The Prevention of Cruelty to Animals Act was established to prevent the infliction of unnecessary pain or suffering on animals and define cruelty. It established the Animal Welfare Board of India to promote animal welfare, prevent unnecessary pain/suffering, advise the government, and encourage shelters for animals. The act also governs experimentation on animals by establishing committees to oversee experiments and prohibit those causing unnecessary suffering. Offenses under the act, such as cruelty to animals or violating committee orders, are punishable by fines or imprisonment.
