One of the committee members and I went down to do another mediation today. The complaint was that the complainant thought the cat was defecating upstairs.
When we arrived, the friendly cat was sitting in the corridor and came up to play. We spoke to the lady who looks after her and she kept insisting her cat was not the one defecating. She also asked why the complainant did not come and just speak to her directly. She also said that cats should be allowed out, which we explained to her, was not true. At any rate, she says she'll keep the cat in from now on, so we hope that the cat will be left alone.
