Step-by-Step Directions for Use

1. Prepare Your Cat: Ensure your cat's fur and skin are completely dry. Do not apply on broken, irritated, or wet skin.

2. Open Pipette: Hold the 0.5 ml pipette upright facing away from your face and snap or peel off the tip along the scored neck.

3. Part the Fur: Part the fur at the base of the neck, between the shoulder blades (the one spot cats cannot turn around to lick) until the bare skin is clearly visible.

4. Apply Directly: Place the pipette tip directly onto the exposed skin and squeeze firmly several times until the entire 0.5 ml liquid is emptied onto a single skin spot.

5. Post-Application Protocol:

   • Allow the site to dry naturally (do not rub, massage, or towel-dry).

   • Keep multiple household cats separated for 2 hours to avoid social grooming at the wet site.

   • Bathing Restriction: Do not bathe your cat or allow exposure to water for 48 hours before or 48 hours after application to allow proper lipid distribution.

   • Re-application: Repeat once every 30 days for continuous year-round prevention.

Safety Warnings, Precautions & Storage

• Feline Specific: For veterinary topical use on cats only. NEVER apply dog spot-on formulations to cats.

• Age & Weight Restrictions: Do not use on kittens younger than 8 weeks of age or weighing under 0.68 kg.

• Sick & Debilitated Cats: Consult your veterinarian before treating sick, convalescent, or severely underweight cats.

• Licking & Salivation: If a cat accidentally licks the wet application site, temporary hypersalivation (drooling) and mild vomiting may occur due to the bitter taste of excipients. This typically resolves quickly.

• Storage: Store below 30°C in a dry place. Protect from heat, sparks, and direct sunlight. Keep the blister pack sealed until application. Keep out of reach of children and household pets.
