Preventative Topical Flea Treatment and Prevention for Large Cats (Over 9 Pounds), Kills Fleas Within 12 Hours, 6 Count

The fleas came back with a vengeance this spring/early summer. My Toothless (he looks like Toothless from a movie about dragons), has scratched himself so much that he had lost 1/2 of his fur and had boo boos all over. This came to my house in one day. THIS WORKS! Toofy's skin still has some healing to do but he does not have fleas on his body period. Less than 24 hours after applying the fleas were not on him. I am so glad I bought this. I love my fur baby and he already feels much better. No Rx needed. Toothless has not experienced skin irritation where the product was applied unlike some other products I have used in the past. Affordable, easy to apply and it has been a great step in my home's flea fight (fleas are notorious and it is always a fight!). Great product!

I have been using this flea treatment on three indoor/outdoor cats for flea reduction and have applied it twice now in 6 weeks. It works very fast. Within a day my cats flea issue went away. I can see at the beginning of week 4, the cats start to scratch a bit and by the end of the month, they are back to full scratch. BUT, everything I have ever used is like this. The product does have a slight greasiness to it but nothing like the real cheap stuff from the large box retailers. It has the same smell, but not as strong. The grease spot is small usually goes away in a day or two. Overall I am pleased and have put one delivery a month into my Subscribe and Save. Excellent value!!!

This was my first personal experience with any Amazon Basics branded product and I have been beyond satisfied, I've been legitimately surprised at how well this flea treatment has worked. Nearly every review of an Amazon Basics product I've seen or read has been overwhelminly positive so I had high hopes before it even arrived. There is essentially zero difference in the efficacy & duration of action between the expensive comparable name brands and this. The box says to compare it to the Advantage II equivalent, which I have experience with. While the ingredients and all seem identical and likely are identical, it genuinely seemed to me that not only did this brand work just as well and as fast as Advantage II, it seemed to last slightly longer (I doubt there was a noteable difference if there was a difference at all). Bottom line is that you are essentially getting the most respected, best performing, highest quality topical flea treatment for cats on the market for half the price. If you liked Advantage II & it worked well for you, I couldn't recommend the Amazon Basics equivalent more. It's like you're paying double the price to get the same actual product in an expensive brand's packaging. Most topical flea treatments that I've used in the past have been fairly easy to apply and this product was no different. In fact, because of how the application nozzle was shaped, this product was slightly easier to apply than most. The nozzle is designed in a way that makes it effortless to easily & quickly move thru the fur without snagging, allowing you to quickly apply it directly to the skin. Application is so quick and easy that it takes literal seconds and can be completed before your cat has a chance to realize something is going on. It doesn't take much time at all before it is very clearly working. In under an hour, fleas will quickly begin dropping dead. This product doesn't gradually eliminate fleas, it eradicates them with a vengeance and aggression. Once it begins working, a layer of dead fleas will be left behind any place your cat stays for more than a short moment. The efficacy is legitimately impressive. Surprisingly, for a product that works so strongly in such a short amount of time, I have noticed my cats experiencing exactly zero instances of negative issues such as irritated skin (even exactly where it was applied). The easy application process and the effective yet gentle medications used make for a product that does exactly what it claims to do without seeming to cause any physically or mental discomfort for cats. I have 4 cats all with varying fur types, lengths, thickness, etc. This product seems to work equally well and for just as long on all 4 so it appears that if applied correctly, the fur type doesn't have much, if any, impact on product performance.

I have three cats; all of them tolerated the medication well, but weirdly enough, one of my cats got an ear infection soon after giving them the medicine. I am not sure if it was related, but I feel like I needed to point that out. That was the only "different thing" he had happen to him (this treatment) before getting the infection. I am only rating it so high because my other 2 cats were fine.

I do not recommend the Amazon Basics Flea Treatment for large cats based on my experience. After applying the product exactly as directed, my cat began showing significant and alarming adverse reactions. More concerning, my cat developed tremors, twitching, and loss of coordination, which was extremely distressing and required close monitoring. Due to the severity of the reaction, I had to take my cat to the veterinarian. After examining the affected area, the vet shaved my cat’s back and discovered blisters consistent with chemical burns. These injuries are still in the process of healing, which has been difficult to manage and very upsetting. In addition to the physical symptoms, there were noticeable behavioral changes, including lethargy, reduced appetite, and sensitivity to touch. These reactions went far beyond mild irritation and raised serious concerns about the safety of this product. As a direct result of using this treatment, I incurred over $500 in veterinary bills. To make matters worse, when requesting a refund, the company charged a $4.45 refund processing fee, which was incredibly frustrating given the circumstances. Despite following all instructions, the product was also ineffective in eliminating or preventing fleas. The issue persisted days after application, making the risks completely unacceptable given the lack of results. After researching further, I found numerous reviews from other pet owners reporting similar experiences, including tremors, twitching, and neurological symptoms. The consistency of these reports is extremely concerning. Based on both my experience and the volume of similar feedback, I would strongly caution others against using this product. I highly recommend consulting a veterinarian and choosing a more trusted, reliable alternative.

Love the 3-month supply for the money. Used it multiple times on my cat, who unfortunately did have fleas needed to get them off before a grooming appointment. It worked in less than 3 days and the groomer said he had NO fleas or eggs. He didn’t seem to any side effects and did not scratch the area. It is more of a thicker formula so I recommend applying with an additional person.

Kills fleas but doesn't prevent new infestations. Treated my cats for fleas. Killed the fleas. Great. One cat got out and brought home more fleas 2 days after being treated with this. Learned my lesson tp stick with product that I know works.

I put it on the feral cat 🐈 while he was eating on the porch. I got up this morning and noticed the orange and white colors looked brighter. So in 24 hours he's gotten no new bites to scratch. He looks so good. I've noticed no side effects. I always make sure he has clean drinking water ever day. He purred at me and butted his head against my legs in my wheelchair. It works. I got the 6 month supply. And programed ALEXA to remind me when to reapply.
