In spite of having care centers run by enthusiasts, growing cities have led to growing demand for animal care. Rescued and abandoned animals only need forever loving homes..... Need for animal welfare is based on awareness that animals are sentient and constitute a major part of the ecosystem and that consideration should be given to their well-being especially when they are used for food, in animal testing or in any other way. Animal welfare centers are either relinquished by their owners or rescued from streets. These animals might have been victims of abuses, cruelty and starvation. That's why it is important to understand and realize that this is a problem, and we all have to work for their betterment.
