If it is a small leak and it is actually on the cat, then it is probably just a pinhold and the best way to fix it is just to weld it. They do make something called muffler cement which will work for a while, but eventually it will dry out and crack off again. If it is too big a crack to weld, or if the metal is so rotted away that welding blows holes right through it, then replacing the cat might be the best solution.
