I gave my ragdoll one tablet for the 1st time ever last night after dinner as directed, ( as he has sensitive skin and cannot use spot on treatments or flea collar ) he was fine at 1st, hour later he stated acting crazy, shaking his head, scratching and grooming himself like mad, going in and out of the litter box, then sat in litter box scratching, head shaking for the next few hours ..By this time i come and read the reviews and thought oh hell this is not good. I asked advice on a special cat n kitten foster carer page and was told ju...Read more

After reading so many scary negatives on this product I was very skeptical, If I was'nt clutching at straws I probably would'nt have even tried this product in fear of the worst.
But, after trying several spot on treatments and outdoor sprays to control the environmental infestations I had no other options.
I used diomataceous Earth outside, revolution spot on, frontline spot on and sprays in excess of $10/ltr and bathed our 6 month old ragdoll at least once a week (easier to manually pull fleas off a long haired cat). Nothing was working unt...Read more

Within about 5 to 10 minutes after feeding my male cat a tablet he couldnt stop vomiting, sneezing, shaking his head, eyes watering hiding, tounge hanging out and rowing in pain. It really made us feel awful and now my cat who used to follow me every where and love me soo much, avoids me. Im heartbroken and Disgusted with this terrible product! My cat is within the perfect weight range and NEVER had a bad reaction to revolution or that other liquid capsule o...Read more

1-2 hours after giving the tablet my 13 year old female Tonkinese cat became restless, seeking access to outside. Then overthe next hour she lay prone on the tiled floor, then withdrew to a corner then became more restless and seemingly grooming a dozen places at once, her paws, her belly, her tail. Her belly was heaving with rapid breathing and her ears were red suggesting high stress. Then an awful groan and she vomited up a belly full of food and assuming the tablet as well. She withdrew again and sought a quiet area away from me. Shortly af...Read more

I had used these tablets twice before. I have three rescue cats from the same litter and they are all girls. Eight months in age. They have never suffered viruses or had health issues and I have had them since 7 weeks of age. I gave all three of them the tablet three weeks ago at 5.30pm. At 8pm one of them seemed quiet (she is usually very active). I checked on her and was concerned as I felt something was up. After going to get them all a treat I heard her scream from the bedroom and the banging of the wardrobe door. The noise was horrible...Read more

Comfortis was given to my 23 lb female beagle on 9/14/17 at 530am- they gave her the 20-40 lb pill rather than the 10-20lb pill which I think has a lot to do with the issues she's having.... a few hours later she had violent vomiting that lasted off and on for 24 hours/ coinciding with yellowish diarrhea. Next day the vomiting has stopped but her yellowish diarrhea has continued. She has been very lethargic and showing ataxia in her hind end. Today on 9/17 she wouldn't eat and continues to have diarrhea. Every hour throughout he last two ni...Read more

We gave this to our 11 and 12 year old dachshunds a couple of months ago. One of them basically vomited off and on for about two months. The other dog and our beagle did not seem to have any problems with it. We decided not to give to the female who had gotten sick. The fleas and ticks were definitely gone and it lasted longer than we expected. So, we dosed the male and the beagle again two days ago. Last night, my male dachshund, otherwise healthy and proper weight, began vomiting profusely everything he had eaten. It looked like a week's wort...Read more

It is not possible that veterinarians are not telling us the side effects of these drugs and they are getting away with murder. Report them to the board of veterinarians. Also, beware of Apoquel.Stay away from Apoquel Oclacitinib, it is a drug given to dogs for allergies on their paws, skin. It is poisonous drug, if you look it up on drugs.com it will give you thorough information about it. My doggie was assassinated by an unethical veterinarian that did not bother to tell me the lethal side effects, did not give me a print out of it. My dog d...Read more

Our eleven year indoor 9lb cat yogi, she was itching like crazy. We closely examined the cat's fur with magnifying glass saw nothing took her to the Vet he used a nit comb and found fleas. Vet gave us Comfortis. Since my husband is knowledgeable in chemicals he did not want to give her anything, but a flea bath . Finally decided to cut the pill in half so she took half of the pill. We began seeing few dead fleas within hours. In a few hours I noticed a really strong odor, she smelled like the Comfortis and fishy the smell was so stro...Read more
