I have two cats: one named stuart (male) and one named misty (female). I also have a black lab/shepard mix named fluffy (also female) I had fluffy on HARTZ flea drops last year with no reprocutions (thankfully) and my dad bought a HARTZ 3 in 1 flea collar for cats that we were about to put on. I found an article with a picture on an image hosting site telling about a person who’s cats died because of HARTZ spray that his cats ingested when sprayed on the cats bed. It said to do a search of HARTZ KILLED MY CAT on google, this was the first result. We have since thrown the collar away and my cats are safe. I just want to thank you for all the work you’ve done to spread the word. because you’ve saved my cats lives.
