On the scratching post thing: cats aren't scratching to sharpen their claws, but to leave scent marks on the "portals" to their territory. Wild cats do this on trees to mark out the limits of their range and to know when they're coming back to base. Domestic cats much the same - which is why they often have an apparently irresistible need to scratch at a point near their entry/exit points (near doors, windows, catflaps, etc.) It's often a bit of a compulsion-routine-habit - with an indoor /outdoor cat doing the same steps over and over again - enter home, wander to scratch spot, scratch, proceed to food/water dish, settle down for a snooze. It's like a sort of mild OCD ritual. So if a cat tree or scratcher is in the "wrong" place for them - even if it's already well christened with their smell - they just won't use it. Give Ziggy a chance to get it good & stinky and if he's not touched it at all, then try just parking it in different spots. (The right spot will probably be right in the way where you the human will trip on or bump into it constantly, btw.)
it's only been since early y/day morning but we're worried.
