I bet you have too many pictures of his nose and whiskers!The strap on my digital camera. Every time I try to take a picture he goes for it. Sometimes it results in a good shot, but usually it doesn't.
A while back I found an older broken camera I never threw out and stuck the strap onto a piece of string to make a toy. He would have none of it. He's only interested in the strap when it's attached to the camera.
