Important Information

Fleas rise to the top of your pet's coat as they die, so consider it a triumph if you start seeing more fleas at first, after treating your pet. If you’re still seeing fleas after application, it may be because your pet has picked up new fleas from the environment, which may include other pets, surfaces and outdoor areas. It may take up to 30 days to break the entire flea life cycle. Additionally, you should also treat sources of new fleas (i.e., carpet, yard, etc.) to ensure complete flea control.

worked great until

This product work great the first month for my 3 cats. But the last time I applied this. One cat was fine, the other had fur missing and bloody scabbing at the application site. NEVER AGAIN, I refuse the use the remaining application on oldest cat. This my fault for wanting to save money, I’m going back to Advantage for babies.

Does not work

This stuff is total garbage. My cats had more fleas after I put it on them than before I used it! Do not waste your money

Economical AND Does the Job!

I switched brands for flea control, as I have 4 cats, and needed to find a lower priced alternative. It has done it's job well! All of them have done well with the new product. Fleas under control, and easy to apply. I am happy with this purchase.

One tube was nearly empty this time

I normally have good experiences with this flea control. Although there’s typically not a large amount of liquid in a tube, one of the 2 tubes I applied to my 2 cats was nearly empty this time. Maybe 2 drops were in it. That cat started scratching again within 1 week of application. Now I’m afraid to apply another dose so close to the last application. This stuff is too expensive to have one of three doses be a dud.

I use this on a feral colony

This works well on my outside cats . They are not scratching as much but the fleas do have to land to be killed . I use it every 8 weeks on them .
