How To Build An Inexpensive Cat Shelter
– (PDF Download from Alley Cat Allies)
Alley Cat Allies recommends that feral cat colonies have proper protection from inclement weather. Following are detailed instructions they have provided in a PDF download that are needed to build a feral cat shelter. These building plans are recommended for use throughout the United States. For extremely harsh, cold, and wet climates, insulation (as described) is advised. Alley Cat Allies recommends using straw bedding to keep the shelter warm, and not hay. They recommend against using blankets, carpeting or any materials like towels that will hold moisture. They also suggest using hardwood shavings, but not softwood shavings due to toxicity (and not cedar and pine).
