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.

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

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 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.
