Questions & Answers

do I use the Howe tube on one cat if so do I put it all in the same spot yes or no
Answer by ChewyMay 24, 2019
The entire tube should be used on one cat. Prior to application of the product, gently lift the cat's or kitten's hair coat on the back of the neck at the base of the skull, position the tip of the tube on cat's exposed skin and squeeze out the entire contents of the tube onto the cat's skin.

Will this make your cat drool if they ingest by licking application area
Answer by ChewyMar 04, 2021
This treatment has a bitter taste, oral exposure could result in salivation. Be careful not to get any product in the cats mouth while applying.

How long will it take to start killing fleas?
Answer by ChewyAug 03, 2021
The UltraGuard Flea & Tick Spot Treatment for Cats is used to kill fleas and deer ticks. To prevent future infestations for up to 30 days, it stops only the adult fleas and the product also repels mosquitos. The product does not repel adult fleas from jumping on your pet and the product does take some time to breakdown these fleas. If you are seeing adults fleas reappearing on your cat, we recommend two solutions, treating the surrounding environment and flea combing. Treating your home and yard will breakdown fleas before they have a chance to land on your pet. If they do happen to get to your pet, they will eventually die once they come into contact with the product. If you would like to stop this more quickly, flea combing your cat and then placing the fleas in a water and Dawn dish detergent solution is one of the quickest ways. With each flea caught and placed in the water, wipe the comb clean and then comb through the cat again.

How long does it take for this to dry?
Answer by ChewyApr 29, 2020
The length of time it takes the treatment to fully dry will vary.

Definitely Works

I bought this for the abandoned cats outside, and only one of them allows me to pet him. I treated that one cat with this, after finding a good-sized on him and he's quite fluffy. After treating him with that first dose, that tick was dead within 48 hours. I've never gone wrong with the Hartz brand for flea & tick treatment and I will continue to use this. I will buy this again

Didn't work for me

This Hartz flea & tick treatment did not work for my indoor and outdoor cats. I waited for days for them to have some relief from the fleas. I am still looking for something that will kill their fleas and keep away ticks. Try something else :-(

Doesn't work

I have worked in vet clinics and humane societies all the cats I have seen that have been put on this are always covered in fleas, it's cheap for a reason, it does not work.

Not Good For My Cat

I put this on her and within 5 minutes she was bolting around the house, crying and trembling. The smell was really strong and I thought maybe she just wasn't used to it but after about an hour...she was no better. I wiped some of it off and she seemed better but was still antsy and not looking right. I ended up bathing her to get it off. She hates baths but she let me put her under the water spout for relief! I feel so terrible. I will not buy this again. Listen to the reviews. I should have.

In and out cat.

My cat wants to out every day and I so far have not seen her itch and I have not seen any fleas in our apartment.
