The K&H Pet Cot House uses the same comfortable raised frame and cover as the K&H Original Pet Cot with mesh center. No tools are necessary and easy to assemble. Elastic straps keep the cover securely in place. Each side of the house has a window that can be unzipped and rolled open for additional airflow. It provides privacy and shade for pets. It's like giving your pet an enclosed porch of their very own! Can be used with or without the house cover. Easy to pack and carry for travel. For indoor and outdoor use. One year limited warranty.
