My Oscar will chew on anything. He has chewed the strings off a couple of pajama pants and hooded sweatshirts. He chews on boxes and hair brushes. I even saw him try to chew the flusher knob on the toilet once (yes, it is metal). He also always chews on a metal lamp I have. You would think he's a puppy. He is about a year and a month old. Oh yeah, the other thing he chews on is the blinds in my bedroom window. He has chewed him and his sister Lucy a lookout so that they can lay on the bed and see what is happening outside (see picture below). There are even more slats chewed off now. Does anyone have any ideas on how I can fix this behavior? Now, Lucy does not have this problem. However. . .she does chew on my toothbrush frequently. HELP!
