Frontline Combo Spot On Cat Flea Treatment

Frontline Combo for cats is a spot-on, clear, amber solution for the treatment and prevention of flea and tick infestations and for the control of biting lice.

It is supplied in packets of 3 or 6 single use pipettes.

Each pipette contains Fipronil and (S)-methoprene. Frontline Combo prevents the multiplication of fleas by inhibiting the fleas eggs from developing.

How to apply Frontline: Hold the pipette upright. Tap the narrow part of the pipette to ensure that the contents are within the main body of the pipette. Break the snap-off top along the scored line. Part the fur between the shoulder blades until the skin is visible. Place the tip of the pipette on the skin and squeeze gently to empty the contents onto the skin at two spots: one at the base of the skull and one 2-3cm further back. It is important to make sure the product is applied to an area where the cat cannot lick the product off.

Once applied, Frontline Combo will last up to 4 weeks. It is recommended to not bathe your cat within 2 days of applying Frontline. Do not use on sick or convalescent animals. Do not use in rabbits.

This is a prescription item and will be sent once a valid prescription is received.

    "Pet drugs online is a company I use regularly to buy my dog the low fat gastrointestinal kibble and wet food. My dog especially loves the kibble. I heat both the wet and dry food during the cold weather and often add a little poached chicken breast."
