Spraying quote from this site http://www.declawing.com/htmls/article.htm

Deprived of its front claws a cat may become insecure and distressed. I can assure you that if Kitty becomes emotionally distressed, you will too. Kitty's display of distress tends to take such forms as urinating on your favorite rug or spraying your antique armoir. Feeling defenseless without her claws, Kitty may become hostile to people (including you), and to other cats and become more apt to bite.
