I just wanted to say thankyou to everyone who posted a story on here. Last night I put the second treatment on my cat of the Hartz 2 in 1 drops, I didn’t really think too much about it, although I should have lisened to my vet when he said the Hartz is known to cause seizures in cats, but hes also the type of vet that wants to sell you products to make money. Anyways, I noticed my cat licking between his shoulder blades as if to get the medicine off of him. I kept thinking that can’t be good and went and googled it and ran across this website. After reading all the horror stories I washed off what I could and put a doggy shirt (lol) over it so he couldn’t lick. But thanks everyone if it weren’t for your stories and this website god only knows what my kitty could have gone threw!
