Hmm.... I'dask a vet about it, if I were you....
But....I don't really trust anything you spray on the floor that doesn't wash all the way off... (Vaccuums don't get all of it out, I'm sure) :?
It should be safe, but also says to discontinue if a rash developes.:?
I've used plain ol' baking soda before to elimiate carpet odors. Use it the same way....just sprinkle it over the intended area and vac up after a bit.
