Song Lyrics and Leaf Chips

I had the radio on during cookie making the other day. Marina was singing along to "Maneater" by Hall and Oates. Here are her lyrics:
Whoa-oh here she comes,
Watch out boy, she'll chew you up,
Whoa-oh here she comes,
She's a Mad Beaver....
And here I was worried about the effects of certain song lyrics on her impressionable young mind...
Our older kitten, Guru (guess he's a cat now) has taken to pulling dead leaves and flowers off my plants and eating. They're so crunchy, it sounds like he's eating potato chips. I haven't decided whether I should discourage him or not. At least it's less plant maintenance for me. If anyone who has animals knows of ill side effects from eating dried up plant matter, please let me know. Oddly, he doesn't go after the greens like the other two cats. I guess he doesn't like the chewy texture.
