How To Apply Seresto
- Step 1
Insert the end of the collar through the buckle.
- Step 2
Adjust the collar around the cat’s neck without it being too tight or too loose. It should be possible to insert two fingers next to each other comfortably between the collar and the neck.
- Step 3
Pull excess collar through the loop(s). Collar length greater than 1 inch beyond the loop(s) should be cut off unless it is on a growing kitten.
- Step 4
Three reflector clips may be fixed permanently to the collar to increase your cat’s visibility in the dark. Evenly distribute the clips on the non-overlapping part of the collar. The clips are correctly applied when a clicking sound is heard.

Scratching may be observed occasionally in cats that are not used to wearing collars during the first few days after fitting. Clients should ensure the collar is not fitted too tightly. Slight hair loss and mild skin reactions due to the mechanical irritation of the collar may occur at the application site; this usually clears within one or two weeks without the need for collar removal.
