Not keeping your pets off of other peoples' property is irresponsible
pet ownership. If you feel your cat needs to experience the outdoors
to be happy, then an outdoor enclosure is safest for your cat, best for
the local songbirds, and most respectful of your neighbors.
Sorry, to be clear, that's a generic "you", not directed at any one
person in particular

Even so, it is still presumptuous and rude, not to mention that it
advocates cruelty to animals.
