Yesterday my human put up a cat tree for me. I have been climbing in the cupboard, so she thought she would get me my own climbing frame, something to do with 'getting more exercise' and 'practising somewhere other than the balcony'. I have her well-trained. She has been lifting me up to the house section in an attempt to encourage me to climb there myself. Not likely. Give it a week and she'll be lifting me on and off this thing on my command. Finally they have recognised my rightful place at the top.
