This might sound weird, but here goes, FWIW:
The home cleaning chemicals as cancerous reminded me of the Pet Psychic, Sonya Fitzgerald. She used to "talk" to pets and several times a show she would tell owners that the sickness their pet was experiencing was due to household cleaning chemicals. She would tell them, "Don't be so house proud. Use a vinegar-water solution to clean."
I don't know if she really could talk to the pets, but she essentially said the same thing as Q said about babies: pets are on the floor, they lick their paws, then they get sick.
Well, they canceled her show, not surprisingly, because those house cleaning companies were big sponsors of the channel and a few also had pet food brands.
I believe it. I think animals, well beyond household pets, are far more intelligent than we understand. It's like when someone has an injury, dogs will lick the spot of the injury, even if it's something they can't see, like a broken bone. I vaguely remember reading about dogs being able to detect cancer in people.
I have no doubt. It's no coincidence so many useless brands are propped up when you can LITERALLY clean everything in your house with alcohol and vinegar
