Hard cover for Genos 2

[Ray]

I have two indoor cats, and as cats do, love walking over furniture. I have a Clavinova, which as you know is cat proof with a lid over the keys. But would love to have a Genos, if any one has any ideas, short of getting rid of the cats, of a hard cover to protect the Genos top, once the two speakers are removed. Perhaps an unusual query, but maybe other members may have this issue, or an answer. Thankyou.
