I suppose you (or such an inclined friend) could macramé smaller than usual thread size (say 1/8th inch) jute corded curtains to hang in front of the sheers. Would take kitty a very long time to shred those. If you don't know any such friends, I'm sure someone like that is findable on the net. Might be able to crochet it with a big enough needle.
