Hundreds of millions of free-roaming dogs and cats live in human communities worldwide, in conditions of significant welfare risk.
The welfare of street animals varies enormously by context. In some communities, dogs and cats are well-integrated and receive informal care from residents; in others, they face persecution, poisoning, and brutal culling campaigns. Trap-Neuter-Vaccinate-Return programs are now supported by WHO as the most effective and humane approach to managing free-roaming dog and cat populations.
