We first bought Sentry on July 14, 2010 instead of using our regular anti flea product Advantage. We were trying save a few dollars since currently money is a little tight right now. We have three wonderful cats that we love dearly, one of whom was poisoned and treated for toxicity after applying the Sentry Purrscriptions Flea treatment. The product was placed at approximately 9pm in the evening. The first application was applied to the first cat Daggett. He acted a little funny after. We thought perhaps this was from the product being a little cold as it is a liquid. We continued applying the product to the other two cats (Norbert and Booger) in our household. When all three cats had been treated, our first cat began to have an adverse reaction. He began to race around the house trying to shake the product off. He also ran to his cat box and had a bout of incontinence. The second cat was given the flea treatment and also ran around the house trying to get the product off of him. He began to squint his eyes and experience lacrimation. The third cat luckily had no immediate reaction to this product. The smell from this product also began stink up our apartment and smelled like bug spray.
The product was not on our animals for any longer than 5-10 minutes. I immediately called the 800 Emergency line listed on the back of the product to ask what I could use to wash this off of our pets. I spoke with a representative and gave him the box information. He explained some animals do have a reaction to the product. You can use Dawn dish soap since our product is oil based and this should help remove the product from your cat’s fur. Since skin irritation may occur so you can also apply some Vitamin E. The cats may be experiencing a tingling sensation and this sometimes can bother some animals. Our product is NON-TOXIC so your animals should be okay. I also told him of the lacrimation. He asked if the cats had licked the product. None of our cats licked the product as we were monitoring them. I told the representative that was wearing medical grade gloves to handle my cats and their product had not only seeped through the protective barrier but was also burning my hands. I reiterated to him this is not a tingling sensation, this is CHEMICAL BURNING happening; he again stated their product is non-toxic. He explained I should wash with the Dawn soap and apply Vitamin E as well. I was assigned a case number to report any additional adverse reactions. If a product is non-toxic, how does an adverse reaction occur?
We washed our cats and did our best to get this product off of them. This was no easy task as it is oil based, not to mention having to bath cats. Our cats seemed a little better after we bathed them, however two of our cats were now shaken after the experience, crouching on the floor and hiding.
After this incident I went online and did some researching only to be horrified at all of the other experiences pet owners have had. These experiences not only include cats and dogs but incidents caused by other Sentry products as well.
The next day on July 15, I began to notice clumps of fur around my apartment and immediately re-inspected my pets. All three were experiencing fur loss. I called and spoke to Sentry again and informed the representative that I wanted my case number updated to reflect an update to the already reported adverse effects. It was explained to me to gently brush the cats to stimulate fur growth and keep applying the vitamin E. Sentry Purrscription was had now caused my cats to lose their fur in the spot their product was applied. One cat (Norbert) was affected worse than the others. His fur was significantly shorter and he had loss the most fur out of the other two cats. He was also not acting appropriately. He was breathing fast; panting, hot to the touch; his gums and inner eyelids were pale and he was crouched on the floor in a corner. I looked up his symptoms online and included the Poisoning in my search. I found multiple online resources reflecting information on toxicity and this situation being a medical emergency. (Keep in mind their product is “NON-TOXIC”). I called my vet and they told me to bring Norbert in. The vet assessed him and asked if he had ingested the product. I explained we had monitored the cats and none of them ingested the product. I also relayed the additional behavior the cats displayed after use of this product. Norbert was treated with lactaided ringers and Atropine for absorption toxicity from Pyriproxyfen. This chemical is used as pesticide.
Pesticide exposure to humans is hazardous and can be fatal. The same applies to animals. I can’t believe that this product is considered safe to use on our beloved friends and is so readily available. This is marketing deception at its absolute best. Sentry is allowing us to unknowingly harm our pets with the full knowledge of how dangerous their own product is. I consider myself one of the lucky pet owners whose animals so far are going to be all right; however I do not know the long-term effects of this exposure to my three cats. This is unfair to not only our pets but to those of us who are being led to believe we are taking care of them. I can only imagine the anger and grief experienced by other pet parents who have not been so lucky.
I’m amazed that some of the first few web sites that come up while doing research on Sentry pet products happen to be the Consumer Affairs web site. This is just verifying that something is not right. Multiple people have and are documenting the same experiences. Obviously it isn’t the pet owners making the mistakes. Those of us who have been placed in these situations have suffered damages as a result of Sentry’s lack of action and concern for our pets. Why is Sentry allowed to get away with this? Why is nothing being done? Consumer Affairs, I thought you were on the public’s side regarding this type of victimization. Allowing Sergeants/Sentry to pick up our vet bills is just allowing them to continue their harmful practices.
Please warn other pet owners. Call your pet shops and let them know of your experience. Shame on you Sentry.

I litterally JUST put this stuff on my 2 cats and was ABSOLUTELY HORRIFIED! I bathed bothed of them immediately in Dawn Dish soap. They smell terrible and I had NO idea this stuff was so bad till after I put it on and THEN decided to read up on it. Shame on me for sure. All I can do is pray they make it through the night. I’m not one to get all worked up about things but I DO intend to RAISE HELL about this!

I recently put this on my cat. He is a one year old grey tabby. He began itching the site non-stop. I bathed him with dish soap. However, the next day I found clumps of his hair around the apartment and a small bald spot where the tick medicine was applied. He has continued to itch this area even after I bathed him, he now has a bigger bald spot and a red scratch mark from his scratching. I called the vet and she said to put neosporin on the spot. Did your cats hair grow back?

I recently put Sentry’s PurrScriptions Plus on my 2 year old cat since Pet Smart was out of Advantage. I rarely put chemicals on her, but she had a bad case of fleas and I thought one time wouldn’t hurt.
Now she’s in an animal hospital fighting for her little life.
The chemical burned a hole in her neck, then she had respiratory failure. What the???
More people need to speak out about this product. Their consumer affairs is doing nothing but damage control on those who report adverse reactions to the cheap poisons they put in their stuff.
This is a terrible experience.

My cat is an older cat, 14 years old, and recently developed a flea problem. This is the first time since he was a kitten that he’s had fleas and back then we used Advantage which cured the problem almost immediately.
Since he’s an older cat I was worried that Advantage might be too strong for him so I went to PetSupermarket where we have him groomed and buy his food and asked what the alternatives were that were safe for older cats. The clerk actually recommended Sentry PurrScriptions so I took her advice. Apparently they were pushing the product to get it to sell, not because they care about our animals.
I applied the product as directed and after about a day I noticed he wasn’t scratching anymore so I thought all was well. After 3 days I noticed him complaining a lot and no longer eating but the scratching started again. I inspected him and he still had fleas so I thought I’d give it some more time to work.
By that weekend he’d barely eaten anything, was extremely weak and wobbly and had even stopped drinking water.
If you care about your pet, DO NOT USE Sentry PurrScriptions Plus Flea Control. As far as I’m concerned, this product and PetSupermarket has murdered our pet.

I put this on my kitty now I’m terrified.
I washed his neck off. He seems to be doing okay, but I’m soo scared.

This medicine is a disaster. My 12 year old Siamese female, who hasn’t been sick ever, has had a severe toxic reaction to this flea shampoo. We have incurred around $400 in vet bills and after 3 days, she is still not eating. Banfield has given her antibiotics, fluids, blood tests, etc. and she is still not eating or drinking. This product should be removed from shelves before they bump off more loved pets!!!!!!

i had used this on both of my cats cus they had fleas and instantly they started to act funny. twitching and going nuts, it bothered me. so i looked up this product and saw that this was hurting my cats. so i washed it off them instantly with johnsons baby shampoo(i have long haired cats), it helped a little but they still went nuts. so i tried dawn dish soap. however after having washing and them being very very pissed. i notice one of my cats breathing funny and still going a little nuts. why is she opening her mouth and panting after i wash the stuff off? is she panicking or is it the product making her sick? i hope it will pass but i may have to take her to the vet. what could this be? has this happen to anyone else?

I used the flea and tick treartment on my 12 week old kitten and I also deflead my house and I have not seen a flea in 3 days I think it works just as good as frontline or advantage. I ask the lady at petsmart if this would be harmful to my kitten and she replied “no it is the same stuff you are mainly just paying for the name”

I just put this on my cat who is 22 years old……..after an hour…she starting itching & twitching….I immediately washed it off w/Dawn…………I wish I had read the reviews before buying this stuff. I intend to take it back to store tomorrow for my money back. I will now got to the vet & buy frontline which I know works……….I am soooo glad I was able to read this info & get that stuff off of her.

After using the kitten version, my Hannah (6 months) stopped eating (she never misses a meal). The next day, I found vomit, and immediately took her to the vet. She had to have two expensive shots, and was not completely back to normal for a week. I had previously received a free sample of Revolution, and since she did not have a reaction to it, I’m afraid to try anything else.

Thank you SOOOOO much for writing this up and letting us all know, My mothers cat who I loved and adored passed away awhile ago and she had given me all of the cat things she had because my husband and i have 2 cats. I was going to do the cats flea treatments and I had one thing of advantage but wanted to do both of our cats and she had given me Sentry Purrscriptions that she had originally bought for her cat. I treated our male tabby with the one thing of advantage that i had left that i personally had purchased and was about to treat our female tabby when i decided to look up information on sentry before applying it. Im sure glad i did look up info and greatful that you have posted this. Now im starting to wonder what killed my mothers cat, he was only 3 years old and we had to rush him to the vet because he stopped eating and drinking and was crying in pain. The vet told us that his kidneys had shut down and that we would have to put him down. Now i wonder if this product did that to him. Very glad i didnt put it on our cat! Thank you again soooooooo much!

First, I want to say sorry to all those who had a bad reaction to this medication. It’s horrible when something bad happens to your pet; you feel so helpless. That being said, I have done the research and my cats did fine with this stuff. They did try to get it off like many others have mentioned but mine do that with ANY topical treatment I have put on them. Also, the active ingredients are actually some of the same used by both frontline and advantage and if you read the packaging, Sentry contains smaller doses. Chances are your animal experienced a side effect of the ‘drug’ just like some people have with human medications. Also, I don’t want to be a jerk but how can you be surprised that the ingredients are pesticides? You are putting it on them to kill BUGS. I did not like how oily the product is or how some of the customer service reps appear to have treated many of you that had the problem. I use comfortis for my dog and I hope they make a cat version soon. Then we can all avoid this problem!

I own three cats, one of which, Lulu, was experiencing horrible itching and skin irritation. I had gone to the vet about it but they couldn’t find any fleas on her so they didn’t recommend flea medication. So I got her a medicated bath at Petsmart (its done by their grooming services), to see if that may resolve any of her itching problems. When she was STILL itching I looked through her fur and could see black bugs crawling all over (though they don’t resemble fleas or hop…) so I decided to dish out the cash for Revolution for all three of my cats. I felt so bad for her that meanwhile as I waited for my order of Revolution to be completed and shipped I wanted to do something short term. So I went to Petsmart and asked what they would recommend. They said Sentry Purrscriptions (the water based spray kind).
I noticed my cat Lulu foaming at the mouth after I sprayed it on her (she had tried licking it off) – then it occurred to me – how is this spray even safe if you spray it all over their body and they can lick it/ingest it? I called the vet, explained my predicament and she said that she had never heard of Sentry and thus couldn’t advise me though she said generally the ingredients in a tick/flea treatment are toxic if ingested.
Two days later I noticed vomit on the carpet in the morning, and then twice later that day I saw Lulu foaming at the mouth and panting and sticking her tongue in and out in a panic . Concerned I decided to wash the Sentry off of all three cats. I then went online to see what the product reviews were. And as EVERYBODY will find obviously stated, many people have had deaths of their beloved pets or terrible sickness from this product. That is ridiculous that Petsmart sells this, and that their employee recommended it. CLEARLY it is not safe for the animals and should not be on the market anywhere.
If something happens to Lulu (or Ace or Belle) for that matter there absolutely will be a lawsuit. Money is of no matter to me, I will raise a living hell if something happens to any of my cats.
DO NOT USE ANY SENTRY PRODUCT.

I put Sentry Purrscriptions Plus on both of my cats.Esmerelda is an 8yr old Siamese Fats was an 8 yr old Bengal.I put it on in the evening both cats seemed fine.I went to work the next morning at 7am when I returned home at 10pm Essy met me at the door demanding that I fill her feed dish but Fats wasn’t there which was strange because he is always ready to eat he was a very demanding vocal cat.I called him and he didn’t answer I looked in his favorite places but he wasn’t there at first i was afraid my husband had let him out Fats had never been outside in his life.I was getting ready to go out and look for him when I walked into the kitchen, there layed my beautiful cat dead on the floor.Fats was a very large very active healthy cat he had no health problems of any kind and he was dead.I know that the sentry killed him.I wish I had read about it before I used it.I had always used Frontline with no problem but a lot of people told me that the sentry was just as good and a lot cheaper.I feel like I murdered my loyal friend just to save a few dollars.I think this product should be removed form the market before it kills any more pets.

I JUST USED THIS PRODUCT ON TWO OF MY CATS TWO DAYS AGO. MY OTHER CAT I DIDN’T USE IT BECAUSE SHE IS REALLY SENSITIVE. THE ONES I USED IT ON ARE DOING FINE BUT I WOULDN’T HAVE USED IT IF I WOULD HAVE READ THIS FIRST. SO GLAD I DIDN’T USE IT ON MY GIRL BECAUSE SHE PROBABLY WOULD HAVE HAD A REACTION TO IT. THEY NEED TO BAN THIS PRODUCT. MY HEART GOES OUT TO ALL OF YOU WHO HAVE LOST YOUR BELOVED PETS DUE TO THIS PRODUCT.
