Reminds me of a incident that happened several years ago when I lived in a neighborhood... One lady had 4 chickens, the only person on the street to have any (she was my next door neighbor) when she was home she let them roam the yard, my dogs never gave the chickens the time of day and respected the fence between our yards... One day she caught another neighbors cats red handed chasing down her chickens in the back yard... So she approached said neighbor about it only to be met with a curse filled rant about how his cat is 'entitled' to roam the neighborhood and he can't and won't stop it from doing so just because she has chickens... A week goes by and the neighbor with the chickens has to rush two of her own 'toy' dogs to the vet, one dies and the other barely pulls through... Vet diagnosis the cause as 'rat poison' and sure enough after that diagnosis she searches her back yard (and tells me to do the same since we are neighbors) and she finds several 'rat pellets' tossed around her chicken coop area... Coincidence? Or payment for trying to do the right thing?
Exactly these people who do this usually don't care what you think they have an attitude and if you approach them that is a likely response. That is why so many on the forum preach shoot, shovel, shut up.
