About Hartz UltraGuard ProMax for Cats

Why Choose a Collar?

Hartz UltraGuard ProMax Collars for Cats are a convenient, mess-free form of flea and tick protection. Not only are they easy to put on and readjust if necessary, but they can also be worn simultaneously with your cat’s other collar for up to 7 months!

How Does it Work?

Hartz UltraGuard ProMax Collars contain active ingredients that are slowly released over your cat’s entire body. The active ingredients kill and repel fleas and ticks, and can also prevent flea eggs from hatching.

Why Choose Hartz?

Hartz has developed a flea and tick collar that provides comfort your feline can enjoy, with the protection you can trust. The soft and flexible collar allows your cat to go about his day comfortably. And you can feel confident knowing that every collar is crafted with trusted Hartz expertise in protecting your cat from those annoying pests.

How to Use the Hartz UltraGuard ProMax Cat Collar

Step 1: Unroll the collar and remove the small plastic connectors from inside the collar. Stretch it to activate the ingredient in the collar.

Step 2: Place the collar around your cat’s neck and buckle in place.

Step 3: Ensure that two fingers fit comfortably between the collar and your cat’s skin. Adjust the buckle if necessary.

Step 4: Leave 2 or 3 inches of collar after the buckle for extra adjustment, then cut off and dispose of the extra length.

Questions & Answers

5 Customer Questions


have 2 cats that groom each other. are this collars safe for them?
Answer by ChewyMay 17, 2022
Since grooming is a natural instinct, all Hartz flea and tick products are formulated with this in mind. If used as directed, we would not expect a problem if your pet was to groom itself while using our product.

Safe for kids to touch that cat with this on? Kids touch all over collar head neck there no way of preventing.
Answer by ChewyMay 09, 2022
Federal law requires that every product in the flea collar category must contain the statement "Caution: Do not let children play with this collar," or equivalent statements for similar products outside this category. Our Research Department advises that normal contact between you and the cat when wearing the collar should cause no harmful effects. However, they also advise that the collar is not a toy and should not be played with by a child. Regulations also require that products in this category contain a disposal statement regardless of the hazard they present. Again, the Hartz Flea & Tick Collar is completely safe to use as directed. We anticipate no hazard from incidental handling of the package. There is no measurable amount of product residue within the packet after removal of the collar. Yet, this instruction is necessary so that people develop the habit of careful disposal of empty household product packages, some of which may present some degree of hazard. When the pet has the Ultra Guard Flea & Tick Collar on, your pet can sleep with you or your family without any expected problems. Please note that the collar does contain pesticides and precautions should be taken if the pet sleeps by your face, as you would not want to be inhaling or have prolonged direct contact with the product. However if the pet normally sleeps at the foot of the bed, no problems should occur

What is the expiration date
Answer by ChewyApr 06, 2022
The UltraGuard products do not have an expiration date. They have a shelf life of 5 years. The exact shelf life of each product, can be obtained directly through the manufacturer.

Does this work if you are dealing with an infestation?
Answer by ChewyMay 02, 2022
The collar will begin to kill fleas, ticks and 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 and tick infestations, it may be necessary to replace the collar more frequently. Additionally, we recommend treating the home or environment in the case of an infestation.
