Vectra for Cats

Vectra Flea Spot-On Treatment for Cats

Vectra Spot-On for Cats is a monthly topical flea treatment designed to provide fast and effective flea protection for cats and kittens. Formulated with dinotefuran and pyriproxyfen, this quick-drying, fragrance-free, and non-greasy spot-on treatment kills fleas on contact, meaning fleas do not need to bite your cat to die. Vectra helps control adult fleas, flea eggs, flea larvae, and flea pupae, supporting complete flea lifecycle control. Suitable for cats and kittens weighing 2–9 lbs and over 8 weeks of age, Vectra offers convenient monthly flea protection with an easy-to-use patented applicator.

How it helps

Vectra combines dinotefuran and pyriproxyfen to target fleas at multiple life stages. Dinotefuran rapidly kills adult fleas on contact, while pyriproxyfen helps prevent the development of flea eggs, larvae, and pupae. Together, these ingredients help reduce active infestations, prevent reinfestation, and support long-term flea control for cats and kittens.
