Does a cat actually poop?
I think one should calmly call a spade a spade. It is plain and simply cat shit.
I would never build in a new development area. Exactly because of such nonsense!
They don’t function properly anymore because of such a pile.
Who am I actually supposed to hold accountable if a fox, a marten, a raccoon, or something else shits in my garden? Last spring I had a raccoon family in a tree on my property. What are you supposed to do with that? I have a shepherd dog with a good hunting instinct. There are simply no problems with that.
I would kindly but firmly inform the neighbor, if he is interested in a quiet and cooperative neighborhood, that he should please refrain from such antics in the future. If he wants further escalating trouble, he can certainly get it.
It is always important to make such matters clear and settle them from the beginning. Otherwise, the provocations will only increase and lead to unrest and dissatisfaction among you. Don’t engage in a petty war, it’s useless. Better to go on the attack than to give in.
