Question by arcticwolf71960: Are Hartz flea products dangerous to cats?
I used some Hartz flea spray on my cats, and they started crying and running around like maniacs. So I wiped off their necks with cool tap water, and stopped using the product. Later, I heard Hartz flea products are dangerous. Is this true?

Any over the counter flea product is truly crap. Stick to topical flea preventions like Revolution, Frontline, etc.
Hartz doesn’t work.. and pass on the flea collars. I’ve seen more cats harmed by them than done any good.
