).
To be completely fair, I must say that Shiva uses any cat grass as a play toy exclusively.
