Comfortis Tablets

My cat started having seizures and eventually killed him at 2yrs old. I didn't realise until after and heard something about it and started researching and completing shocked how they can even sell this product.

I gave a small amount of one of the pills to my cat, which was well under the weight limit. By later that day he had stopped eating. We went to the vet and they thought it was simply constipation caused by dehydration from the fleas. Went home with an oral laxative. Later that week he was dead with signs of liver and kidney failure. Spinosad, the active ingredient (which is a pesticide) should not be ingested by humans or animals. It kills the fleas because it is poison. Do NOT give this to your animals you are essentially poisoning them.

Within hours my old cat was given 1/2 tablet, he was not able to move - experienced symptoms of ataxia. We took him to our vet and numerous tests were done but all came negative. He was put on steroids and initially improved but never fully recovered and died within a few months. Had I known what I have learnt since, I would have never given Comfortis to him of course. I would have not taken him to the vet either and instead I should have applied chemical detox drops about which I only found out when it was too late.

I have two animals, both received their treatment on the same day.
One had no issues the other began falling, unable to hold himself up, his back end seemed to have partial paralysis. He continues to have trouble walking, he shakes, his head "wobbles". He doesn't appear to be in pain but after thousands of dollars at the vet, x-rays, blood work, etc The only thing that changed was Comfortis.
I do not recommend this product.

This is a highly poisonous product, was given by the vet to use on both of my cats, one of which vomited immediately, the other was unable to breathe 3 hours later and passed away. Now one is left without his friend forever.

We’ve given our 11y/o cat Comfortis two times in years past. Last night we gave him a dose. He went from healthy, happy and normal to dead in 8 hours.

Gave Comfortis to my darling girl and within a few hours she passed away. Just wish I had read these reviews beforehand. I will regret this for the rest of my life. How can such a toxic product be in the market?

Makes cats sick. They vomit every time. Sometimes within an hour, sometimes later. But every time. Cats hate it. They do not chew it like a snack. Not worth high cost. Ineffective. Company is indifferent to concerns. Took a lot of information, but refuses to do anything. Thus, wasting my time as well.

Just three days ago, I gave my cat the second round of this medication, exactly a month to the date. 4 hours later she is contorting on the floor, unable to breath and died within minutes in the car on the way to the emergency vet. I am heartbroken and distraught. Our family has been torn apart by this 100% preventable tragedy. Please, trust the reviews and do not buy this product. Do not risk their lives. I will forever regret and hate myself for making her take something I thought was going to help but instead ended her life.

Gave to our cat last Friday and within 4 hours he was dead. Cat was playful had nothing wrong with him, and gave him comfortis and he was dead ! Not first time using this product. Had 3 cats die within 3 months of each other
