I have two cats, Neko is a great boy he scratches both carpet and cardboard posts, cardboard being his favorite, he likes catnip on them. Willie on the other hand scratches couches and will not TOUCH a scratching post of rope, cardboard or carpet. He pretty much just likes couches. I don't care about the couches but my mom does and my dad does because my mom does. Catnip has no affect on Willie. Now I thought he would scratch the carpet one because he wouldn't scratch rope or cardboard one so I was begging to get it and said he'd scratch it and problems solved. Well he didn't and now my mom is mad at me for making them get it ($13 which I offered to buy, dad said he'd buy it). Is there any other types of scratching post I can make or try?
