Yes, it is a problem with human waste as well. That's why the human waste that
is spread all over farms in many states is first spun to remove the heavy
metals. It's a natural part of humans, dogs, cats etc. waste and when it's
concetrated to one small area, (your garden) the heavy metals can and do build
up to toxic levels. Do a quick search and look at all the court case documents
where farmers are sueing because their fields are ruined.

I disagree that herbivore feces contains nearly the amount heavy metals that
carnivore feces contains. This is taught to first year ag and biology
students.

--"If heavy metals were a problem in your cat & dog feces, it would be from
something in the immediate environment, & their heavy metals would
possibly match those of all the people in --the same environment."
