What others are saying about Cheristin for Cats Topical Flea Treatment

“Cheristin came highly recommended by an online cat community after I reached out for advise. My indoor cats had fleas for nearly 4 months. I tried Advantage ll for 2 months, back to back applications. After that didn’t work, I then switched to Revolution (which requires an RX). I later came to understand that the Florida fleas have built up a tolerance to it, and so that didn’t work either. Cheristin claims to have 1/2 the pesticide (much safer for pets) than other topical medications, so I was leery that it would work. After dosing all cats just once with the Cheristin and treating my entire apt. with Mycodex Plus Environmental Control (great stuff), the problem is FINALLY solved! “

“After using Frontline and Advantage for years, they seemed to lose their effectiveness. We saw fleas on our cats, would treat with these other products, and see no decrease in fleas. So I switched to Cheristin, and it seems to work much better. It didn’t work immediately, but after the 2nd treatment, both cats were flea free.”

“We have a cat that has had skin problems for years. Excessive grooming and scratching, hair loss, bumpy bare patches of skin, vomiting up his food, etc… It turns out he is allergic to fleas, one bite and his skin goes bananas! Being an indoor/outdoor cat we need something that really works. This stuff works. Absolutely no issues. Now he is fat, happy and fluffy!!”

What People Are Saying About Adventure Plus Triple Flea Protection:

“This worked well on most of my cats that were nine pounds or under. It did not work so well on my cat over 12 pounds.”

“It’s been a week now since I applied this to my cats and the results were amazing. Fleas started dropping dead off my cats within 30 minutes. One of my cats had a flea farm on him, it took a couple of days to get the fleas all out, but my kitties have been flea free so far! Advantage and Frontline never worked this well, my cats were infested 2 days after applying it, but the stuff works great, it’s been a week and still now fleas. I totally recommend this one.”

“I have 2 outdoor cats. I’ve been buying the Advantage for over 9 lb cats but decided to try this because of the lower cost. So far, it’s working just as well. The application isn’t as “fancy” but it’s just as easy to apply.”

What others are saying about TevraPet Actispot II Flea Prevention and Treatment for cats

“Long time Advantage II customer here, gave this a shot because it is more affordable. After a week on my cat I see no sign of fleas. I’ll update in 4 weeks if I see any resurgence.”

“We have used Advantage on our inside cats for years including 3 outside cats which are feral for the most part. This product is as good as Advantage and so much cheaper! We wanted to try the product for a full 30 days before we posted a review. Its works great on the inside and outside cats. Its nice to have a product that works as well as a name brand but for a lot less money.”

“I have not had a flea problem for many years. This year, one of my dog’s brought home some fleas from a class we attended. Well fleas like rabbits breed quickly, in no time the other dog’s and the house kitties all had them. I bought the Tevra Pet Actispot II and within 24 hours all 5 cats are flea free. Would buy this product again in a heartbeat.”

What others are saying about Vectra Green

“Six cats with fleas is not a happy life – I was literally sleeping outside because I was bit so much. Hundreds of dollars on exterminater, flea bombs, ineffective flea collars, laundromats, and vacuum cleaner bags later and I’m sold on Vectra. Wished we had known about this stuff earlier. Been 16 months since we started using and we are flea free.”

“This is the best flea medicine out there. My cat is 100 times healthier then what she was. She is very allergic to fleas. She can finally feel comfortable laying on her back and keep her hair. I really thought I would have to put her to sleep from how sickly she looked. This product saved my cat’s life and for that I am very thankful.”

“This product was recommended by a fall from the humane society. It was extremely simple to apply to our cats, especially when compared to the product purchased from our vet. It seemed a little more sticky but that is minor as long as it works. No adverse reactions from our cats.”

What others are saying about CrossBlock II Flea Preventative for Cats

“I’ve always been an Advantage user and it works. But after rescuing another kitten, we are up to 4 cats and one dog. The cats are strictly indoors but we have an escape artist and of course the dog has to go outside so we treat everyone to make sure they stay flea free. Used this in trying to cut cost with new addition and after two months still not a single flea in the middle of flea season! Definitely will buy again as you get the same protection at half the price!!”

“It worked day one on my older cat and by the next day only 3 or 4 fleas were left on him. Day three, he was completely flea free. I was worried it would make him sick like another brand I used did to him, but he was okay. I will use it again next year before he gets infested.”

“This product works for my two cats. I was using a different brand before, one that costed a lot of money from my local vet, but switched because of the cost. Not only does this product work just as well, it seems to work better! My cats don’t scratch or itch themselves as quickly as they used to. It also doesn’t have a sticky residue like the previous one I was using.”

What others are saying about PetArmor Plus

“I live in the hot southeast of Texas. Fleas are everywhere. I have indoor cats but have had two bouts of fleas. There are five cats. I have tried the expensive counterparts from the vet only to be told by the vet that sometimes they don’t work. Wow…really? So, I tried Pet Armor plus twice now and both times it was effective and did exactly what it said it would do within 24 hours. I am flea free again for the second time in two years. I will always use this product if I run into a problem with fleas.”

“This product is very easy to apply. I have six cats, and they all let me apply it very easily. They did seem to get an upset stomach the first couple of days after application, but other reviewers have stated that that may be a normal reaction to the medicine. Overall, this seems to have taken care of my flea problem and I will definitely use it at the end of 30 days just to make sure.”

“Brought a cute stray kitten into our home, covered in fleas (and ear mites). After about five days of combing out gobs of fleas every day, got this from Amazon, applied to back of neck, and next day and thereafter I could not find another live flea. Plan to use monthly during flea season.”
