The Platform & Loft system provides your cat with the perfect perch to relax. In addition to the 12-inch high platform with two decks (front deck 21"W x 8"D, rear deck 21"W x 5.6"D), your cat will enjoy an additional loft deck, which measures 21"W x 32"D. The loft sits 36" above ground level and it is all supported by 3"x3" treated posts that will resist wind, rot, and warping. The loft will give your feline friend plenty of room to enjoy a new vantage point. Both the platform and loft come completely assembled. Attach legs to platform, set in the cedar cat house and attach the loft on top. House Size: 17"W x 17"D x 23 "H*Door Opening: 6" round InsulationThis house comes with insulation included! Our insulation is made in the USA and is a certified "green" product. It is called LOW E reflective insulation.  Most manufacturers of dog houses are spouting out R-Value numbers and frankly most of them don"t even know what an R Value is.  R-Value is the resistance to conductive heat flow.  In dog houses, conduction is only 3 to 7 % of heat loss due to the small size of the cavity.The biggest heat loss (during winter) and the largest heat gain (during summer) for dog houses is not a conductive factor but a radiation loss/gain through infrared radiation.  Rather than getting into a scientific, hard to understand dissertation, simply think of it like a thermos bottle.  It keeps cold things cold and hot things hot with a shallow reflective aluminum barrier.  That is precisely what CatsPlay LOW E reflective insulation does for a pet house.  You may refer to our website"s LOW E link.LOW E is a Class A, Class I fire rated insulation made of pure reflective aluminum on both sides with a layer of closed cell polyethylene in the middle. It is non toxic and does not become brittle, crack, flake, or collapse  with age.A light weight mahogany plywood liner protects the inner cavity insulation from pet damage, ensuring long term durability.Optional Porch & DeckGive your cat house more character while providing your cat with a great place to relax in the shade! A porch and deck system also provides a superior way to protect the doorway from the elements.Optional Raised FoundationThe raised foundation for the cat houses is made of full sized frame members (2" x 3"). The posts (3" x 3") and the frame members are lifetime pressure treated lumber for outdoor exposure and ground contact. The decking is western red cedar planking which really compliments the cedar cat houses.The raised foundation is large enough to accompany the cat house and still provide a front deck area. It can easily accommodate the cat house platform system which opens up another tier area for extra cat friends or food and water dishes.  Either way, the raised foundation is a beautiful addition to all CatsPlay cat houses.Optional Heated Cat MatA heated pet pad is absolutely the safest, most reliable and energy efficient method to provide your pet with a comfortable warm environment during the coldest of winters.  Depending on the pad size, the electricity needed to operate the pad is the same as one light bulb (15 to 80 watts).  We recommend that the heated pet pads not be more than half the floor size of the cat or dog house so that the pet can either get off completely or partially as he chooses.  The internal thermostat keeps the temperature at a desireable 102 degrees when in use.The Dog and Cat Pad - indoor or outdoor - a small 9x12 inch pad that beautifully fits in our 17" and 20" cat and dog house.  It is a hard ABS Plastic pad so as to resist claws and chewing.  The first 18 inches of the power cord are steel wrapped for added protection. The 9x12 pad comes with a soft weave pad cover that allows the warmth to easily radiate through to your cat. The pad cover is removable and washable.  When you purchase a heated pad with a dog or cat house, CatsPlay will prep the house for the electric cord with a bug and moisture resistant hole plug at no charge.Optional "Peek-a-Boo" Cat House Clean Out DoorWith over 25 years in the pet business, we have listened to our customers and now offer an access door.  The "Peek-a-boo" Cat House Clean Out door allows the ability to clean out debris and check on the welfare of your cats, without having to unscrew panels or remove roof sections. .
