I found these little containers of "cat grass" seed at Wal-Mart and decided to try to grow some for Speck. I wasn't sure if he'd be interested in it and wasn't convinced I could get it to grow. I'm not the greatest farmer on earth. However, I followed the planting directions and then put it in my walk-in closet (which has a window). To my surprise, it started to sprout. This evening, I was putting some Christmas gifts in the closet and I left the door open. Speck was watching me, but I had no idea he'd found the cat grass. The next thing I knew, there was dirt in the closet, a trail of dirt in the hall, and he was eating a clump of cat grass. He seems to love it.
