Sorry about butting in here but on the Mr. Yuck Stucker and pets. I tought my cat to understand the sticer by spraying the sticer with a animal repellant called OUT before I stuck it to anything and just left them laying on the floor in various places. within a day if he say the stickers he avoided them with or without the spray on them. Its been 5 years since I did that and he still respects the stickers.
