Cat Barn- Green with added wheat straw. Designed for multiple cats to curl up and keep warm in a nice and cozy shelter. We just had 6 kittens in one and it will accommodate two adult cats if they share nicely. For more photos go to our facebook page Feline Furniture The doors, floors, ceiling and door flaps are all insulated with 1/2 thick insulation foam. This will give your cat a nice dark, warm, dry place to hide, sleep, and stay safe from predators. See the picture with the open door and you will see how thick it is.. This picture shows us installing the insulation and it is not completely insulated yet. Don't buy a cat house without an insulated ceiling as it is too cold. The Cat Barn comes assembled, just take it out of the box and affix the awnings by inserting the supplied nuts and bolts in the die cut holes. So easy anyone can assemble it. No tools required. hand tighten. Its waterproof because there are no exposed seams, lids or open doors. We include 8" awnings that hang over 7" and go all the way to the ground. This along with a waterproof door flap eliminates any water or snow from splashing back into the shelter. People don't like to sleep in houses with their front door open and either do the cats. So when considering a cat shelter choose one that that the wind and rain can't enter, but has two doors. During introduction of the Cat Barn to your kitty put in some of the cat nip we supply and keep both doors open. The doors affix to the awnings. Just raise door up and it will catch on the hook and loop material. Once kitty is using it or has gone inside a few times, lower the back door. Then when he is comfortable close the front door. We guarantee 100% Catisfaction. If your cat doesn't love it, we want it back for a full refund.
