Since both Sentry and Frontline use the same active ingredient (fipronil) it is unlikely that you will see better protection switching to the Frontline. You will need to choose a product with a different ingredient, like Advantage or Revolution or a Seresto collar. If you choose to use another topical, I would recommend bathing your kitty today to remove any remnants of the Sentry, and wait 3 days to apply the next topical. It is important to wait after bathing so that the natural body oils have time to coat the skin to ensure adequate absorption. You do not need to wait or bathe to use a Seresto collar.

Cats can be sensitive to flea medications. For that reason it is safest to wait 2 weeks between products even with different ingredients. Your vet can prescribe a cap star which is a pill that will last for a day that can help while you wait the remaining time

Thanks for using Boop by Petco! Frontline is indeed effective. However, it may take a few days to see effect. Hopefully, it does work for Shadow. However, if no effect is observed, consider checking in with your veterinarian as other options could be attempted like Bravecto for example and even Capstar which has more of an immediate effect. Best of luck!

Frontline will kill fleas within 24 hours and ticks within 48 hours. To be safe, you should also treat all your cats as well. A majority of a flea population lives off the pet, only hopping on to feed. A flea treatment and prevention program will include treatment of the pet and the environment. Use a preventative for at least 3 consecutive months, preferably year round.

I recommend using Frontline or any other product that contains the ingredient FIPRONIL. This kills lice and can be found as an ingredient in Frontline and other flea and tick preventative products. I hope this helps guide you in the right direction. Please let me know if you have any other questions or concerns.
