There are a range of safe and effective solutions, from collars to topical or oral medications. Some products also provide year-round prevention against heartworms and intestinal parasites.


Frontline Plus

Frontline Plus is one of the most effective flea and worm treatments for cats, offering 30-day protection from pests.

Fipronil, an insecticide, disrupts the nervous system of parasites and kills them quickly. S-methoprene acts as an active ingredient to control hatching flea eggs and prevent them from developing into breeding adults.

Frontline Plus formula utilizes two ingredients in combination to create an effective flea and worm control solution that kills adult fleas within 12 hours, as well as chewing lice within 24 hours.

To apply, part your cat’s hair between the shoulder blades until you can see skin, then place the tip of the applicator directly on that area. Squeeze gently to evenly distribute all contents on one spot on your cat’s skin.


Advantage is a veterinarian-recommended flea and worm treatment that kills fleas by contact. It’s safe for cats, and you can apply it monthly to prevent infestations.

Advantage’s active ingredient, imidacloprid, works quickly to eliminate fleas by killing their eggs and larvae – effectively breaking the lifecycle of these pests.

This makes the product highly effective against re-infestations and helps guarantee your pet’s safety. It can be used on pets, stray cats and dogs in your home as well as wildlife like raccoons or opossums.

Advantage is highly effective and kills adult fleas within 12 hours of application. To maintain its effectiveness, it must be reapplied every month.


Bravecto is a topical flea and worm treatment for cats that kills adult fleas within 12 hours, prevents infestations, and shields your cat from re-infestation for up to 3 months.

Bravecto works by targeting the central nervous system of fleas, ticks and mites. It does this by disrupting the normal flow of charged chloride particles into and out of nerve cells.

Bravecto’s primary ingredient is fluralaner, an effective insecticide and acaricide that eliminates ticks, fleas, and mites that feed on your pet.

Ticks and fleas are destroyed by this treatment by attacking their central nervous systems, leading to hyperactivity that ultimately results in death.

Bravecto is unique among other drugs for treating fleas and ticks because it doesn’t need a prescription from your veterinarian. Plus, administering it is simple too–one dose lasts up to 12 weeks–and requires no special equipment or preparation.


Fleas are an annoying parasite that can be highly frustrating for both pet owners and their animals. Not only do they cause significant discomfort to dogs and cats by scratching, chewing, biting and restlessness, but fleas also carry diseases that are harmful to pets.

Comfortis is a chewable beef-flavored tablet that kills fleas within 30 minutes and prevents infestations for one month. It can be safely used on kittens 14 weeks and older as well as dogs and cats of all ages.


Comfortis contains the chemical spinosad in a beef-flavored tablet that disrupts the nervous system of fleas, killing them within 30 minutes and preventing reproduction. This is crucial since this kills fleas before they lay eggs and has an immediate effect.
