What a treat!
My cat Duchess is an indoor cat and always has been. At one of her early checkups the vet asked me about heartworm. He told me that even though she is an indoor cat mosquitoes can get in doors as they open or even on people coming in. I really never thought about it. He suggested Heartguard once a month. I thought - She will never take medicine willingly, this will be so hard. But not at all-she eats them as if they were a treat. I just take out the box and she comes running. Thank you!
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.
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.
Works great but wish the tablet was smaller as I have to force it down their throat. At times one of them will eat it own their own but can't count on it.
Our Siamese cat, Chloe, always eats the Heartgard without hesitation. She is an indoor cat, but gets Heartgard year round as a preventive measure.
The difference is the size of the cat it is used for.

Heartgard for cats is just Heartgard, not heartgard plus. Heartgard for cats only contains ivermectin which protects against heartworms. Heartgard plus for dogs contains 2 drugs and protects against heartworms, hookworms and roundworms.
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.
