No longer works for killing fleas on our cats.We have 4 cats, the first time we bought last year in the Spring, it seemed to work but had to reapply at 3 weeks instead of 4. The next time we purchased (September) didn’t work at all. Spoke with a friend last week and she had the same problem with her dog and cat from this product. This year we went with a different, slightly pricier brand. Can no longer recommend this one

First, I'd like to say that I'm really impressed by this product. It does an excellent job protecting my cat from multiple tick species, and it starts killing fleas in just 24 hours. I appreciate that it breaks the flea life cycle and kills fleas, eggs, and larvae. Not only does it work effectively, but it's also priced reasonably. Highly recommend for cat owners!

The fleas have evolved and this no longer works.

Absolutely ineffective

Cat still scratching.

Still had fleas days after use with no change. Vials are poorly made and not quality controlled with extra plastic floating in meds

Better to get flea treatment from your fur babies from the vet because this one doesn't work at all!

It doesn't work at all. Applied it on 3 different cats on the same day. They all still scratch like hell since the day applying it. Worthless!!!

After doing quite a bit of research, I decided to give this product a try. I must say, the ease of application is a huge advantage. No mess, no fuss! It's just a straightforward process. I am extremely pleased with my purchase.

Have 4 cats, did not work on any of them and the cats go outside for less then 1/2 hour a day supervised. They seem to have more fleas since I applied the medicine.
