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.

Do not open until ready to use. Keep out of reach of children; do not let children play with the collar or reflectors. Choking hazard; contains small parts.

For external use on cats only. Do not use on other animals. Not intended for use on humans.
