What do foxes not like?
Loud noises and strong smelling scents. Eg. Worn Clothes.
Direct light, from a torch or so.
If these foxes are actually humans who would like to think they're anthropomorphic foxes, or furries, humans may kill them, but not eat them. That would be cannibalism, for in fact these are nothing but sexually confused teenagers. If these foxes are in fact real foxes, a human could eat one of he felt like it, although it's not a common act.
