Black cat Halloween decorations are offered in several size categories: small tabletop accents (about 8.5 inches high), medium yard figures (roughly 18–27.5 inches), and very large pieces such as inflatables or arches that can exceed 100 inches in height or length.
Lighted black cat decorations use battery power (examples include C or AA cells) or plug into AC power; lighting is typically LED or incandescent mini bulbs.
Common materials include plastic, polyester or other fabrics, paper or paper pulp, wire or wire mesh, and mixed fabrics like chenille or faux fur for smaller decorations and costumes.
Battery-powered decorations use common cell types such as C or AA batteries — examples include items requiring three C cells or sets using multiple AA cells (one example lists 8 AA batteries). Some items note batteries are required but not included.
Some lighted items list UL certification for indoor or indoor/outdoor use; cord or lead lengths are sometimes specified (examples include 12-inch or 52-inch leads). Spare bulbs and fuses are occasionally provided.
