Mac, your Cat doesn't blink anymore because his skin is too tight.
You should have poked a couple of holes in him before you put him in the microwave. (your lucky he didn't explode).
All you need to do is poke a few holes in him to let the pressure out and then microwave him again for 5 or 6 minutes.
That should get him blinking again!
cheers, and glad I could be of help to you!
