Harts One Spot flea treatment killed my cat.  It caused acute liver failure and it happend quickly.  I had called the company and was told that it contained no pesticide, just give your cat a bath, I’m sorry she’s having a reaction.  They took my personal information and told me that if I could get a refund if I sent the reciept and the leftover product.  Why would I save a receipt, I didn’t know this was going to happen!  The refund was the least of my worries.  By the time I got her to the vet she was almost gone.  I was told the best thing to do was end her suffering.  A couple of days later the Harts Company called me back to see how my cat was doing.  I told them she had to be put to sleep because of liver failure.  The lady said that it had to have been going on for a long time.  I told her she was healthy before using the product and hung up.  I was furious!!  I’ve warned all my friends & family.  I wonder how many other beloved family pets have to die this way before something is done?

  1. Dear acoots0004,
    I am deeply sorry to hear about your cat, but want you to know that Hartz Ultra Guard One Spot does not contain anything that can cause liver failure or other internal damage.
    The sole active ingredient in Hartz Ultra Guard One Spot is S-methoprene, an IGR (Insect Growth Regulator), which is effective in controlling young, pre-adult fleas only by impacting arthropod metamorphosis. This effect is unique to insects and other arthropod pests and has no impact on mammals. Additionally, the active ingredient is 100% non-systemic and does not pass into a mammal’s bloodstream.
    The safety of S-methoprene has been well documented since 1975, when it was first registered; it is the same IGR that is used in the vet brand, Frontline. S-methoprene is even used by state and federal insect control programs to control mosquitoes in drinking water systems for humans. The use of IGR’s, such as S-methoprene, is actually recommended by both the ASPCA and Humane Society of America.
    If you have any other further questions about how the product works, please don’t hesitate to contact me directly at [email protected] or our in-house vet, Dr. Melinda at [email protected].
    Dr. Marta Draper, VP of R&D, Hartz
