Hundreds of millions of unowned cats live in outdoor and feral communities worldwide, facing significant welfare challenges and creating complex management debates.
The welfare of community cats is deeply contested: TNR advocates argue managed colonies with caretakers have acceptable quality of life, while critics note predation, disease, and injury remain significant. Individual cats within well-managed colonies can have reasonably good welfare, but the scale of the global problem means millions suffer without care. Both colony management and reducing new cat populations through sterilization are essential.
