Upon going to the pet store to look for flea products, I discovered that Hartz flea drops were much cheaper than some other brands. Not being rich, I bought the Hartz brand and applied the treatment to my three cats, ages 10 yrs, 9 yrs and 6 months. Twelve hours later, my 10 yr old cat was shaking and twitching and continued to do so through the night. My 6 mo old developed thick, large scabs on his back, which are still peeling off, taking the hair with it.
Unfortunately, a little of this poison must have gotten onto our 2-wk old kitten, as she has seizures daily.
