Our house abuts a wilderness area that’s been home to a colony of feral cats that the neighborhood has cared for for years (including spaying and neutering, and finding homes for the amenable ones). A couple of months ago a new family moved in across the street, and just now they had Animal Control out to gather up the cats. These are not adoptable cats, else they’d all have been homed already.
They took out a hit on the cats, basically. Motherfuckers.
They can still hunt and provide safety to other cats which can reproduce. Trap and release is better than nothing for sure.
