Download building plans for these feral cat shelters: http://fivercats.com/

Take a tour of feral cat shelters made by my husband for our community cats. We fill the houses with straw to keep the cats warm all winter long. Straw has less moisture than hay, which keeps it from freezing in damp weather. You can also line the inside with styrofoam sheet insulation. Be sure to get your neighborhood cats spayed and neutered and provide them with regular food, water (in a heated bowl for winter), warm, dry shelter and vet care when needed. Please share this video and help keep feral cats warm this winter.
