If a consolidation of tigers were to occur in the TOTE with a few enclosures to allow breeding, it would awesome to create a similar situation to the idea for the Orangutan and Gibbon, by allowing an aerial bridge between enclosures, like the Jacksonville Zoo in florida has, where the tigers walk in an enclosed bridge above the path between enclosures.
This of course would need to be a situation where the tigers are not able to move into an enclosure where another tiger is still in residence, but is worth considering.
