Typical suburban yard problem - cat & fox poo around the garden, in the growing beds etc.
I've been wondering, what about grabbing a flame gun and giving the occasional poo a good in situ toast instead of picking up and messing around with it? Would it kill the potentially present parasites' eggs and make the poo safe to simply decompose under a bit of mulch and nurture the soil? Would it work and would there be any substantial drawbacks? It would probably also destroy some other organisms close to the soil surface, but that doesn't actually sound like too much of a problem.
I don't want to try and exclude or deter cats and foxes from the garden, don't fancy picking the stuff up and binning it and not leaving any bare ground exposed at any time at all is not always practical / doesn't always discourage everyone.
So I'm thinking there must be a way to turn this poo situation to a gardener's advantage and deal with it safely within the garden's ecosystem. Anyone with an appropriate expertise who could prove me right or wrong?

Many thanks!!
