let me know if you find that article. Years ago, a cat rescue org. told me that bleach is so safe you can actually drink it and be ok (small amt.). I know, that's just wierd!
Anyway, if the bleach is mixed with 1 part bleach and 2 parts water it's supposedly fine and kills bacteria. When I had a bad ringworm thing going on in my apt. years ago, I was advised by yet another rescue group to make the above solution and use it to wash the cats with a washrag squeezed out from the solution. I did that as well as used a garden pump with solution to spray baseboards, walls, the bed and furniture (they deliver a fine mist) Ring worm is SO hard to get rid of and Fulvicin sucks. There is a better remedy now that kills it so much faster. (Than the typical 8+ weeks). And the bleach helped control it and tresederm on the cat's ringworm areas helped too.
But anyway, if there are any dangers, us in MA need to know- bleach is used in all the shelters (one place I went to made us walk through a pan of bleach solution in a big pan they keep inside the doorway to prevent others from bringing in infectious diseases, conditions, etc.
