Is it safe to give cats Frontline Plus a week early for fleas?

Yes it is safe to reapply most topical flea preventatives every 2 weeks if needed. This should be fine and safe to do since you are 2 weeks out. However, if you are still seeing fleas after this correct dosing, it is best to consider switching to a more effective product such as Revolution. Best of luck with your cats moving forward and keeping the fleas away. Take care.

The active ingredients in Frontline Plus are rather safe, so I would not be worried about any toxic effects this long after you applied the previous dose. Considering the bathing likely did remove a fair amount of the previous solution and you are seeing fleas, it's safe to say that Maddie will need some extra protection. The manufacturer recommends not bathing until 48 hours after applying Frontline, but I always advise not to give a bath one week after applying topical medications like Frontline to be safe. To be extra safe, you can get a different product prescribed by a veterinarian. I hope that helps and all is well with Maddie.

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

You can use Frontline plus while they have the Seresto collar but this should not be necessary as Seresto is good for at least 6 months. So I would not recommend applying an additional flea and tick preventive.

Yes ypu can give Frontline plus. You need to part the hair between the shoulder blades and make sure you put the liquid on the skin. If you think that will be difficult you can cut the hair in this spot and then rub the liquid into the skin with the tip of the tube, or have someone holding your pet for you while you apply the flea medicine.

If the active ingredient is Nitenpyram (I am having trouble finding this product online but I believe this is the ingredient) then it is fine to give along with Frontline. If you are having a problem with fleas in your cat you may need a prescription product that works long term from your vet such as Comfortis in addition to treating your home, all other pets, and your yard.

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.
