Pet shelters are facilities that provide temporary homes for animals, primarily dogs and cats, that have been abandoned, lost, or surrendered by their owners. These shelters aim to care for the animals by providing food, medical attention, and a safe environment until they can be adopted into permanent homes. Many pet shelters also focus on promoting responsible pet ownership and reducing overpopulation through spaying and neutering programs. They often rely on donations and volunteers to help with daily operations and to find loving families for the animals in their care.
