I have been really confused as to why our indoor cats have had a severely bad case of fleas recently. We have one adult female and two 4 month old males. Yesterday I purchased Hartz products to try to combat the problem. I bought the drops, spray, and powder. Last night, I applied only the drops the back of their necks. Within an hour, all three cats became completely lifeless, shivering, and acting very strange. The kittens are normally so lively that we barely can keep up with them. One of the male cats was laying on the back of couch, and when I turned back to look at him he had massive amounts of drool dripping from his mouth. I instantly knew something was not right with that medication. I put them in the bath and bathed them with Dawn lavender dish soap immediately. After all of this, I looked online to see if anyone else experienced these problems after applying this poison and was shocked to see the horrible stories. I was absolutely beside myself and felt so guilty for not checking the reviews prior to this purchase. Through the night, the cats slept the entire time without getting up for anything. This morning the smaller male kitten seems to be more active but the bigger male has not been himself and being very still for the most part. My adult cat is now hiding somewhere in the house which is also unlike her. I will never use another Hartz product again. I don’t understand how in the world this company can continue to sell these products? There should be a massive lawsuit against them! Is there something that we can all do to get this poison off the shelves??
