Oh thank you so much for this. I am so sick and tired of using the old standby (s) for flea, tick, and mosquito prevention that are full of neurotoxins and whatever else that is not good for our furkids. I put my foot down when one of my beagles had head tremors after getting one of these preventatives - not sure which one was the culprit, but doesn't matter. Both Frontline and Heartgard are just too toxic.
