The original plan for The Asbestos Palace was to have it gutted while we lived elsewhere, alas the vagaries of our flamboyantly named yet completely ineffectual solicitor among other things, conspired for us to be in residence from the moment of completion. As they say, no moving plan survives contact with the English house buying process.
Anyway, it came with a splendidly awful coir carpet. The only entertainment to be had from that foul, foot-grating floor covering was the watching the cats apply their brakes and stop so suddenly that their souls reached the other side of the room before they realised they'd left the body behind. It worked for people too, and you didn't want to fall face first on that stuff, not if you planned on retaining your face.
Now the cats have a slippy hardwood floor which they further distress to their inevitable delight.
