Materials and fillings differ by product. Listings cite exteriors like fleece, polyester and soft fabric; fillings and sensory elements such as catnip (sometimes blended with silver vine), paper pulp, crinkle paper, coco coir, woven palm leaf, and ABS plastic components.
Most listed door-hanging toys are non-powered and state "No Battery Used." However, at least one interactive model requires a battery (often sold separately) to power motion or sound features.
Documented weights range from about 0.05 pounds up to 1.06 pounds. Overall lengths across listings run from roughly 7.95 inches to 36.0 inches, depending on the model.
Some door-hanging options include scratcher or post-style components with a scratchable paper pulp surface. These products are described as helping keep claws under control and redirecting scratching away from furniture.
