We used hartz flea drops on my cat after she got outside one day. I started to apply the drops and she ran off. Not knowing what was happening I chased her an finished applying the medicine. Within minutes she started dry heaving. Urinating and pooping uncontrollably. Barely moving. I told my husband to give her a bath an use blue dawn to get it off just incase. After her tub she still wasn’t moving and breathing funny. She ended up foaming out the nose and bleeding through the mouth. Died within a half hour of administration. Couldn’t even get to the vet in time. My heart is still broken.
