You don't need the clones. You just need to be able to stay out of the animals reach. We are the only animals capable of running for days at a time. We're not the fastest, burn motion is very energy conservative.
You could hurry most prey to chase you run away from it and just keep doing it until the prey died of exhaustion. Of course you'd have to be in top physical condition which mean or any of my clones would be but the training will be part of the requirement.
I don't recall anyone quitting over it. The day manager was a sweetheart and cleaned it herself as much as she could. I didn't particularly love the work, but I cleaned it a few times so she didn't have to, some of the others did the same. No one was forced to clean it, someone either the manager did it or someone called tribute. In any case once all the visible and smell was gone, she'd go in an bleach the hell out of everything.
