I'm not terribly good at keeping my grass short but have learned to use a lawnmower instead of the strimmer and now gave lovely short grass in both gardens. A couple of neighbours have cats who I used to regularly catch pooing on my grass but since I started keeping it shorter they seem to have disappeared. Except... I now find 'offerings' in the same places that used to be their favourite pooing spots, e.g. an empty egg shell, a bone, etc. It feels like some sort of kitty version of a horse's head in the bed, threatening retribution for ruining their nice grass!
Lighthearted, obviously, but it's weird.
