The present invention provides methods for selecting pet-appropriate products such as pest control products by enabling the contents of an animal product package to be distinguished from another animal product package. The methods comprise providing an animal product package, wherein the animal product package is shaped characteristically of the animal, and enabling the contents of the package to be distinguished based upon the characteristic shape. As a result, the methods of the present invention advantageously reduce consumer confusion and error when choosing products for their pets which may cause harm or death if intended for use on another species.
