Awww, poor Rudy, he looks so guilty and also like he is feelin' so bad about things at the same time.
I used to have a siamese cat that would chew on some of my favorite plants.
He just wanted my attention and didn't dig the fact that I was also taking care of and paying attention to something else other than him.
I noticed that if I would sit and stare at some new growth on a cherished plant, and if he was there watching me do that, within a day or two, he'd make that plant pay, with bite and chew marks.
Pets, hahaha, ya gotta luv 'em.
