Cats only bury their poo if they are a subordinate in the area. If a cat thinks it is TC, then it will just place its stool in the most prominent position possible to mark its territory. In the past, this has frequently been on top of herbs in our kitchen garden which is quite revolting. Foxes help with this as they will take over as dominant in the area. This has certainly happened to us and though it sometimes means dealing with fox crap instead, this is generally less repulsive to deal with and just sited on the lawn typically. In any case, have no issue with tidying up after a wild animal - someone else’s pet is a different matter.
Foxes rule, literally. Just don’t feed them!
