Unpleasant (but not harmful) to cat paws and bird feet, these cat & bird prickler pads keep unwanted guests out of vegetable gardens, potted plants, flower boxes and more. Simply place the durable polypropylene cat and bird deterrent pads on top of soil to protect any area cats use as litter boxes, birds land to peck or chew, and other critters come to dig around and destroy your landscape. The versatile pricklers can be easily cut with scissors to fit any space, and are also great for training cats to avoid furniture surfaces indoors. Set of 4 bird deterrents. Each, 19 1/4" L x 5 1/2" W x 1" D.
