I put Hartz flea drops on my cat Henry about 3 weeks ago. He didn’t seem to mind. Gradually he got more and more lethargic. Last week I noticed a mass in his abdomen. I took him to the vet who told me it could have been from the drops. I had no clue flea meds could cause such illness in pets. His temp was 104 and they’ve kept him ever since. His temp finally dropped and they were considering sending him home but this morning he had a seizure. Again the vet told me it was probably from the drops. I’ve been looking online and have discovered that Henry’s not the only Hartz victim. I cannot believe this dangerous stuff is on store shelves!!! I know I’m responsible but I assume that if something is openly and legally for sale to the public and used as it should be it’s not going to cause harm. I am outraged that Hartz still sells this stuff! I am so mad that my poor Henry is having to suffer and may not even survive because of my ignorance but moreso because of Hartz’s greed and disregard for pet safety.
