For sure now, Cecil and Jericho's pride is in a very dangerous situation.
Jericho alone wouldn't have been able to protect the pride's cubs from other males for long,but what could have been possible is he could have bought them some time for cubs to possibly be a little older and possibly increase their chances of survival!
Now, unfortunately, what everyone was dreading is just around the corner.
A dozen cubs left behind by Cecil and Jericho have less than 20% chance of survival.
Any other males that take over the pride will kill the cubs and by any chance, if the cubs escape that, they will not be able to survive on the run, it will be hard to get food or they could just get killed by other predators like hyenas and so forth.
What a sad story!
