One collar per animal to be fastened around the neck. Remove the collar from the bag directly before use. Unroll the collar and make sure that there are no remnants from the plastic connectors inside the collar. Insert the 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). Excess 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.


Keep the collar in the bag and in the outer packaging until use. As with any pesticide product, do not allow small children to play with the collar or reflectors, or to put them into their mouths. Avoid contact with eyes, skin or clothing. Wash thoroughly with soap and cold water after fitting the collar. People with sensitivity reactions to the ingredients of the collar should avoid contact with the collar. Choking hazard. Contains small parts. Do not place collar or reflectors in mouth. Not intended for use on humans.
