The objects of the Society are the prevention and suppression of cruel and improper treatment of animals and amelioration of their condition generally throughout the city of Chennai.
The means employed for the attainment of those objects are:
1. The agency of paid Officers whose duty is to watch, warn or prosecute as needful all persons found guilty of inhumanity to animals
2. The provision of infirmary for the treatment of animals
3. The provision of refuge for animals incapacitated for work by reason of old age or otherwise

It does not restrict itself with prevention of cruelty alone but goes further. It takes intensive care of animals and pets. To take care of animals and birds the Animal Welfare Board of India was established in 1962. The prevention of Cruelty to Animals Act was enacted by the Parliament on 26-12-1960. The S.P.C.A Inspectors are entrusted with powers for prosecuting offenders under this Act.
