✦ Why we chose it

Advantage II is the gold standard OTC flea treatment — the 'kills on contact' mechanism means fleas die before they bite, preventing the allergic reactions that make flea infestations so miserable for cats.

Advantage II is the most trusted over-the-counter flea treatment for cats, killing fleas on contact — before they bite — using imidacloprid and pyriproxyfen. It breaks the flea life cycle by killing adults, larvae, and eggs, preventing reinfestation. Monthly topical application, no prescription required.

Pros

  • ✓Kills fleas on contact before they bite
  • ✓Breaks the full flea life cycle
  • ✓No prescription needed

Cons

  • ✗Flea-only (no heartworm or worm coverage)
  • ✗Some cats dislike topical application
