    My pet dog had all the symptoms one by one down the row and the Vet missed it all. I am so angry. How could she have missed this. She said the symptoms were of posion. My dog died.

    And the pet food company still denies it. I have called today and the same BS answer. Yet they knew of Itchmo saying the food that was tested was false because it had been open and may have been tampered.

    Funny, how they right away knew of Itchmo. I also told him about the story being in the newspaper about the Acetaminophen. Said he didn’t know about any acetaminophen.

    12 weeks and still grieving….

    My heart goes out to you, Ruth. I’m so sorry about the loss of your dog. I hope it brings some small sense of comfort to know there are many people out here who care and are working to make sure it never happens again.

    Hi Ruth,
    What food were you feeding?

  4. Ruth says:

    IAMs mini chunks.

    Come on guys - let us know what you were feeding if your babies had these symptoms… facts only. No speculation…

  6. Ruth says:

    Excuse me KitKat, what exactly do you mean by no speculation? I have posted in several blogs all over Itchmo with which pet food my dog ate. I may have overlooked in stating it but I’m not hiding it. It was just overwhelming that I went to and found the symptoms in order that my pet had and how fast she went down. And now reading how some results are finding Acetaminophen…

    These are the facts as I know it and my own opinion.

    Another good paper on Acetaminophen and cats, especially the part on diet.

    ” One final note is that research has shown a higher incidence of acetaminophen-induced methemoglobinemia in cats fed a diet high in propylene glycol than in those fed diets low in propylene glycol. Wet cat food contains 7% to 13% propylene glycol….. ”

    7 -13 % propylene glycol, sounds so nutritious. My cars cooling system prefers a 50% solution.

    Call 4 Action: Lab Test Finds Potentially Lethal Drug In Pet Food
    WTAE-TV-4 Pittsburgh June 5, 2007

    “The generic version of Tylenol, acetaminophen, for humans can relieve a headache and lower a fever, but for pets, even a small dose can be fatal.

    “Even the healthiest of pets might be no match for what’s in the tiny white pills.

    “”My first reaction is, ‘My gosh, who did this? Who put this in?’” said Dr. Mike Hutchinson of Animal General in Cranberry. “Was this a disgruntled employee or was this something that got by the test?”

    “Traces of acetaminophen were detected in dog food that was tested by a Texas lab called Exper-Tox.

    “The lab would not name the type of food contaminated or the company that distributes it but said the company is not among the 150 others involved in the pet food recalls over the past three months.

    “”What happens in cats is it goes to the red blood cells and binds up their ability to carry oxygen, so they basically suffocate,” said Hutchinson.

    “Hutchinson said those symptoms could come out of nowhere, even for a healthy pet.

    “The lab said it made the discovery two to three weeks ago.

    “The Food and Drug Administration officials would say only that they are aware of the information and are looking into it.”

    Propylene glycol in wet food??? yikes, I defifnitely don’t want to feed my cat that! it’s not on the label, but I suppose that isn’t anything new. I knew it was in the semi-moist food, but canned food? I switched to canned because of all the recommendations that it’s healthier for cats’urinary tracts among other things. This is really disturbing–i wonder if they were talking about canned wet food. Of course there’s that issue of diethylene glycol being substituted for glycerine, wonder of it’s also substituted for P glycol. Wonder if I email Canidae will they be honest with me about it.

    I just found this on, guess what, the FDA website. Makes me feel a little better since it is the semi-moist food that HAD it, not the canned (whew):

    “If scientific data are presented that show a health risk to animals of an ingredient or additive, CVM can act to prohibit or modify its use in pet food. For example, propylene glycol was used as a humectant in soft-moist pet foods, which helps retain water and gives these products their unique texture and taste. It was affirmed Generally Recognized As Safe (GRAS) for use in human and animal food before the advent of soft-moist foods. It was known for some time that propylene glycol caused Heinz Body formation in the red blood cells of cats (small clumps of proteins seen in the cells when viewed under the microscope), but it could not be shown to cause overt anemia or other clinical effects. However, recent reports in the veterinary literature of scientifically sound studies have shown that propylene glycol reduces the red blood cell survival time, renders red blood cells more susceptible to oxidative damage, and has other adverse effects in cats consuming the substance at levels found in soft-moist food. In light of this new data, CVM amended the regulations to expressly prohibit the use of propylene glycol in cat foods.”

    If anyone is still on this posting thread… sorry Ruth I did not express myself correctly. I didn’t mean to imply that there was any speculation - I only meant that I know we’re being watched and I just thought I would warn against anyone speculating. Sorry about that!
