DO NOT USE SERGEANTS SILVER OR GOLD FLEA DROPS FOR CATS OR DOGS! That is, not unless you want to leave it to chance whether your furbaby will survive or not…I put Sergeants Silver on all of my cats and NONE of them showed any signs of trouble, except my sweet and quite petite (tho she does weigh at least the recommended weight of 5 lbs.) precious kitty girl Chili. I put the top spot drops on her and approximately 3 hours later, she began violently vomiting. I realized it was the flea treatment, as I am a vet tech and was very aware of the trouble people had with the Sergeants Silver and Gold. Like I said, I had no problems with any of my other cats and had used it once before on all of them, except Chili. She was nursing at the time, and I definitely knew I wasn’t putting it on her then. Anyway, not having any reason from experience to not use it on her now that the nursing was done, I did put it on her today and not only did she begin the projectile vomiting, but even after I washed it off of her with Dawn, she began having violent tremors and horrible muscle spasms. Since then, I have administered Robaxin which the vet I work for gave me to calm her tremors and help her rest. I also noticed that her symptoms, before dosing of Robaxin, also included being “off balance” easily frightened and she is not that way normally. As well, she was unable to get comfortable no matter what I did for her. Her heart was racing and her breathing was very fast and irregular. Now, after the dosing, she is able to stop trembling as violently, and she has been eating and drinking and not vomiting anymore. However, she IS still shaking. Her heart rate and breathing are slowly returning to normal. I have her isolated and quiet, have provided her with a heating blanket, and fresh food and water. I think she may pull through, and so does the vet at this point. I am very lucky if she does and I need prayers for her please. Obviously, this is very disturbing to me and I know that many folks have lost pets from this product. Not to mention a very traumatic experience for my sweet Chili.. I will no longer continue to use this product and think that it should be recalled and or banned! If folks would be willing to sign, I would love to start a new petition on change.org to call for Hartz to pull this product and any others that may possibly have the same effects on animals. Seemingly, there is no possible way to tell what cat or dog will have an adverse reaction to this, so WHY is it still available???
