Protects your cat from the infrared rays, and the included clip allows you to remove the gap between the Kotatsu Futon.
Unfold the house and place the mat on the bottom to use. Place the kotatsu (human) duvet fabric or cover on the edge of the house entrance with clips (3 locations) to prevent any gap. Prevents cats from entering the kotatsu and protects your eyes from infrared rays that come from heat sources. When using with kotatsu (for humans), please make sure that the house is at least 7.9 inches (20 cm) away from the heat source. Check it regularly to avoid it being too close to the source of heat
