S1·E29 Be Prepared

When Heathcliff tries to follow Iggy to a Boy Scout camp, the scout master forbids it, saying, "A common house cat could never survive in the wild." This infuriates Iggy's pet, who sneaks along anyway just to prove the scout master wrong. Even though Heathcliff gets into all kinds of mischief in the wilderness, he leads the group to safety when they get lost in the woods, so he becomes the first cat ever to be named "Scout of the Year!"
