Dog Poop

Go right ahead. No one is stopping you. Maybe you can pitch this on Shark Tank. You'd very likely stink up the joint and be laughed out. But I'm biased against the show.

You might become the next Elon Musk.

I think for sanitary reasons it would be much better to use other baits which do not carry the same issues and would be equally (or more) effective.

If rats are eating all the dog poop, why kill the rats - seems like they are performing a public service.
