Cat Scratching Post

I couldn't afford to pay the high prices that cat scratching towers cost so with the help of my wonderful boyfriend and my dad and his shed, tools and random collections of useful stuff plus an offcut of cheap carpet, we set to work on designing a good tower that our boys would love! It stands about five feet high and has been in constant use from day one!
I am aware that natural rope is better however my boys seem fine with this nylon and we haven't had any problems and I'm always checking it and them!
