Over the counter Hartz and Sentry products do not work. I suggest you get prescription strength flea medications. You can easily get these medications from one of our VETCO clinics inside Petco stores. Here are the ones in your area: ( https://www.vetcoclinics.com/services-and-clinics/clinic-locations-and-schedules/?zip=77081 ) Take the cats with you. It is first come, first serve and there is no exam fee so just the cost of the products. The vet there can advise you when you can give the new product based on when you applied the other product. You also need to treat your house and yard (if you have one for fleas). I suggest these products: ( https://www.allivet.com/p-1389-knockout-es-area-treatment.aspx ) ( https://www.allivet.com/p-9065-vet-kem-yard-spray-32-oz.aspx?SearchTerm=yard%20spray+Auto ) Hope this helps. Best wishes.

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.

Yes, you can give Aries Capstar in addition to the topical Sentry medication. Be sure to continue applying topical flea prevention monthly in order to break the flea lifecycle. When he is due for the next dose of medication, I would recommend using a higher quality (both safer and more effective) flea preventative, such as Advantage, Revolution, or Bravecto. If you have any other dogs or cats in the house, be sure to treat all pets with good quality flea prevention. I hope this helps and that all goes well!

I presume that you're talking about Sentry Calming Collar which is also a pheromone based product. I have not had clients use that because I have not seen any studies about it. Feliway has done a wonderful job of testing their products to make sure that they work, so I would recommend using Feliway since it is a proven product. Good luck! I hope that was helpful and answered your question. Thanks for using Petco Pet Education Center, formerly Petcoach.

Yes, Sentry products are not recommended. If you need flea prevention you should get it from your vet. My recommendation would be to try and wash off that medication ASAP. Use Dawn dishsoap to wash the cats since it will cut through the oils in the skin. Be sure to rinse them thoroughly and dry them with towels (not hair dryers). If they start showing any other symptoms, especially neurologic symptoms, they need to get to a vet as an emergency. Hope this helps. Sorry this happened. Best wishes.
