I put Sergeant’s Silver flea and tick powder on my cat because I noticed a lot of scabs on his behind and neck and I found a few dead fleas on his cat bed. Although I didn’t see any directly on him, I thought that I would put just a little bit of this powder on his back and see how he reacted to it. BIG MISTAKE! A few hours later, I noticed him coughing and foaming at the mouth and acting lethargic. I immediately gave him a bath (he was out of it enough that I could actually give him a bath!). He’s been sleeping ever since, I have been checking on him every hour since and I’m worried out of my mind after actually Googling the product and reading all of the horrific things that the product has done to pets and their owners! I am praying that he recovers fully! TAKE THIS PRODUCT OFF OF THE MARKET!
