Hi, I have switched to Stronghold about 6 months ago....it covers some worms as well as fleas, including Heartworm and also covers the protection against ear mites which are a nightmare to get rid of once a cat has then (have worked with Cats Protection a few years ago and saw a poor cat in such a state with earmites that I would do anything to prevent my babies getting them!). I totally recommend Stronghold even if its a little more its not that much more. But thats just me!
