Great flea medication, works like any name brand.
Great very effective inexpensive flea treatment. I have 3 cats that do go outdoors through the doggy door into the back yard so I needed some flea meds that work but didn’t break the bank and this brand delivers. I have been using it for quite some time before i did my review just to make sure it held up to what I needed. It did. I have never once seen a flea on any of my fur babies. Great product for the value and easy to use. Zero irritation and it soaks right into their fur and doesn’t leak. The packaging is durable, you will need scissors to open the package.

Works Great
We get fleas in the late fall where I live instead of the summer and all our pets were bothered this year. We are on a very tight budget and wanted something inexpensive that hopefully worked. We treated 4 cats aged 3-16 with this. Tested them with a flea comb three days after applying, and there were no more fleas! I have also purchased Amazon’s dog formula that also worked great. No side effects. Could be easier to use like a tube like some brands instead of a hard square does not squeeze out quickly, but that is my only complaint. Smells strong but only for about 24 hours.

Didn’t work for mine
Effectiveness is highly questionable, gets them scratching and digging, but killing and repelling, hours and days later, is rather dubious. I was wrong in my original opinion, fleas were virtually eliminated by day ten.

Great price and it works within 24 hours
Great cat flea medicine that works well and costs a lot less than the expensive brand name flea meds. I used to use advantage and one other one that can get super expensive when you have 3 cats like I do. So overall I definitely recommend it.

Works great!
After only about 8 hours, the fleas were dropping off my cat. Either the fleas were dead already or clearly twitching out, about to die. I believe flea meds are designed to attack the flea’s nervous system, causing paralysis and death, and it definitely appears to be doing just that. Easy to apply, just be sure to put the drops between the shoulder blades where your cat can’t lick it off.

Fleas don’t go away
This did not work on my cat and ended up with an allergic reaction. Still had fleas a few days later.

absolute flea killer
Used yesterday on my indoor cat who had been scratching a lot and had fleas – I applied in the evening, and the next morning the bag she had slept on was entirely covered in dead/dying fleas. I counted 17 (!!) And she was no longer scratching! Super effective and great price.

Wasn’t successful
One of my cas had a reaction which was probably my fault because I didn’t keep my two cats away from each other but he was foaming out the mouth and scream crying for a few minutes then he was fine.This is not a full solution – my cats still have fleas it didn’t get rid of them completely – we’ve been using treatment for our furniture – threw away carpets- and it’s still just not getting the job done fully.
