By 2025, U.S. shelter overcrowding is projected to rise another 40% from 2020, even as the intake pressure stays high. In the most crowded systems, animals can outnumber available space by half or more, turning every additional surrender into a capacity crisis. This post pieces together the 2023 baselines and local breakdowns behind that trajectory, from Los Angeles to Houston and beyond.
