My kitten's ZoGuard isn't working. Can I use Cheristin now?

According to the package instructions for Cheristin, it can only be given once a month, so you will have to wait until a month has passed before you can give her another full dose. Cats are exquisitely sensitive to flea medications, so it's very important to not overdose them with the medication. It's also important to disinfect the environment when a cat has fleas. Wash her bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Next time you need to put a dose of Cheristin on your cat, I'd have a friend help hold her so you can get the full dose on.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. Sorry both your kittens have ear mites! You have to wait at least two weeks after you applied the cheristin before it's safe to give them Revolution. I hope this helps!

If you want an effective product please use one of newer ones like Cheristin. I don't think you will get any better results with Advantage. It is recommended to wait a minimum of 3 weeks between product applications. https://worldtails.securevetsource.com/itemView/view/198944_HomeDelivery.pml?productId=115569 While you wait you can get Capstar and give him that every couple days if need be. One pill lasts 24 hours but will kill everything on him. https://www.petco.com/shop/en/petcostore/product/capstar-flea-tablets-for-cats-2-25-lbs You also need to treat the house or the fleas will keep getting on him. I recommend Knockout Spray ES: https://www.chewy.com/virbac-knockout-es-area-treatment/dp/53856

To be sure that you have done everything that can be done to prevent infestation of your other pet, I would recommend using a flea fogger from Lowe's or Home Depot to kill all the fleas that can hide in the cracks of your sofa and carpet. You will need ot evacuate all the pets from the home during the treatmnet, as instructed ont he canister. I wuld also recommend the next treatment of flea prevenation to be a higher quality flea preventative than Sentry. Sentry is a low quality flea preventative unfortunately. I only recommend the following for quality flea preventatives: 1) Revolution 2) Cheristin 3) Advantage 4) Comfortis I hope that you get rid of these fleas for good and protetct your other cat from getting them. YOu can also give your older cat a Capstar right before doing the flea fogger to really guarantee that she/he is flea free. Capstart can be used concurrently with any flea preventative b/c it is a flea ridder and not a preventative. Please let know if this answer was helpful to you and your cats! Thank you for your feedback and have a wonderful rest of your weekend. Take care!

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.

It's fine to go ahead and start the bravecto. I would also recommend being aware that it's possible fleas are in the environment (outside or in your house) and treatment may be required there to clear up the issue. And make sure you're treating all the animals in the house, not just the ones you see fleas on. Good luck with this frustrating issue!!

I'm sorry to hear about your issue with Cheyletiella. They are a bothersome parasite to deal with! Apply Revolution every 2 weeks for 3 treatments (use appropriate dose for your kittens' weight). You can use Frontline Plus as well if you feel you aren't getting the results you wanted at the dosage of Revolution stated above. Fontline Plus can be applied every 2 weeks at the correct dose based off body weight for this problem. You should also use a lime silver dip or topical flea product to clean the kittens. Diluted bleach 1 part bleach:9 parts water sprayed on all surfaces and allows to sit for 10 minutes before wiping clean should help. All bedding and toys should be washed in hot water or thrown away. Good luck and thank you for contacting me today!
