My neighbor’s cat had kittens over 3 months ago. They were unwanted and living under a porch, being fed scraps of human food. My family adopted one over a month ago. On June 28th another was found dead in the street. I decided to go ask for the others, despite not being able to keep them, to ensure they would find good, safe homes. They were so infested with fleas that we could not bring them into our home. I tried bathing them in dish soap, but that didn’t do any good. They seemed to be suffering so bad that I bought Hartz 2 in 1 Flea & Tick Cat Spray. The bottle says to not spray on cats under 12 weeks. The vet has told me that these cats are definitely over 12 weeks. I did not spray on the full dosage of around 26 sprays. I sprayed 10 or less on each. I then rubbed them off with towels to get any excess off. Then, despite them acting normal, something inside told me this stuff wasn’t good. At that time, I hadn’t heard anything about how bad Hartz is. Our family has always used flea collars and flea shampoo, so we trusted the company. I gave the kittens baths less than an hour after spraying them. I scrubbed them thoroughly, but that didn’t get all of it off. It appeared that one had diarrhea-like symptoms, but it was not bad and I thought it might be due to their change in diet. They acted perfectly normal. On July 1 my sister and I went out to take them for a walk. We took one out and he was slipping on the porch as he walked, as if walking on ice. His legs were falling out from under him. We took him on the grass and the same thing happened. I immediately knew it must have to do with the flea spray. I called the vet and was told I had to get them there asap or they would die, because “that stuff is like poison in a bottle.” We raced there. The cat with the symptoms could not walk very well at all, as if it was on some sort of drug or alcohol. They also believe it might have gone blind. The kittens are still at the vet now. That kitten is still having trouble walking. I am not sure if it has or will regain site. There will likely be long-term effects. I believe the only reason it looks like they are going to pull through is because we were able to get them to the vet before further, more severe symptoms developed. The vet told me that every over-the-counter flea/tick treatment is unsafe and should be banned! This means that HARTZ is not the only evil! Never buy over-the-counter flea products. On top of this, it usually does not kill the bugs. If you have a flea collar on any of your animals, take it off immediately. These products are also unsafe for humans and should not be in our homes.
