Barnie so loved the idea of an Invisi-cat Shield. However, after discovering that the first Invis-cat shield was defective, he found a much better model.
Oh yeah. THIS Invisi-cat shield really works. He is completely invisible to human eyes, but can still see everything and everyone perfectly through this shield.
Watch out, unsuspecting humans who need to use the shower or bath tub!
(He has been sitting here for a while. Note the little wet “noseprint” on the curtain. Also invisible.)
