What a beautiful cat!! This woman, although she probably THINKS she's helping them, actually has turned them feral. Especially if they "run like hell" when you try to approach them. So I doubt very much you'd be able to get her into a carrier to have her spayed.

If you happened to trap her or her babies, and take them to the SPCA, they would put them down in a heartbeat because, unfortuntely they would be deemed "unadoptable", thanks to your neighbor.

It's sad. She's hurting them instead of helping them. Stupid, irresponsible pet owners!!!
