Heartgard Chewables for Cats is rated 4.8 out of 5 by 60.
Rated 5 out of 5 by from He Thinks It Is A Treat No problems with this product, we both love it. Easy to give, and he loves to take. Hoping one day that some company will come up with this exact type of product for Fleas & Ticks for Cats. 'We' struggle every month to apply topical Flea medication, it is a never ending fight, Every...Single...MONTH. Dogs have a chewable (like this) product for Fleas & Ticks, why not Cats?

Rated 5 out of 5 by from My vet recommends I lived in AZ my whole life, and my cat lived there for 11 years. I moved last year to Chicago and my vet said that I now needed to prevent heart-worm as it is more common in IL than AZ. Got her blood work tested before they would allow treatment, she is negative. They recommend heartgard, as they have been around the longest. The vet said that if she will not take it to crush it up with canned cat food and that most likely do the trick. I shall see how it goes, as this is the first time ever giving the medicine.

Q&A

Can I fax or email a prescription from my vet to you? Is there anything else you need?

Asked by: Mamafarron
Thank you for your question. We are very sorry, but unfortunately due to pharmacy regulations we can only accept a fax or scan directly from your veterinarian. So if your veterinarian is not able to approve the prescription via email, phone or fax you would have to mail in the original written prescription. Once the order is placed we are able to contact your veterinarian directly to obtain the prescription.

Can this be combined with the Flea5X Plus? I use that for flea & tick prevention, but I also want to protect my cat from heart worm & other intestinal parasites. I don't want to over-medicate.

Asked by: Beautybird
Yes, you can safely administer Heartgard Chewable and Flea5X Plus together.

Can Heartgard for cats be combined with either Revolution or Advantage Multi for monthly treatments?

Asked by: Pebbles3626
You shouldn't need to combine Heartgard with Revolution either as Revolution prevents heartworms and fleas so you would be double-dosing on heartworm prevention by using both.
Answered by: SuzyCVT

my cat is on Revolution right now and the smell bothers him. I find it is a little too strong for him. Could this be used in place of the revolution

Asked by: Lena
The Heartgard Chew for cats prevent heartworms, and removes and control adult and immature hookworms. While the Revolution protects cats from heartworms, fleas, ear mites, roundworms and hookworms. The Revolution does cover a lot more. If you purchase Heartgard Chews a dewomer and flea control would have to be purchased separately.

I was told that heartworm prevention medicine for cats works by actually preventing growing heartworms into turning into adults.  Also that there is no treatment for heartworms in cats, only for dogs. Can you please confirm if this is true?

Asked by: Suzanne
This is an excellent question. Currently there is no approved heartworm treatment for cats. There is only preventative medication available.

If your cat has just been diagnosed with heartworms will heartgard treat?

Asked by: justice 2000
Hello, thank you for your question. Heartgard Chewables are a flavored treatment for cats given once a month to prevent heartworms, and for the removal and control of adult and immature hookworms. Infected dogs must be treated to remove adult heartworms and microfilariae before initiating a program with HEARTGARD Plus. Please contact your vet to determine the best way to remove your cats heartworms.

is it toxic to humans????

Asked by: allysarah
Ivermectin, the active ingredient in Heartgard, can be used in humans to treat certain parasites but you should contact your doctor in case of accidental ingestion.

My cat is 15.5 lbs. My vet wrote a script for one pill for up to 15 lbs plus an additional pill for up to 5 lbs. Both are to be administeted monthly. Does this seem like the correct dosage and what would i purchase thru you.

Asked by: Jackpot37
Yes, this is the correct dosage. You would purchase one purple box (5-15 lbs) and one red box (1-5 lbs).
