I grew this grass from a grass-kit as I could not get any viable wheatgrass seeds myself. It took about 5 days for the grass to be this height. Tanaka likes eating grass in this way as he has a hard time trying to adjust his whiskers for cut grass. Bujang prefers cut grass. Skywalker is curious about grass. She may not have been given any previously. She likes the smell but she is confused as to why Tanaka enjoys eating it. So she scrutinizes him every time he eats grass.
