  • Works well
This works so great for Pet Rats. I have a pet rat that was suffering from mites. I was having such a hard time getting ride of it. Of corse ALWAYS consult your vet. He recommended to get this online, so I did. And it worked. He went from patchy fur and itchy skin, too itch free and full fur.

  • Very effective product , more effective than vet prescribed meds even!!! 10/10 recommend
had younger ferrets who got fleas due to my lovely cats who like to make a run for the outdoors the minute we open the door to go out😂 I was very skeptical of using ANY product on them to try to get rid of the fleas, eventually I caved and used dawn dish soap thinking the soap drying out the fur/ skin some would be better then fleas on them sucking their blood!😟 After dawn bath , killed most but some still kept reappearing , ordered this .. applied it and then deep cleaned the basement routinely until fleas were gone! If you’re looking for a product that is safe , and effective!! THIS!! I have used this brand strictly on my cats and dogs as well and anytime summertime hits and fleas come out, this brand knocks them to 💀 Don’t fall for the capstar pills or anything vets try to prescribe as anytime I’ve gotten those they NEVER work. I swear by advantage brand!! Save yourself the stress of trying multiple products and get this!🥰 ... show more

  • Keeps my babies flea free! Safe & Effective!
Love that it is made specifically for ferrets just like another review had stated. Was having a hard time finding a ferret flea treatment, being a mom of three carpet sharks!! My two newly adopted baby girls brought fleas into the home and we needed a more natural and effective treatment to rid of them. It seems like within 24 hours of applying the flea drops to my three ferrets they were all relieved of itching and I only spot a couple fleas that weren't moving and all of them seem to be dying off. I indeed did have to keep up with the flea treatment every 4 weeks or so to keep the fleas out of the house and in order. We also vacuumed and wash their bedding consistently throughout the weeks. Honestly I buy one package that comes with two treatments and I split it between the three babies that I have and it seems to be effective for all three for a full month. Very hard to see the amount in the little administer bottles but seems like it comes with enough to split between my three. Will continue to purchase and would certainly recommend for anyone looking for an effectively treatment for their lil noodles. :D Sidenote: After 3 months of continuous treatment there has been no adverse reactions or irritations for my two girls and boy! ... show more

  • Worked great for my bunny!
I adopted a bunny from a random on Facebook. Was unpleasantly surprised to find out he came with more than just his water bottle and cage. Yep, that's right. He had FLEAS. After researching, I found that Advantage kitten OR ferret would work. I chose to use ferret since they're also considered "small pets" like rabbits, and not feline/canine. I also saw a few reviews of people using this on their pet rats, which are rodents as well and even smaller than my rabbit, so I felt safer using this. When I tell you, this bunny couldn't go 5 mins without scratching pre-application. After using this product on him, within 4 hrs, he was barely scratching 1-2x an hour, and now, 3 days later, he's not scratching at all!! I also saw semi-dead fleas on the lining of his cage the next morning! He's a different bunny now!! I'll be giving him the second dose in a couple of weeks, just to be safe. But I feel comfortable saying that this product DEFINITELY killed most if not all of the adult fleas infesting my bunny. 5 stars! ... show more

  • work for a day or so
Put this on my ferrets.. the fleas left for maybe a week. Then I started to notice them back on the ferrets again. I know you need other managment when dealing with fleas which we are using i just thought it would work for a whole month not just a week. The price for this item and how long it actual works for its crazy high. ... show more
