If so, does a cat needed to be tested for heart worm before you begin a preventative like Revolution?

Hello,
This is a topic full of much debate. Most of the vet specialists feel that we should not overlook or ignore the possibility and prevention of heartworms in cats. Typically we do not test for it before using a preventative, like Revolution as most positive cats have very few worms and there is a greater chance of getting a false negative on a test.
