Reminder: preventative for heartworms in cats

Thread rating:  |
MaryL - 07 Apr 2007 16:05 GMT I was reading a message in another group from a member who has received the distressing diagnosis that her cat has heartworms. I would like to take this opportunity to remind everyone that heartworms can be prevented, but there is no reliable treatment if our cats are infected. Heartworms are much more common in dogs than in cats, but it is *much worse* if cats are infected. Please read this document from the American Heartworm Society: http://www.heartwormsociety.org/felineheartworminfo.htm#canine
I use Heartgard, and I use it all year around because I live in East Texas (where the protocol calls for monthly use). If you live in a northern state, your vet can tell you which months are the ones where you need preventative treatment. Heartgard is a very large, flexible (pliable) tablet. I pull/twist it into little pieces. My cats detect it in their food and will not eat it, but they will eat it when I mix it with tuna. Many people use Revolution, but I will *never* use that product again following an adverse effect on my cats (as I described in a message that I posted on April 5).

22brix - 07 Apr 2007 17:14 GMT MaryL,
Thanks for posting this reminder--it's a great service. As you may (or may not!) remember, I've had two cats with heartworm and it can be hideous--one of them had to be euthanized because fluids would build up around his lungs and he would have difficulty breathing. Many cats die suddenly without any symptoms. Prevention is so easy and well worth the money spent. I don't remember now but I probably spent over $1000 on the kitty who was eventually euthanized and several hundred on the other cat. I also live in a mild enough climate that we use prevention (Heartgard) every month.
Thanks again for posting this.

I really didn't know much about heartworm in cats until my cats got sick with it. I knew it was a problem in dogs and in fact have given heartworm preventatives to our dogs, never realizing cats could get it. And you're right, there's no treatment for it in cats. I've heard of surgery where the heartworms are removed from the heart of the cat but it's extremely risky and I don't know how many vet hospitals do it. Maybe more in the East and South but not too many in California. From my understanding, they can only do that type of surgery if the heartworms are visualized in the correct chamber of the heart and for the life of me I don't remember which.
It's not very common but people can get heartworm, too and can be very serious.
Thanks again for reminding all of us--it is such a preventable disease and I would hate to see any cat go through what my cats went through.

Heartworm is something that I have never come across before, so the information link that you provided was very useful indeed.
In recent years, we have experienced more and more plagues of mosquitoes each year as the summers get hotter and the air becomes ever more humid too. I wonder if this is something that all of us in the UK should be thinking about as well? The reason I ask, is because if we have mosquitoes, then surely we run the risk of heartworm too?
I also wonder if it is something that we should treaty for routinely when we are giving treatment for worms and ticks as a precaution , or have no reason to worry about it?
Advice would be most welcome. Thanks, S;o)

Or, do some of our UK friends (and other regions of the world) already have some information that you could share?

I don't think it's considered to be a problem in the UK YET but there are several articles on line regarding heartworm in the UK. Most of them talk about heartworm in dogs but just remember that where dogs can get it, cats can, too. It sounds like the problem is mostly in pets that have been abroad.

I had no idea that some of your feline family had cases like this. I most certainly feel for you- You have enough to worry about without your latest distress to cope with. You have our support & are in our thoughts too.
Thank you so much for the links too. I found them very informative, as I did Mary's posting as well.
I did a tiny bit of research on the subject, & it seems that there was a good reason to start thinking about protecting our cats, rather than waiting for the problem to come to us, then having no chance to treat it, through simple precautionary medication. I will post a link to what I managed to dredge up from Googling & Ask.com too. It seems that there is a problem over here, even though it is not as wide spread as the USA Heartworm infestations that you seem to have to cope with.
It would seem that we have a similar type of worm that has been spread via foxes, but brought into our country via dogs and cats visiting Europe on our new pet passports that were introduced recently (in their great wisdom!!)
I am going to post a link here in case there are other Uk'ers that are not familiar with the problem, as I am sure that they are not informed of it, any more than I was...
In fact I am quite shocked that we are not informed about this by our vets either. I do have a question though. Is there a difference between lung worm & heart worm? The reason I question this, is because it didn't make it clear. I read a couple of articles about it & the general consensus is that Revolution was the best all round product to cover most of them. But having read Lynn's post I see that I might be misinformed here?
If any one could suggest a better product, I would be most grateful if you would post about it. I am new to this problem so I have no idea what is best for them & would appreciate your opinions on the products & why you would choose that particular product. I have a sneaking suspicion that the reason Revolution & Stronghold were mentioned was because the sites were built by their manufacturers. Thanks again to all of you, S;o)

But > having read Lynn's post I see that I might be misinformed here? I use Interceptor for heartworm and intestinal worms, and Frontline Plus for fleas and ticks, on both my cats and my dogs. I use the 'Plus' variety because it also kills ticks, which we sometimes accidentally bring home on our clothing from the woods.
I started using Interceptor years and years ago because I had Shetland Sheepdogs who can be very sensitive to Ivermectin, which is the medicine in most if not all other heartworm preventatives. I wonder if cats aren't sensitive to Ivermectin, too? Several people have posted about cats having adverse reactions to Revolution, IIRC.
Interestingly, a past vet used the same combination on her dogs and cats, even though her practice didn't carry Interceptor (so she was more than happy to write prescriptions for me to be filled elsewhere!). She told me it was the best way to go in her opinion. My current vet also uses this combination. The only downside is the expense, but if you can buy on-line, you'll save a lot of money over what most vets charge. Just be very, very sure to buy only from reputable on-line retailers. There are a lot of phoney products being sold on-line. I buy Interceptor and Frontline Plus at www.xfleas.com, which has the best pricing for authentic products that I have found, as well as free shipping to the US. Shipping to the UK may be cost prohibitive, though.

It's flavored and chewable, but my cats won't eat it. It's small, though, and easy to administer. Placed far enough back on the cat's tongue, it goes right down (I hold their chins up and rub their throats, of course). It could also be ground up and sprinkled on food, but I prefer not to do that in case they don't eat it all.

My experience with heartworm kitties was several years ago so I'm NOT having to deal with that right now, thank goodness!
I looked at the site you posted--very interesting. I do some parasitology as part of my job but I'm not that familiar with animal parasites. Both "traditional" heartworm and this other bug are loosely categorized as roundworms but their modes of transmission are different--one by mosquitoes and I guess the other by snails. It looks like Interceptor would be an appropriate preventive--the active ingredient is milbemycin oxime which is one of the drugs listed. I don't know if cats get this, too. I just can't imagine most self-respecting cats being too interested in snails!

I appreciate the trouble that you went to & the advice that you were able to give me too. I can't find Interceptor readily available in the UK, so it looks like I am going to have to send away for it, or find out if any other manufacturer sells it under a different brand name..?
( although, even doing that is less than desirable having read on here somewhere recently, that it is better to avoid medicines from sources that could possibly be suspect??)

If it moves, Biffy is game for trying it, ROFLOL..It doesn't even need to be legged; either in 2 legged or 4 legged or even a million legged.... Biffy's other pet name is The mobile Dust Bin, because it it doesn't grow, he will eat it. I have never had a cat quite like him..He certainly is Unique, lol;o) S;o)

I treat my cats with Interceptor year round. I considered switching them to an all-in-one flea/heartworm product, but I am going to stick with what I know works (Interceptor and Frontline Plus, for all my animals) and what doesn't cause any reactions or other problems for them.
> Thanks again for posting this. Agree again. I don't think many people use heartworm preventatives on their cats, but they really should. My vet was even surprised when I asked for Interceptor for the cats when we first started going to him. I like that it prevents intestinal worms, too.

I'm so sorry > you all went through that. One of the cats did great--the only (and very scary!) symptom was an episode of syncope where he lost control of his bladder, his gums were pasty white and he was staggering around, almost unable to walk. He was yowling the most heartbreaking meow--he seemed to be in pain and I think was also totally freaked out. My vet said he almost died, most likely an adult worm blocking a blood vessel--ten minutes later he was asking for his breakfast. He never had any other symptoms other than an occasional cough. He finally tested negative 3-4 years later--both my vet and myself were doing happy dances around the room!!
With the other cat, we initially noticed he was breathing with a little more effort than usual--like he was having to force the last bit of breath out. He had chylothorax--the vets would remove 80 to 90 cc of this thick milky fluid from around his lungs, he would feel better for a while (three or four weeks at first) and then they would have to take out more fluid. He started needing fluids removed more and more often, finally only after a day or two. The pleural tissues started to adhere to each other, making it impossible for them to draw off any more fluid. We finally had him put to sleep when it became obvious that he was no longer responding to treatment and began coughing up blood. It was a horrible thing to watch, so helpless because you really couldn't do anything. He was a young, sweet boy and deserved to live many more years. I felt (and feel) so guilty for not using preventatives before that and I certainly learned that lesson painfully. I hope by reading this somebody out there will decide to start treating their cats--an awful disease and totally preventable.

That's great. Most of my cats love the Heartgard chewables it's a big treat for them. We are lucky to be in an almost flea free environment (dog gets flea prevention, cats are indoors and treating just the dog and one of two of the cats seems to have kept it that way). I grind up an Interceptor tablet and add it to a little canned food for one of my more finicky cats. She had a weird reaction to Revolution several years ago and I've been afraid to use it since.

How may vets encourage their clients to put their cats on heartworm preventatives? I know that none of mine have. I made the decision completely on my own, and as I said, it shocked one of my vets that I have them on it. I'm glad this is being discussed on this ng now, at the beginning of mosquito season.

She had a weird reaction to Revolution several > years ago and I've been afraid to use it since. I guess I am a mean mom. I just shove the Interceptor tablets down my cats' throats. It's easier with Rudy, my 3 year old, because he's used to it. I show him the tablet so he knows what is coming, and he'll just lay wherever he's laying and let me do it. He knows he will get a treat right after and it's not a big deal to him. Now if I try to give him liquid meds, that's another story altogether! He lets me do it, but he always foams at the mouth and coughs and it's just awful. We try to avoid liquids. Levi, the little one, isn't fond of being pilled, but I'm quick and he doesn't mind the treat after. I'm sure he'll get used to it just like Rudy did.
I probably don't need to give them the flea treatment every month since they are indoor only, but I don't want to risk fleas. Rudy got tapeworm one summer when I slacked off on flea treatment because we didn't seem to have any. Clearly we had at least one and he ate it. Worms gross me out so badly that now I just treat everyone--dog and cats--on the same day once a month. I give the Interceptor year round (to keep intestinal worms at bay), and I give the Frontline ~9 months out of the year. That is probably overkill, but since it's not absorbed into their blood stream like some of the topicals, I am okay with that.
I considered trying the topical that also kills mosquitos, too, but after reading about some of the adverse reactions here, I am not keen on changing anything.

I don't remember my own vet saying much about heartworm in cats until after my two were diagnosed. I think it kind of shook them up--I remember more than one vet saying the second cat couldn't have heartworm because it was so unusual. It just wasn't that common in this part of California. It has become much more common but still is endemic only in small areas around Northern California, I just happen to be unlucky enough to live in one!
