This funny decorative owl is also very effective! It stands guard and warns you when someone arrives: its eyes light up one by one or together as it emits its famous tu-whit tu-whoo (your choice) as soon as a person or animal passes in front of its presence detector. Decorative, fun and protective! Can be placed on the ground or fixed to the wall. Works with 4 AA batteries (not provided). Plastic. Dim. 20.5 x 17.5 x 4.5 cm.
