I think it’s reasonable to assume that Bailey is in excellent health and has at least another two or three years ahead of him (potentially more). It’s not uncommon for zoos to euthanise the remaining elderly lion of a pride on welfare grounds when it’s companion dies, with the added reasoning that its health is declining and it’ll probably require euthanasia in the near future regardless. Since this decision was NOT made for Bailey, this indicates the zoo believe he has several years to go imo.
From a welfare perspective, Bailey needs companionship. He’s elderly and he’s not genetically valuable, so a non breeding companion would be suitable. I’d suggest one or two young lionesses that can be transferred elsewhere to breed upon his death, which will allow Colchester to reevaluate its options (including switching to Asiatic lions or upgrading its facilities to continue with African lions).
