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

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.

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.

Super helpful

I purchased this collar after a housemate of mine recommended it. It comes in a round tin that pleased me very much. Inside are two collars wrapped in separate plastic bags. When you open one, you'll find that the purple collar has a bit of white powdery residue all over it that I believe to be the insecticide. My 2 yo male cat spends time both indoors and outdoors. He likes to play with the other outdoor cats, many of whom are unfortunately covered in fleas and had given some to him last month. I restarted my cat's monthly flea medication, which I had unfortunately neglected, and the collar provides extra protection. Since it arrived in the mail, he's been out of quarantine and is able to go outside again. The collar is doing a great job of keeping his friends' fleas off of him. I loosen it a bit when I brush him and tighten it again before I let him outside, but I plan to keep it on his neck until the 7 months are up.

Flea infestation a week after using

Have to say I'm disappointed in this product. I found a flea on one of my dogs, I have 2 dogs and 2 cats. Check the other animals with a flea comb. Nothing. So I bought these as a preventative measure. All 4 animals a week later were totally infested. Ended up bombing the house and flea baths and giving them a different medication. Won't be buying again. It's the first time they've gotten fleas like that.

Waste of money

I bought these instead of seresto this year because they’re cheaper and had good reviews. They came in a similar tin as seresto but they did absolutely nothing for my cats, they still have fleas therefore I wasted a ton of money that could have went towards better collars. Do not recommend.

Smells good, but that's about it.

I have 4 indoor & 2 outdoor cats. I bought these as a cheaper alternative to Seresto... I should have spent the extra money. They smell good, but sadly about all they did was make all the fleas go to the cats heads.

DID NOT WORK

We have 5,1year old rescue cats that are in and out cats. We have had these ultra Guard Pro Max collars on them for 5 weeks. 4 of the 5 cats still scratching continuously. We can comb them out and get 6-12 flea's every time. I know these are 7 month collars but I feel like 5 weeks is sufficient enough time to curb the fleas.

Pretty Purple Protection against pests

Fleas can definitely become a huge problem in our household so these are perfect. They fit easily and I’m so happy they last seven months. I have a female cat who is elderly and allergic to fleas, so bad she will lick herself bald trying to get rid of them. I will have to buy a couple more packages because we have five indoor kitties and four outdoor. I like that these come in a nice tin, then are individually wrapped because of my total count of kitties. Purple is a great color for all of my cats and since they all wear collars these won’t be uncomfortable for any of them. These collars protect, repel and kill existing fleas then kills eggs, even larvae to prevent infestations, which is a powerful thing when it comes to keeping fleas under control. One of my cats can handle topical flea drops and foams at the mouth and my vet said she is extra sensitive to the ingredients in the solution. This works well for her and doesn’t overload her system. Harts you’ve done it again!!!

HARTZ Ultraguard ProMax purple flea & tick cat collars

I received a complementry sample from HARTZ in exchange for my honest opinion of their Ultraguard ProMax purple flea & tick cat collars. I first noticed the insecticide isn't released until you pull & stretch the collar so no worries of getting it all over your hands.The collars are adjustable to fit comfortable around your cats neck. Best of all they really work killing live fleas, preventing new hatching larvae. I feel so good knowing my kitties are protected and I can have them home delivered thru CHEWY.com.

Great Collars That Work!

The Hartz UltraGuard ProMAX Flea & Tick Collar has worked very well for our family. I actually saw a flea on one of our dogs a few days before we received the Hartz collars for our cats and dog. Since using the collars, we haven’t seen any more. Two collars come in the tin for the cats. With their comfort technology, these collars are comfortable and adjustable for any sized cat. It’s also very easy to use. Just open the package, pull it apart, insert the collar into the secure dual buckle system, put it over your cat’s head, tighten, and cut off the excess collar. I love that I can easily get it on and off but my cat can’t. Though, it does have pre-determined break away points if my cat get herself caught somewhere, giving me peace of mind. It’s very soft and flexible. After initially putting it on her, she seemed to not even realize it was there. I love that it offers full body protection. It prevents fleas from hatching and it kills and repels fleas, ticks, flea eggs, and flea larvae for 14 months. So far, it really seems to be working. My cats and I highly recommend it! I received this item to try in exchange for an honest review. My opinions are 100% mine and of my cats.

best flea & tick collar

I love Hartz products, they're so reliable and work great. When I got these to try out, I was excited because I hate seeing them scratching all the time. I like that these aren't stiff like other collars, these are soft and flexible and move with your cat. The dual buckle system keeps collars securely on. They offer head to tail protection from fleas, ticks, flea eggs, flea larvae and prevents flea eggs from hatching. They're durable and provide 7 months of protection. Two collars come in a container giving you a total of 14 months protection, unless you have more than one cat. They're very easy to use and I love that they're purple.
