Overpopulation in domestic pets means that there are too many dogs and cats living in homes, shelters, and streets. This happens when too many animals are born and not enough caring homes are available to take them in. When there are too many pets living in one place, it creates a dangerous environment for the animals and the people living around them. It can also cause economic and environmental problems. Stray animals can cause damage to property, spread disease, and become dangerous to humans and other animals. To prevent overpopulation, people should have their pets spayed or neutered so that they don't have any more babies. People should also adopt from shelters and rescue organizations so that homeless animals can find loving homes.
