Indications for use

Seresto for Cats:

  • Repels and kills ticks for 8 months including:

    • Deer ticks (vector of Lyme disease and anaplasmosis), American dog ticks (vector of Rocky Mountain spotted fever, cytauxzoonosis and ehrlichiosis), Brown dog ticks (vector of ehrlichiosis, anaplasmosis, babesiosis, and Rocky Mountain spotted fever), and Lone Star ticks (vector of cytauxzoonosis and ehrlichiosis).
  • Prevents tick infestations within 48 hours after application.

  • Quickly kills fleas on cats within 24 hours and continues to prevent infestations for 8 months.

  • Kills fleas that may vector bartonellosis (Bartonella henselae), tapeworm infections (Dipylidium caninum), feline infectious anemia (Mycoplasma spp.), and rickettsiosis (Rickettsia felis).

  • Re-infesting fleas are killed within 2 hours with protection against further flea infestation lasting 8 months.

  • Kills and repels fleas before they lay eggs.

  • Aids in the control of flea larvae in the cat’s surroundings following contact with a Seresto-treated cat.

Administration and dosage

  • One collar per animal to be fastened around the neck.

  • Remove collar from protective bag directly before use. Unroll collar and make sure that there are no remnants from the plastic connectors inside the collar.

  • Insert end of the collar through the buckle.

  • Adjust the collar around the animal’s neck without tightening it too tight or leaving it too loose. As a guide, it should be possible to only insert 2 fingers comfortably between the collar and the neck.

  • Pull excess collar through the loop(s). Collar length of greater than 1 inch (2 cm) beyond the loop(s) should be cut off unless it is on a growing kitten, where some additional length may be needed for adjustment as the animal grows.

  • After application of the collar, three reflector clips may be fixed permanently to the collar to increase the animal’s visibility in the dark.

  • Take the clips out of the bag. The clips should be evenly distributed on the non-overlapping part of the collar. The clips are correctly applied when a clicking sound is heard. For safety reasons once the reflectors are fixed to the collar the clasp closes permanently and cannot be re-opened.

  • The collar should be worn continuously for the 8 month protection period. Check periodically and adjust fit if necessary, especially when kittens are rapidly growing.

  • This collar is designed with a release mechanism. In the unlikely event of a cat being trapped, the cat’s own strength is sufficient to widen the collar to allow for quick release.

  • Replace the collar after 8 months for optimal tick and flea protection.
