Dear Christopher Cat
Our cats’ heartworm tests were negative, and we’re starting them on heartworm preventive. Which is the best product?
I have good news and bad news – and finally, great news.
The good news is that heartworm disease, which is transmitted by mosquitoes, is less common in cats than in dogs.
The bad news is that while some cats show no signs of heartworm infection, others die from a single heartworm. Signs of heartworm disease may include vomiting, difficulty breathing, cough, lethargy or sudden death.
Treatment of heartworm disease is quite risky in cats, so the best course of action is to prevent infection. Indoor cats get heartworms half as often as cats who spend time outdoors, so keep your cats inside.
The great news is that the feline heartworm preventives are safe and effective, and they only need to be used monthly.
Revolution, which is applied to the skin, also kills fleas and ear mites, as well as roundworms and hookworms, intestinal parasites that can infect humans.
Interceptor and Heartgard for Cats, both flavored tablets, prevent heartworms and also kill roundworms and hookworms.
These are all excellent products, so choose the one your cats like best.
