Last night I bathed both of my cats and then applied hartz advanced flea & tick drops. I came across this sight a couple of hours later and quickly washed it off of them with dish detergent. Both of my cats are still healthy and happy, it’s been about 12 hours since I put the drops on them. If I hadn’t found this site they could have been the next victims, they are always cleaning one another and they could have licked that terrible stuff! I cannot believe i spent 30 dollars on that product. I wish petco would stop selling it, or give me my money back.
