Hmm I've never seen a tick jump, but I've seen fleas jump . I've killed plenty of ticks and fleas for the protection of both dogs and people, but I do it quickly. I have no desire to make something suffer. Creatures are only doing what nature tells them they must to survive, and my heart will never take joy in the killing of anything. When it needs to be done, it will be, but I have always been extremely sensitive to the sanctity of all life.
