I think you are right with a vesectomy not being completely foolproof they would of gone to the option of Castration.
With a group of carefully bred (as carefully as they can) individuals inbreeding would not help them at all.
Milo and Moonlight are related to all the cubs born to Saffiya and Solomon so to pair them up with those individuals would not be happening.If they are having a break that could be a good idea they have plenty of individuals now and are using all the space they have.1 Enclosure is being used for the Old Lioness Jade so in a few years that would be empty leaving more room for breeding again perhaps.
