pounce over to the Rainbow Scrappy Challenge.
For an example of using sew-in centers, see this post about two Dear Jane blocks. I use the Dale Fleming method for the six-minute circle which I explain here. The method as applied to owl eyes is discussed here.
While she wouldn't eat her breakfast, that morning she did chew a hole in my silicon sheet that I was going to use in the demonstration. That's when I reiterated to her that I will not take her to the vet for a gut obstruction given her love of chewing plastic and paper. I would be willing to set her up for brain surgery to rewire that part of her brain...or even remove her naughtymus, the part of the brain where naughty behavior originates.
Needless to say, she has rebounded and has made up for lost time in eating, cuddling and racing around the house in crazy mode.
