That's so funny. I think the cats sense she resents them. The few ferals left around my house (they're not really feral anymore) meow a greeting when we walk by. Years ago, one even turned into a 'watch cat.' He used to sit on the front step. When my husband and I would take an evening walk, he'd come down to the edge of the sidewalk and wait for us to come back. One time, he followed us all the way around the block. Just once. He discovered the exercise was pretty boring and never followed us again :))
