We keep no secrets, so we’re letting some very big cats out of the bag, to wit: You can see some very big cats (plus splashy mammals) at Siegfried & Roy’s Secret Garden and Dolphin Habitat.

Created by the magic maestros, the garden/habitat is a haven for the rare, endangered animals to which the duo have devoted their lives and featured in performances. In the garden, witness the exotic beauty of the “Royal White Tigers of Nevada,” white lions of Timbavati, Bengal tigers, and a black panther, among others, in a lovingly maintained sanctuary.

Segueing to a splashier environment (with 2.5 million gallons of water), framed by palm trees and lush foliage, the habitat serves as both a dolphin playground and research facility to educate about these intelligent creatures. Although the dolphins don’t perform, visitors can delight in their natural friskiness in views from both above and below the water.

Remember, it’s a secret. So tell everyone you know.
