What is the best flea collar for cats?
I’ve never been a fan of flea collars, but the Serresto collar, for both dogs and cats, is the best I’ve seen. It lasts for 8 months and has flea and tick repellent qualities. It needs to be worn snug to the skin (you should be able to slide 2 fingers between the collar and the pet) and once applied should not be removed. In general I prefer Bravecto or Nexgard or Simparica over the Serresto Collar, but for folks where there is a much worse tick issue than where I live this is a good choice. I hear these collars sell like hotcakes up north.
What is the name of the oral flea and tick preventative?
Nexgard was the first of the oral flea and tick preventatives that came on the market. Then later that year a sister drug came onto the market called Bravecto. And more recently another sister drug called Simparica came out by yet a different company. I’m happy to report that they all have good palatability.
How long does a Serresto collar last?
I’ve never been a fan of flea collars, but the Serresto collar (for both dogs and cats) is the best I’ve seen. It lasts for 8 months and has flea and tick repellent qualities. It needs to be snug to the skin so you can slide 2 fingers between the collar and the pet, and once applied should not be removed. It doesn’t have a “break away” piece should a cat get caught by the collar. I’ve seen cats come in with a Serresto collar and yet still have fleas. This is likely because most folks don’t wish to keep the collar on snugly.
Does Bravecto work for cats?
For cats who are difficult to catch (especially feral cats), this flea product is fantastic! Or, if other products have failed you in the past, there is no known flea resistance to this product. One of my vet nurses used to have to apply Advantage every 3 weeks to her outdoor cat, but has recently had great success with Bravecto. Unfortunately, Bravecto does nothing for heartworm prevention. I live in heartworm country. If a cat goes outside and is battling tough fleas, we may use Bravecto, but we will need to add in a heartworm preventative as well here in South Florida. Heartgard for cats is a good pairing with Bravecto.
Is Feline Revolution a good flea preventative?
Revolution and Advantage Multi have both been on the market for many years. They are both topical flea and heartworm preventatives. They are both great products for treating fleas and for heartworm prevention. They also do a good job killing hookworms and roundworms in cats. I want my feline patients who go outside here in South Florida to be on a monthly heartworm preventative as there is no treatment for heartworm in cats. Cats can get heart worm disease. One of my vet nurses recently pointed out to me that Feline Revolution leaves the cats’ fur sticky for less time than Feline Advantage Multi. They are different products with similar efficacy and safety. I like them both.
Is Advantage Multi good for dogs?
Advantage came out in the early 1990s. It has been a wonderful thing. There is minimal drug resistance and it remains a fantastic option for flea control. Again, I’m not a fan of topicals on dogs now that we have so many oral options. Advantage can be purchased over the counter at pet stores. There is a fancier option for Advantage called Advantage Multi that has Moxidectin for added heartworm protection and this is a prescription drug. Again, I prefer oral heartworm and flea preventatives for dogs. And, if I do have a dog with a food allergy and many of the orals have beef or pork, I tend to reach for Revolution as my topical medication of choice due to the aforementioned effectiveness for scabies. Nonetheless, Advantage Multi is a great product.
Is activyl good for puppies?
Activyl is a great drug. It is a topical that is approved for puppies 8 weeks of age and older. Activyl is a flea adulticide that has flea repellent qualities that are fantastic. It also kills the immature stages of fleas. If a pet is exquisitely sensitive to flea saliva, I may add Activyl into the treatment protocol.

Does Revolution cover intestinal parasites?
This is a weird one – it actually covers different parasites in dogs and cats! In dogs, it does NO intestinal parasites. Zilch. Is it all bad? No – there are good uses for it! Revolution is unique because it is a liquid that goes on the skin as opposed to an oral pill like the previous medications. Even though it does not prevent or treat any intestinal parasites, it does prevent/kill fleas, treat ear mites, and even treats sarcoptic mange! It protects against one species of tick, so I usually recommend other products for dogs needing tick protection.
Does Lufeneron prevent heartworm?
This is basically Interceptor (not Plus, just regular) with the addition of Lufeneron. So, yes, it prevents heartworm, roundworms, hookworms, and whipworms. The Lufeneron is a flea birth control. It basically stops flea eggs from hatching. No, it is not a flea killer! But, if your dog meets a flea, it might crawl around for a few days, but nothing more will become of it. You won’t get an infestation. For dogs who live in areas without a lot of fleas, but the owners don’t want to drop their guard totally, this is a great option.
