Our carpet cat trees and condos provide more comfort to the kitties, but not all are made with the same quality carpet. The general rule is that you get as much as you pay for because the carpet differs in its density. Do not forget that carpeted cat furniture has one disadvantage: you will have to work harder while cleaning it. Also, if you teach your cat to scratch on a carpeted cat furniture, you are sending the wrong signal that it is not a problem if she/he scratch over your expensive home carpet. So, it would be better if every carpet cat playground had at least one sisal post.
