We guess this is the work of the gardener. He is the only one who has expressed strong dislike for the community cats and Mom has seen him throwing stones from our flat on the 11 storey and he told Mom off for feeding the cats. The last time he also used string and wire to tie the 2 stone covers together.
If Bush isn't that scared of him, we might have discovered his head in the noose. Mom remove it after I took some photos. Moments later, she saw Bush walking in that drain under the covers and we both lifted up the heavy cover for Bush to hop onto the surface more easily.
Bush kept hanging around the hole of the stone cover in case any strangers or gardener walked past and he could make a quick escape using the drain.
Poor Bush :(
