Have a go at designing a rhino enclosure. Used the attached sheet to help. Also google images of rhino enclosures.
Can't wait to see what your design is like!!
The enclosure must have adequate shade, a mud wallow, outdoor enrichment items and preferably a pool. Like Sumatran rhinos, Indian rhinos are susceptible to foot and skin problems so moisture is a must. Lounging under water with just their noses sticking out is a common practice of these rhinos.
