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.

I applied sentry plus on my cats 2 days ago and I’m still seeing live fleas what do I do?

Answer by Chewy • Aug 09, 2018
It's recommended to also treat your home and yard while you're treating your cat to prevent reinfestation.

What's the difference between this product and the Sentry plus?

Answer by Chewy • Mar 23, 2019
The Sentry PurrScription Plus targets fleas,deer ticks, flea eggs and flea larvae while the Sentry PurrScription only targets fleas and deer ticks.

The box says "deer ticks". Does this work on other ticks as well?

I know this product has a lot of bad reviews but ive been using it for years on my cats and haven't had an issue. I like that it protects against mosquitoes too. It might just depend on the cat.

I have used this for 3 months. My cats are still scratching and showing flea dirt. I am combing and bathing until I can buy another product. I have given it the the best chance of working, but I can't do it anymore.

Usually I use this without a problem but this year it has not touched the fleas. And in a houseful of cats not helpful. Not sure if something changed but I am now having to order double flea treatments because this did not work at all. Disappointing.

I treated all my cats and it did kill the fleas the first day. Day 2 they are back with a vengeance. I did flea bomb as well. Now they have to suffer until I can treat with something else. I've been combing and tried baths but impossible.

NEVER USE THIS ON YOUR PETS!!!!

We had a horrible experience with this product. We applied a small amount on our full grown cat, and she began having violent seizures and foaming at the mouth

We had a horrible experience with this product. We applied a small amount on our full grown cat, and she began having violent seizures and foaming at the mouth. WE took her immediately to the emergency vet where she was intubated and given fluids over 72 hours. She recovered, but the poison control told us this happens all the time with this brand. It's taken me a while to write this review because I was traumatized that I DID THAT to my baby. It was actually the irresponsibility and greed of this company that hurt my cat, and they won't even answer my phone calls or emails. Again, do not use this on your baby!
