It's not an interpretation I've ever heard that Schrödinger (or anglicized to Schroedinger -- no n before the d) was trying to disprove something with his though experiment. Also, I don't think there's anyone who believes this is true as applied to cats -- Einstein wrote "Nobody really doubts that the presence or absence of the cat is something independent of the act of observation."

FWIW, I usually hear Schrödinger pronounced SHRAY-din-jer. Is that acceptable "English"? A professor of mine used to make me knutz by chattering on about Girdle and Gerta (Gödel and Göthe).
