Left a residue - didn't work
The cinnamon smell was quite pungent, like Dentyne gum on steroids. If one sprayed too much you could taste the smell for at least an hour!  I used it indoors to keep the bad cat out of the dining room, which she had been using as a toilet. It also left a film on the floor while not sticky was definitely noticeable.  For the first couple of weeks the product did work.  But she got used to it and then began her bad habit once again. So not a good investment of my $30+.
