This is one of my favorite things that Rocky does, but I have a hard time getting a good picture of it! My camera is not powerful enough to take a good picture from far away (hence the evil glint in Rocky's eye), and if I get too close, he just comes out to threaten me. He only does this for a portion of the year, so I have to enjoy it while I can.
This next picture I took this morning. Rocky's been screaming pretty much non-stop, unless he has a box to chew. I gave him a new box this morning so I could get ready for work in peace. As you can see, he chewed an entrance hole in the bottom left of the box.
When I found him, he was inside the box and stuck his head out to look at me; however, when he saw me, he had to run over to threaten me, which is what he's doing here. Once I left him alone, he went back to his box.
By the time I left for work, he'd chewed through the entire front of the box. I'm sure it will be gone when I get home from work.
