I don't think there's an answer for your problem. I don't agree w/ letting cats out - I've made that clear. I know that prospective cat owners that interview for rescues get turned down for wanting to let them outside or declawing them.Since you have no answer for cat owner's practicing common courtesy instead of entitled behavior, you try to change the subject.....
There are some people that will care for a group of feral cats by feeding them and giving them water and warmth during the winter. The ones that are truly doing good though are the ones that then capture them, and get them spayed/neutered.
