Porcupine is one of the animals protected under the Wildlife (Protection) Act, 1972. The Act categorizes species into different schedules, and porcupines are likely to be listed in one of these schedules, affording them legal protection against hunting, poaching, or other forms of exploitation. The protection is aimed at conserving biodiversity and ensuring the well-being of various wildlife species.

It's important to note that the specific categorization of animals can be subject to amendments, so it's advisable to refer to the latest version of the Wildlife (Protection) Act or consult relevant authorities for the most up-to-date information.
