A feral cat house is a shelter made for stray cats to provide protection from the elements and from predators. Feral cat shelters are made from wood, sturdy plastic or Styrofoam and are insulated with straw or another material in which cats can burrow. They are raised several inches from the ground, weighted to prevent blowing away, and sometimes have awnings or door flaps for further protection from cold, wind and rain.

Its website offers instructions for building simple feral cat shelters using either Styrofoam or Rubbermaid plastic bins. It advises that strong insulation and minimal air space are important for keeping cats warm. The website provides shelter size and placement suggestions, tips for reducing dampness, insulation ideas, and door specifications.
