if you are putting your turrets in the right place, Karthus is losing farm and wasting mana by going after them, not to even mention getting way closer to Heimer's rockets than he should be. Karthus can be handled easily by a Heimer that harasses well and keeps his turrets far from the minion line.

Caitlyn on the other hand is a hard counter... she WILL destroy your turrets as soon as you place them practically no matter what you do, even your ranged rockets won't hold her back, as she can harass you forever with autoattacks from safety between your long cooldowns without you even having a nice safe turret nest to run behind. Lane swap if you are facing her or be prepared to buy armor and a lot of potions just to be able to farm...
