One of our cats has fleas (both do obviously, but one has more than the other) and we’re trying to figure out what to do since we used Sentry Purrscriptions Plus on them, and it hasn’t been effective. We don’t want to combine medications and make th
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.

My cat is 10. Has diabetes and asthma.i used sentry flea drops. Once last month and now this month.he is scratching and pulling his fur out in wads. What can I do for him. He's going crazy!
Hello, thank you for using Boop by Petco. He is probably having a reaction to the Sentry. This is not the best product and I strongly recommend you stay away from using it. This product is known to have a high rate of reactions. If you are looking for an over the counter product I would use [Advantage II](https://www.petco.com/shop/en/petcostore/product/advantage-ii-once-a-month-cat-and-kitten-topical-flea-treatment-over-9-lbs) but honestly, when a cat has other underlying health issues it is best to consult with your vet as to what the best product would be to use for him. At this point in time, the best thing to do is to bathe him in Dawn dish soap in an attempt to remove any residue from the Sentry and then wait two weeks before applying a different product. Hope this helps. Best wishes.

I place Sentry Plus flea medication on my cats last Wednesday. The medicine does not seem to be working. Can I safely use Frontline now or do I need to wait one month to apply it?
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.

My cat has fleas so I went to the pet store and bought Sentry topical flea and tick medicine for her then came home and applied it as directed. I didn't notice until after I applied it that she has a small open wound so I went online to find out if i
Thank you for contacting Boop by Petco with your question about Samantha. Sentry is actually a pretty good product, it's one that I recommend, and I would not worry about reviews online. That is anecdotal evidence not scientific evidence. She should be ok. I hope this helps!

I put sentry purrscription plus containing etofenprox and pyriproxyfen on my cat yesterday. Can I also give him capstar? He has fleas
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!
