Hartz Ultra Guard Plus Flea & Tick Collar for Cats & Kittens is formulated with a substance that is deadly for ticks and fleas, yet extremely safe for cats and kittens. The tick collar has a light perfume that gives your cat a clean, fresh smell. With Hartz Ultra Guard flea & tick collars, ticks, fleas and eggs are killed within days. The flea and tick collar works for around 7 months.

Place the Hartz Control Pet Care System Ultimate Flea Collar around the cat's or kitten's neck, adjust to proper fit and buckle in place. The collar must be worn loosely to allow for growth of the animal and to permit the collar to move about the neck. A properly fitted collar is one that, when fastened, will snugly slide over the pet's head. Leave two to three inches on the collar for extra adjustment and cut off and dispose of the extra length. Some animals may become irritated by any collar if it is applied too tightly. If this occurs, loosen the collar. If irritation continues, remove the collar from the animal. This collar is intended for use only as an insecticide/IGR generator. The collar will begin to kill fleas, ticks, flea eggs and larvae immediately. Its full protection against harder-to-kill ticks will be built up within a few days after being placed on the pet. For continuous flea and tick protection under normal conditions, replace the collar every seven months. Under conditions where pets are exposed to severe flea or tick infestations it may be necessary to replace the collar more frequently. Wetting will not impair the collar's effectiveness or the pet's protection. If the pet goes swimming or is out in the rain it is not necessary to remove the collar. The Hartz Control Pet Care System Ultimate Flea Collar may be worn with a regular collar.
