Oyen eating grass

Remember the grass that I bought for Oyen the other day?

Well, I planted it already, and it started to grow. It is not fully grown yet. This is how it looks on the 5th day after I first planted the seed.

Anyway, I put the plant outside my living room window. And just about now, I saw Oyen climbing to the spot, and start sniffing the box that I use to plant the grass. He tried hard to reach the grass.

So, I took the box, and place it on the coffee table, when Oyen keeps sniffing the grass, and suddenly, he started to chew on one of the grass blade. I quickly went into my bedroom and get my digital camera. So here it is Oyen eating the grass.

It really amazes me with the fact that cat instinctively knows that grass is something to eat to help with the hair ball problem. And I keep wathing Oyen in astonishment as he keeps chewing on 3 more blades of grass.
