I had this same cat decal previously on my car, most likely from another company, which lasted 5 years before the tail became detached,and the main cat decal was fine except for looking faded,which is understandable after 5 years. This new one refuses to stick probably, despite applying it correctly. The tail is barely attached to the wiper,and the main cat decal is lifting around the edges,and ears are curling forward. I'm not pleased at all but assume I can't return it now! Perhaps you can mail another decal and I will have better luck with it?
