Favour timeline — who owns each window

StageFavouredWhy
Level 1KatarinaLevel 1 Katarina: your dagger trades beat her mana-hungry, poisonless E pokes before Q enables anything.
Level 2KatarinaLevel 2 Katarina: Q-W trades punish every Noxious Blast she throws at the wave, and she can't kite you yet.
Level 3KatarinaLevel 3 Katarina: Shunpo converts each Q miss into a burst window her Twin Fang ramp can't answer in time.
Levels 4-5KatarinaLevels 4-5 Katarina: your all-in outpaces her DPS as long as you don't stand in Miasma, and Q remains dodgeable.
Level 6KatarinaLevel 6 Katarina: Petrifying Gaze is her only stop and it's negated by attacking from behind or turning — then Lotus wins clean.
First itemKatarinaFirst item Katarina: Lich Bane burst kills her inside three seconds while her Seraph/Rylai build needs long fights and mana she doesn't have yet.
Two+ itemsKatarina2+ items Katarina: the assassination still wins off a flank — she must face you to fight, feeding your positioning-based entries all game.

Early game (levels 1–5)

Levels 1-2 you win comfortably: Cassiopeia has no boots by design but no kite tools yet either, and her E-only trades cost heavy mana without poison up. Bounce Q daggers off the wave and take short trades whenever her Q Noxious Blast is down — it's a slow, dodgeable circle with a clear windup. She wants to shove with Q on the wave; every Q spent on minions is a free walk-up window for you.
