Walkway scratch mat
Had same issue as previous poster. The walkway scratcher which is meant to connect from the bottom to the middle platform was too short (appears to have been stitched on the wrong way round) and couldn't be attached. Also the corresponding hole to secure the screw was too far back so not able to attach the 'ladder' walkway which was disappointing. No parts were labelled either so instructions were only part useful. Have purchased this before with no issues so seems I got a poorly made one time.
