PetArmor Plus Flea and Tick Prevention for Cats is a topical treatment designed to protect cats from fleas, ticks, and lice. This product is waterproof, meaning it continues to work even if your cat gets wet. Each dose lasts for up to 30 days, and the package includes six doses for a total of six months of protection. The active ingredients, fipronil and (S)-methoprene, are the same as those used in the well-known Frontline Plus, ensuring a trusted, vet-quality formula that begins killing fleas within 24 hours of application.

Advantage II Large Cat Vet-Recommended Flea Treatment & Prevention is specifically designed for large cats over 9 lbs and at least 8 weeks old. This product stands out as an easy-to-apply monthly topical treatment that eliminates the need for hard-to-swallow pills and does not require a prescription. It's effective against adult fleas, flea larvae, and flea eggs, providing comprehensive protection.

The Seresto Cat Flea & Tick Collar offers a convenient and long-lasting way to protect your cat from fleas and ticks. It uses active ingredients imidacloprid and flumethrin, which work by killing and repelling pests on contact—meaning fleas don’t have to bite your cat to be eliminated. The collar provides up to 8 months of continuous protection, which is much longer than many other treatments that require monthly reapplication. It’s suitable for cats and kittens aged 10 weeks and older, making it a flexible choice for most households. Another plus is that it’s vet-recommended and allergen-free, adding confidence in its safety and effectiveness. The collar is unscented and designed to be hassle-free and non-greasy, so it won’t leave a residue or smell on your cat. Applying it is straightforward—simply adjust the collar snugly but comfortably around your cat’s neck, ensuring it’s not too tight or loose.
