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.
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 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 Boop by Petco.
Sully is adorable! Thanks for including a picture. I wish I could give you a simple answer to your question, but every animal is different and some require a combination of products. I would say that about 50% of the animals I try it with have a good response to Rescue Remedy, so that is often my first choice for cats (especially since it can just be added to the water). I have not used the other products, but both appear to have ingredients that could be used alone or in combination with Rescue Remedy. Don't forget that natural supplements are much more variable than medications and will not sedate, so they are sometimes not enough for a very anxious cat. I also recommend combining supplements with a Feliway Diffuser ( https://www.feliway.com ) or a Comfort Zone Diffuser ( https://www.comfortzone.com/ ) in your house. This is a calming pheromone that will work for a month. You could also consider calming music specifically for cats ( http://throughadogsear.com/tace/through-a-ca
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!
