We’d used Hartz flea drops for a couple of months without problems. But this last month, after treating our 6-month-old kitten, we had problems. Apolo became lethargic and started experiencing muscle spasms. He would try to meow, but didn’t seem to have the strength to make any sound. I called the emergency animal hospital and as soon as they heard the words “Hartz flea drops” they asked us to bring him in. Apolo had to spend the night at the hospital to receive treatments, and is now healthy again. But it was a terrifying experience that no one should have to go through. I’ve been in touch with Hartz regarding the problem, but have received the same “canned” response as everyone else here. I sent the vet report and itemized bill as requested. So we’ll see what happens.
Four days after Apolo’s experience, we saw a special report on the news about Hartz. Until then we had no idea how far-reaching this problem truly is. Through the news report, we found this website. We’ve since emailed everyone we know asking them not to use Hartz products of any kind. We also emailed Petsmart and Petco and told them of our experience (that was where we had purchased the drops). Hopefully we can help save at least a few pets.
