Cat in Vet thanks to flea drops

I have used the Hartz flea drops before with no problems on my 15 year old cat. I applied it this past june 30 2016. Next day she was vomting blood. Took her to the vet. She is still there on IV’s, Vet giving her laser for the neurological damaged she suffered because of the poisoning. My heart is just broken because of this. Why is this product still on the market???

2 year old cat with severe chemical burn from collar.

My cat has a severe chemical burn from a hartz flea collar. Vet gave me a topical treatment. I am very worked up and heartbroken to read that so many people have lost their pets while this company continues to turn a profit. How has this gone on for so many years? I’m scared of losing my cat.
