  1. Pay no attention to the ones suggesting using hay as an insulator. Hay gets wet quick and stays wet. The cats get cold and stay cold. Use straw. Also, no blankets for the same reason as no hay.

  2. Use straw rather than hay–repels bugs and stays dry. Don’t use blankets, they get wet from cat entering the shelter. Use lots of straw in the shelter that cats can nestle into for warmth.

  3. Many of these instructions talk about using HAY as insulation. Hat should NOT be used because it retains water. STRAW IS THE PROPER INSULATING MATERIAL TO USE. Cushions, fleece, fabric, blankets should also be avoided for the same reason.
