I worry about my cats getting heartworm. They both live indoors, with supervised visits outdoors. Last year people kept leaving the main door to our apartment building open and we would get lots of mosquitos in our apartment. I was told by my previous vet that there isn't even a definitive test for heartworm in cats. Is this still true? Also can I have my cats on both Frontline and Heartguard? Thank you.
Yes, there is a test avail and you can start the cat on heartgard for cats. Yes, cats can have both heartgard and frontline. vetcare
