Have you trimmed his nails yet? Once a month trimming helps a LOT. My guys get twice monthly trims (especially Harry)

Also, watch how he scratches. Is it laying down? Vertical? Scrunched up? Stretched out? Get a post that will best match his scratching habits. Pouncer stretches out as long as he can get. A short little post wouldn't do him any good, so he has a loooong board to sacratch on. Abby scrunches up almost into a ball and scratches fast in one little spot, so she's happy on a small carpet scrap on the floor. Get the idea? I just watched how they naturally prefer to scratch and set up scratching areas just for them based upon their preferences. They don't scratch anything they aren't supposed to thanks to that (and their twice monthly nail clippings)
