We use Interceptor with no problems at all and I also have one with many health issues.
Heartworm prevention is the only thing I do regularly. I would not skip a month even though we are in an area that gets cold winters and lots of snow, as you can always find an errant mosquito. And my girls are indoor pottiers only. My vet also recommends heartworm prevention for indoor cats as there have been lots of indoor animals dying from heartworm in our area.
Heartguard is a heartworm prevention that has a very high incidence of reactions. My vet also concurred that you cannot cut the dose in 1/2 as it is not spread evenly throughout - so the up to 25 lbs is the smallest dose available.........
