When pet animals share our living spaces, their needs and natural behaviors sometimes are at odds with the varying standards for household appearance, sanitation, and polite social life that Americans have established over time. How pet owners have resolved these issues provides insight into their changing ideas about the role of animals in their households and suggests how much, or how little, people may actually know about the biological behaviors and psychological needs of the creatures they care for. This essay examines one particular issue associated with the problem of sharing spaces: declawing pet cats as a common solution to avoid destructive scratching. This is a volatile issue and has generated much emotional debate.
