That's how it works.
Once attached around the neck, the collar will release active substances as soon as it comes into contact with the skin and fur of the dog and cat. The active substances are distributed via the skin fat layer from head to tail and continue to be transferred in low doses for up to 8 months.
Seresto vet. kills fleas and rejects ticks and sandflies before they suck blood. It protects against the transmission of certain (especially tick-borne) diseases.

Seresto vet. tolerates water, so the outdoor cat is protected regardless of weather, and the dog can jump a walk into the sea without the collar losing its effect.
The neckline has two safety mechanisms that release or break the collar if the dog or cat is stuck in a branch, for example.

Warnings and precautions: it is recommended to remove any ticks when the collar is applied, as these may not be killed within 48 hours. The prevention of new tick attacks begins within 2 days of application of the collar. Fleets are killed and fall off the host within 24-48 hours of attack and usually without sucking blood. Attacks of individual ticks after treatment cannot be excluded. For this reason, the transmission of infectious diseases via ticks cannot be completely excluded if conditions are unfavourable. Seasonal felling may lead to a transient minor reduction of efficacy due to loss of active substance bound in the coat. New distribution from the collar occurs immediately, so full effect will be restored without further treatment or change of the collar. The product is water resistant and works even if the animal becomes wet. However, the animal should not be exposed to excessive amounts of water for long periods of time or frequent washing with shampoos, as this may result in a reduction in the duration of action.

Imidacloprid and flumethrin shall be continuously released from the collar to the skin and fur as long as the collar is worn.
