Cave Lion fashions a fantastic Billy Cat climbing shelf. It looks pretty easy to do too. Looks fun! “I made an Ikea hack of my own a few weeks ago and thought you’d like to share it too. The shelf is made from a 40cm wide Billy shelf and it cost only 15€ (the shelf was a bit damaged at the store but it suited our purpose fine) and 5€ for the carpet (so that it’s not slippery)
