    This is the only product that I am aware of that will protect my cat from heartworms. She only goes out with me, but previous to using Revolution I worried that she might be bitten by that one mosquito. by on 08/02/2008
  • Better Meds for dogs and cats
    I have found a better tolerance of the revolution products with both my dogs and cats. No irritation or the stomache upset. by on 08/01/2008
  • Revolution cured my kitten!!
    I have a kitten.He had fleas and ear mites{disgusting little bugs}The 1st time we took him to the vet,the vet discovered that my kitten had fleas.Since my kitten was to young to apply shampoo,powder,or any of that stuff, he told us to brush his fur,it did work but all the fleas did not come out.The 2nd time we took my kitten to the vet ,the vet saw my kitten was scratching his ears too much,he checked my kittens ears,took out some wax ,and then he said "1, he has ear mites"He told me to take a look,it was disgusting.Then he recommended us to use REVOLUTION and guess what,my kitten stopped scratching himself. by on 07/30/2008
  • Works great on my 4 lb. dog
    Our chihuahua is 4 pounds, and we use the puppy/kitten formula.Lola has never had any kind of symptoms or side effects. I will continue to use revolution for the rest of her life. We take Lola to the dog park all the time, and she never has had a single flea. Works wonderfully, and is so easy to keep up with.I definitely recommend this product. by on 07/30/2008
  • Wonderful service!!!!
    My vet just stopped carrying Revolution. So now we can order from and it is going to save a ton of time!!!! The order came in really quickly and was perfect! Order Revolution from PetCareRx!!!! by on 07/28/2008
  • I watched the fleas fall off of my kitty, Star
    I couldn't believe it ~ my daughter brought home a kitty from the flea market that was covered with fleas ~ Star didn't like to be 'picked' at, so when we made an appointment at the vet I told them I wanted the best they had. They put Revolution on him. That evening we literally watched the fleas falling off of him as he was playing on the porch. I am still amazed!! by on 07/23/2008
  • Stick with the Best....
    I have used this for several years on my cats.....we live in the country, where the cats are exposed to a variety of pests....the revolution works great!I just wish they would come out with some snake one of my cats keeps getting bitten..... by on 07/19/2008
  • Do you care about your Pet?
    I highly recommend "Revolution". I have been using it on my Pets for 5 years. It is easy to apply. The Fleas are gone. For me it is also important that it protects against Heart-worms. I had a Dog dying from that Illness. I treated him with Pills. After his death I found a lot of Pills under Furniture. With "Revolution" you can be sure your Pet receives the Medication. by on 07/14/2008
  • Great product, great price
    I have been using Revolution on my dachshund or the past 3 years and have no complaints about the medication whatsoever. In the past I had purchased Revolution from my Vet which was quite expensive. I searched extensively for a better price and found it at PetCareRx. by on 07/13/2008
  • I love this!
    I have 4 cats, 3 of which go outside regularly. Since starting to use Revolution, they are flea free for the whole month! I was having to flea comb them nightly just to keep the fleas under control (and in turn off my furniture, beds, carpets, etc). Within 12 hours of using this product, the cats were flea free (the only fleas on them were dead!) I will continue to use this product as long as I see this kind of result! by on 07/05/2008
  • Great!
    This is great for flea prevention as well as many other things all in 1 product. Love that I can use 1 product to prevent so many things. Easy to use and works great on my little chihuahua. by on 06/28/2008
  • Protects cats against heartworms
    I was unaware that cats could also develop heartworms until our calico, Smudge, was diagnosed heartworm positive. My daughter mentioned that she used a flea preventative topical medication that also protected against heartworms. My vet had never mentioned Revolution so I went online and have been ordering it from PetCare RX for all of our cats. I am so happy to have a found a product that protects against fleas, ticks, heartworms, etc. Thank you Revolution!! PS - Just wish I didn't have to go through my vet for a prescription - hope it will someday be available over the counter. by on 06/15/2008
    I have 3 dogs and have been using this product for 3 years now. I have never had any fleas, ticks or worms and my dogs are safe and happy. I push the product to the line with all the hiking and trail riding I take my dogs on. by on 06/13/2008
  • Easy and Effective
    My cat and I really enjoy using this product. It prevents so many problems and I only have to buy and apply this one medication. We've been using it for 6 months now and have had no fleas or other pests. It's so quick to apply to my cat's shoulder and she's never had a bad reaction or side effect from it. The medicine package comes with convenient stickers that I add to my calendar to remind me when it's time for Olive's Revolution. I recommend this product to all the pet parents I know. by on 06/12/2008
    My pup has had skin problems in the past and when we switched him to Revolution the problem almost instantly went away! Also, I love the fact that we don't have to buy a separate heartworm and flea medication. by on 06/07/2008
  • Great price and Product
    I get revolution for my two Yorkies because I think it is a great product. I get it hear because it's a great price. I get it at a 25.00 savings. by on 06/07/2008
  • A Must for your Pet
    I am very happy with the product. We have no Fleas in the House. I have no dislikes. by on 05/25/2008
  • Recommended Highly
    I have 2 rescued dogs that are 3 years old that were going to be put down. One is a Parson Jack Russell and one is a Rat Terrier. My Jack Russell has been on Revolution since we adopted her. This is the best product on the market for fleas, parasites etc. This product requires a prescription.My rat terrier is on Advantage until she gets a heart worm test done. then I will change her to Revolution also. by on 05/20/2008
  • Great Stuff
    My cats take no notice to the medication. They are both healthy and I have had no problems with fleas, eat mites and their last test proved worm-free. They are very happy and healthy. by on 05/19/2008
  • owned by Goober
    Product excellent-(would prefer to buy 3 doses at a time instead of 6). by on 05/12/2008
  • Best product I have found
    I like Revolution and have been using it for our four dogs for many years. It takes care of the heartworm, fleas, and ticks. Although our dogs are not outdoor dogs and are small dogs, their care is my ultimate concern. (They do spend some time out of doors and take walks in the park.) I have a Pom, Pom-a-Poo, mixed terrrier breed, and a Sheltie. I have never seen a flea nor have I seen a tick. Heartworm is not a huge concern in our area, but because I walk dogs in areas where other dogs have walked, I want them to be protected. For these reasons, I will continue to be a regular customer. by on 05/06/2008
  • careful
    does well for fleas but have 2 cats with ear mites and one cat whose hair started falling out by on 05/05/2008
  • Great for delicate breeds
    We have two Italian Greyhounds and now a third - for these dogs who have reactions to medication often, this product is the best. It keeps the fleas, worms, mange mites, and even earmites away. by on 05/05/2008
  • Pet Care RX
    My review is not so much for the product (which is great), but for Pet Care RX as a whole. I used to purchase my three dog's meds first from the vet for a very high cost and then from I've switched to Pet Care RX as the prices are much lower, shipping is more than reasonable, and you can earn discounts for your pets. THANK YOU, PET CARE RX, for helping pet owners get through difficult financial times while still providing quality care for their animals! by on 05/03/2008
  • Great stuff!
    We have 2 dogs in the 41 - 85 lb. range, and they have been on this medication for years. We have never had fleas, and the great part is that this is the only topical flea/tick medicine that also has the heartworm medication. by on 05/03/2008
  • Revolution is one stop shoping
    If your pet won't eat pills and giving multiple doses of meds is too much - try revolution! It is great! by on 04/22/2008
  • Revolution
    I ordered revolution because it is a great product. I have used it before, but not from Petcare. They were very attentive and helpful and their prices are very competitive. I recieved the cats revolution and now I am waiting for my dogs dosage, should be here Monday. I recommend this product to every pet owner. by on 04/19/2008
  • Not such a Revolution
    I used Revolution for four months and initially things were great. Then the fleas returned in greater numbers than ever. We've added the Program to the program and hopefully this will help. by on 04/15/2008
  • roundworm
    This product worked great and fast to clear up my cats roundworm problem. I highly recommend using this for a easy treatment option. by on 04/10/2008
  • Worth the Money!
    It may seem a little higher in price than some of the other items out there, but since it treats multiple issues, it's well worth the money. We've been using it on our two cats for the past 3 years and love this product. We'd definately recommend it to someone else! by on 04/07/2008
  • love it
    moved into a flea-infested apartment unfortunately for Mr. J, my cat. The vet said use the Revolution and I know that I'll never stop putting it on Mr. J as I haven't had any issues with any type of flear or other bug since. Plus, he had an ear problem (tested negative for the mites) since I got him at age 6 mo. (he's about 7 years old now) and his ears still have some wax, but he doesn't go crazy scratching them anymore. Yay! It's a fantastic product, just wish there were a discount, but it's worth every pen ny! by on 04/05/2008
  • Highly Recommended
    My dog has had ZERO fleas on her since using this product (it's been 11 months now). She hasn't even gotten any fleas when my daughter's flea-bag dog comes to visit. Seriously, I would HIGHLY recommend this product to anyone - especially if your dog is an inside dog. by on 03/02/2008
  • Absolutely Works!
    I have had Sadie since April 2006 and have never seen a flea! So without a doubt I don't have to worry about heartworm either. Now I also have Sassy since May 2007 and still not fleas. Never in a million years did I think I could have dogs without fleas! by on 01/06/2008
  • Best on the Market.
    This product really works, tried all others and not effective like Revolution.Great product and no side effects, used on small and large dogs. by on 12/16/2007
  • Helped my dogs!!
    My vet could not figure out what was wrong with my dogs. After spending $600 on allergy tests that did nothing, I went online and found out about scabies - Revolution did the trick! They are healthy and happy again and NO MORE ITCHING! by on 11/13/2007
  • Years of Success!
    Have used on my cats consistently for several years and have not had any fleas, mites, worms! Well worth the money and so convenient to use. by on 11/12/2007
  • 7 years and counting
    I own two goldens with lots of hair, not a flea or a tick in 7 years. Friends who using a competing product tell me they haven't had the success I've had using Revolution. I told them they should switch to Revolution! Plus it has the heartworm preventative too, so you don't have to buy two products. by on 11/09/2007
    Absolutely not a flea in sight. I used frontline before and it did get rid of fleas but it does not keep them off. Revolution appears to prevent fleas from even jumping on and with the combination of flea and heartworm prevention my dog is covered. I highly recommend this product. by on 11/08/2007
  • Works Well
    Good because you only have to give one thing one time per month by on 11/06/2007

  • Perfect! The product covers everything you worry about and the treatment is all rolled into one!
    I like the fact that everything is covered as far as what a dog can contract, you don't have to buy three different products to keep your ped safe just ONE Revolution! It's silly not too! by on 10/26/2007
  • terrific flea killer.
    I rate this product an A+. I have had the usual problem this year with fleas. After 2 days I noticed when I was combing the cats out and looking for fleas. I found alot of dead ones. the cats haven't been scratching and neither am I. by on 10/25/2007
  • Ridgeback/ Beagle mix abused, saved from kill center 2yrs old
    Revolution has cleared everything up except the scars. Best product used. by on 10/18/2007
  • The best product available...
    When compared to others like Heartgard and Frontline, there is no comparison. I've had issues with the other products, but never Revolution. In my opinion (and my vet's), it's one of the top products on the market. And i've been using it on my 95# American Bulldog for years. JD by on 10/17/2007
  • Revolution is the best!
    I've used Revolution for years for my dogs and would like to use it for my cat! by on 10/11/2007
  • A #1
    I have 5 rescued dogs & this is the only thing that works..why buy several products buy the one that does it all. Won't use anything else by on 10/01/2007
  • reliable product
    I first used this when I got a free one from the vet years ago. I put it on a local stray cat who's ears were all bloody and barely there. The next day the ear mites and fleas were gone. Just like that. That made me a believer! So now I use it on my cats as I have one that goes outside. It works within one day to kill the fleas, and I love the fact it removes the ear mites as well. by on 09/27/2007
  • Covers most normal pet afflictions
    For the cost this product offers the best protection against the problems caused by parasites found most in dogs by on 09/26/2007
  • Ferret owner
    I actually use the smallest dosage for my ferrets and I recently took in a severely flea infested ferret. I put the revolution on her that night after a bath and by morning all the fleas were dead, not a single one on her (and she had thousands before)! I haven't seen any side effects on any of my fuzzies and I've been using it almost a year now. by on 09/15/2007
  • It works.
    This is the best product on the Market. I know my Pets are protected from Insects. by on 09/14/2007

  • It Simply The Best
    I have been using this product for years and have never had a problem. Not a flea, tick or anything. This product does all it says it does and I recommend it to everyone. by on 07/11/2007
  • The Best
    Prevents heartworm, kills ear mites, kills fleas--it doesn't get any better than this. Never had an adverse effect. Unlike more popular products that don't work, this stuff works. by on 07/04/2007
  • Great Product
    This product has kept my dogs parasite free for years. They hate the smell when first applied but I apply at night and they have forgotten by morning. by on 06/25/2007
  • Ease of use, effectiveness
    We've tried every product out there for fleas/ticks, and Revolution is the only one we've found that actually works 100%. Never any pests, no ill effects, and only 1 application per month instead of 2 or more to cover all our bases. by on 06/23/2007
  • WOW! Works Great
    Great Pryenes was going bald from hot spot on tail and fir ant bites as well as fleas, Hair has grown back and the dog is flea & ant free for months & months! by on 06/22/2007
  • The only flea/tick topical that protects against heartworms in cats, TOO!
    Cats are independent beings, they don't wait at your feet for any kind of attention. so when you've got thier attention to treat them for fleas, it's nice to be able to cover so many parasites with one squeeze of a tube, and to only have to do it once a month. No pills to try to fool these intelligent cats with. It's the only one that helps protect cats from heart worm disease,hookworm and roundworm diseases, fleas, ticks and ear mites. It covers each of my cats different lifestyles, whether strictly an inside cat, strictly an outside cat, or a cat that goes in and out at will. I feel I'm doing the best I can by them when I use Revolution. I protect them from all I can, Revolution's got the rest. by on 06/22/2007

  • works good on fleas
    works good on fleas and I have not found ticks on them, but I do not know how often we come into contact with them. I love it for ear mites. Used it too when a neighbor dog clearly had mange. by on 05/12/2007

    I have tried everything on my highly allergic mixed pups (Jack Russell & Cardigan Corgi) the fleas destroy these poor guys, Nothing works as well as Revolution. NO parasites of any kind and no reactions! by on 05/07/2007
  • No more fleas , ticks , mites or any bugs whatever!
    This product is "THE BEST" from personal experience I have used it on my pets for many years and have had no problems with any itching, scratching from fleas,ticks,heartworm etc. I highly recomend it to any one with dogs or cats. I have a American Eskimo long hair dog, a Chinese Pug short hair dog, and a short hair cat. All do extremely well with this product. Buy it, this product works! by on 05/03/2007
  • Works GREAT!
    Within hours my cats have nothing but dead fleas on them. I highly recommend it! by on 04/26/2007
  • The Best Product
    I can't believe this only had 4 paws. Revolution is by far the best. It holds true that you get what you pay for. Max is a 90# bulldog and has been on Revolution for over 4 years. I've tried others, but nothing has as much benefit and strength as this. Hope this helps. Sincerely, JD by on 04/16/2007
  • This worked like miracle no harm to my cats what so ever

  • LOVE IT!!!!
    My dog gets hot spots from flea bites. Revolution is great because it won't wash off during bath time. I have used it for over 4 months and have not seen one flea on her. I also like the fact that she is protected agianed heartworm. I highly recommended this product. by on 03/09/2007
  • It Works!!!
    I have a six cat household and care for a large feral(sp?) cat colony. My domestics interact with the feral cats and ear mites had become a very big problem with my domestics. After one month of Revolution my homey felines do not chase their ears around the floor with extende rear claws. I know this was painful for them, as it was for me. We have no ear mites now with the first application. I hesitate to use chemicals but in this case nothing else has worked. by on 03/09/2007
