A boarding cave could be purchased like a normal cave, but would enable a player to board other members' lions/lionesses. It would be used ONLY for boarded lions, so you could not put your own lions in the boarding cave.

Boarding lions would (similarly to reverse breeding) be based on a real countdown in days, not the number of rollovers - so, if boarding was accepted on 01/01/2023 for 7 days, the lioness would always be returned 7 days later on the 8th January, even if the player didn't roll at all.

The boarding cave would enable you to board lionesses in your territory for another member, and could provide one or two boarding slots. Additional boarding slots could be purchased for GB similarly to submale slots, lioness slots, etc.

Once a player unlocked the boarding cave, they could set a rate for boarding another member's lions. Then, members could board their lions in these caves for a chosen duration and fee (accepted/rejected by the owner like a normal stud or breeding request).

Boarded lions are transferred into the boarding cave and can be fed, played with, hunted, patrolled, and bred like normal lionesses/lions, but they cannot be customized, kinged, retired, sold, or chased. The only difference is that the lion is automatically returned to the original owner once the boarding time is up. Kind of like a loan. If the lioness still has cubs at foot when she goes home, the cubs are transferred to the original owner.

If the lioness was starving or depressed during the boarding, she would return home and the boarding fee waived at 10% mood/80% hunger. ALTERNATIVELY, owners could have the option to feed their boarded lions as well as the boarder themselves.

Why would this help?
- This would enable players to train other people's cubs or lions without relying on a promise
- Players could freeze other players' lions in exchange for a fee
- This would enable players to reverse breed with studs other than their own (e.g., buy a heat, have the lioness on board, and then wait for the cubs to be born - lioness goes home and cubs once aged up stay behind)
- Players could control durations based on their unique needs
- Offers a backup solution for players who have no territory but don't want to get rid of lions
