| " HEARTGARD for is an oral chewable for use in dogs and puppies and for cats and kittens as a heartworm preventive. HEARTGARD chewables contain Ivermectin, which works to kill the immature form of heartworms. It is effective against larval heartworms (the microfilariae that circulate in the blood) but not against adult heartworms. Heartworm is not typical in cats and is more commonly infectious in dogs. In cats, when the heartworm larvae develop in the heart, it is likely to move to other parts of the body. " Product codes: 00002318 no | |
