Neither do I, but cat's are labeled as being a feral animal, so that's why people let them out to do or go wherever they want to.Unfortunately yes I have nothing against cats if they are kept indoors/taken care of and its by no means their faults for the damage they do when let outside, they are only following their instincts. I fear what they may do to my property and animals if I send their cats to a shelter though.
I also haven't seen any signs of their chickens in a few months so I'm assuming they either got bored of them and gave them away(hopefully to a better home) or they were killed by their owners ignorance.
