Neutering

Neutering is castration, the act of removing the sexual organs from an animal (usually dogs and cats). Females get spayed, and males get fixed. The operation is regarded by some as important and is said to allow pets to have longer and healthier lives. Neutering is done by vets.

Humane societies, animal shelters, and rescue groups urge pet owners to have their pets neutered. That prevents the births of unwanted litters, which lead to the increased number of unwanted animals. Some countries require all adopted cats and dogs to be sterilized before they go to their new homes.
