I love this site. I have indoor cats and am always looking for new entertainment for them. I passed a house that had just had a new bath delivered and asked if I could have the pallet casing. Then on trash nothing, a lady had advertised a tube from a roll of carpet, I ended up buying the MDF board and some fake grass (purely because I was impatient and wanted to get it ready as there Christmas present!) , but sourced some old trellis fencing, some old fabric and made a now very well used climbing wall which I am continuously adding bits too. I love a recycling project!
