The Hibernation Cave allows you to store dragons within it. Dragons that are stored do not earn income for their habitats and cannot be fed. The Hibernation Cave can be bought in the market in the "Buildings" section. The build time for the Hibernation Cave is instantaneous.
The Hibernation Cave's max capacity is displayed for each individual upgrade.

Shrines: Dragons can be fed to level 10 and be stored in the Hibernation Cave. Once the shrine you are working on turns silver you can take each dragon out one by one and feed it to level 15 before selling/keeping it. This will help save dragoncash and treats while trying to obtain the gold shrines.
Breeding: Additionally, keeping second dragons in the Hibernation Cave will allow for breeding of multiples when new hard-to-breed dragons are introduced, so that you may try in the Epic Breeding Island, Epic Breeding Sanctuary, the Breeding Cave, and/or the Enchanted Breeding Cave to obtain and display eggs; and/or to breed/sell for dragoncash when needed.
