I used Hartz flea med on my cat, will she be ok?

After I used it I saw online that it kills cats left and right. Think my cat will be ok?

As many cats as it does harm, it obviously doesn't harm all cats or it would be off the market. So hopefully your cat is one of the lucky ones. But don't tempt fate: don't use it again! And if you just put it on her, a bath might help. But if it's been a while it's probably too late to wash it off.

ah Thank you for some reassurance

Keep a close on your cat. Watch for any signs of illness and take him/her to the vet right away if you notice anything odd.

It almost killed my cat. He was very, very sick. Always get flea medication from your vet. Hope your kitty is ok!
