Abstract
Abstract An anti-mating composition is provided for dogs and other domestic animals based on a gamma -n-alkyl- gamma -butyrolactone and/or a delta -n-alkyl- delta -valerolactone. The composition may also serve generally as a repellent for animals. A process is also provided for inhibiting dogs from mating, as well as other domestic animals, by applying to the area or to the animal a gamma -n-alkyl- gamma -butyrolactone and/or a delta n-alkyl- delta -valerolactone. A process for repelling generally such animals from areas to be protected is also provided, by applying the compound to such areas.
