Sprayed my cats with the Hartz Ultraguard Spray. Washed my hands twice. Something told me to google Hartz products. As I was doing that, I noticed it was eating away at my acrylic nails! Quickly washed hands with Dawn, washed the cats too. 30 minutes later, I’m feeling dizzy and short of breath. Headed to the doctor now. Don’t use this product! Praying my small children aren’t affected!
