Customer Reviews
Cat Heartgard Chewables is rated 4.7 out of 5 by 54.
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.

Rated 5 out of 5 by from My cat has been on this brand most of her life. I just chop it up fine and mix with a little of her soft food and she eats it all.

Rated 5 out of 5 by from Cat Loves It As far as I know the product is working to keep our Cat Heart Healthy. Vet says he is what every cat should be like. The liquid alternatives did not work for us, somehow he would always get his head turned around and lick the stuff...then I would have Foaming At The Mouth Cat. That was never fun. Vet recommended these pills, since our Cat loves treats I had no problem getting him to eat these. He gobbles it up and begs for more. Perfect product for us. Thanks!

Rated 5 out of 5 by from One of the easiest medicines to give Usually my cats spit out medicine or even hack it up after they've swallowed it. This must taste pretty good because she took it right down. Best choice!

Rated 5 out of 5 by from Ease of administration I honestly didn't know how I was going to get Abby to take her Heartgard. I knew it was flavored but we all know how cats are when it comes to anything edible. If you want them to eat it they won't. Well, she sniffed the heartgard and ate it right from my hand.

Rated 5 out of 5 by from easy to administer to pet! Heartgard Chewables : I was afraid it was going to be a fight with my cat to get her to eat it. What a surprise! she chewed it with no problems. Was the easiest medication I have ever given to her.

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).

Is Ivermectin ok for cats to take orally?

I am quite confused, as i see Hartguard's main ingredient is ivermectin, but I have had a vet tell me NEVER to orally administer ivermectin to a cat, rather use it topically? Please let me know. I take care of a stray cat outside my office and I would like to get him on heartworm prevention, but I need to know how to administer it.
Asked by: Anonymous
It can be administered orally, it just cannot be given as an injection.
