I don't get it. Cats have some sort of stigma towards plants. My little kitten scratched one of my buttons. I saw her do it. She pawed at it, kinda like she would if she was seeing if something was "dead or alive." She pawed at it kind curiously, like it was a dead mouse. There are four "claw" marks, deep razor like cuts. Why!?! I asked her. Why? The button has gotten far over it and healed up nicely, just scarred.
I always find my kitten chewing leaves of various houseplants; she just loves catnip. I try to give her the catnip so she'll stay away from my plants and dried herbs. It doesn't work very well; I always find her head in a big jar of pot leaves, munching away. No joke, fresh or dry she loves pot leaves.
