Materials in the listings include plastic polymers (e.g., polypropylene and polyethylene), soft fabrics such as polyester and fleece, polyurethane foam padding, and canvas exteriors on some indoor beds.

Outdoor cottage-style shelters are built with weather-resistant features (slanted roofs for runoff and smooth, rinseable surfaces) and more robust openings. Indoor cottage beds focus on plush fleece interiors, softer materials, and removable cushions for comfort.

Common features include slanted, weather-resistant roofs for water runoff; open or large roof/opening access to ease cleaning; and large doors or windows that promote ventilation and airflow.

Outdoor shelters emphasize spacious interiors and large openings for entry and ventilation. Indoor cottage-shaped beds prioritize plush linings, removable cushioned pads, and enclosed 'snuggle' spaces for comfort.

Care instructions vary by item: many recommend spot or wipe cleaning, removable cushions should be hand-washed (cold water noted for some listings), and rugs are described as machine washable with mild detergent and to be hung to dry.

Listings frequently describe a "large opening." One shelter specifies a door size of 10.75" wide by 15.75" high.
