What is a better type of scratch post?

I purchase a scratching tree several years ago. It is covered in carpet and extends from floor to ceiling. Two cats have used it over the past eight years and the only maintenance is to hammer back the staples. My cats love to run up at full speed. Maybe your cat needs one similar to this one. I have also seen cat condiminiums. There are many sold online, but I don't know who carries them in Austrailia. Check your retail stores and your vet. He may know.
