Nope. The copenhagen interpretation says that the wavefunction collapses when it interacts with anything.
But the thing it interacts with is still part of a larger wavefunction until that collapses etc.
Schroedingers Cat is about this fact, the fact that a cat (an observer) can be superposed.
I have yet to work out what the difference is between the Copenhagen Interpretation and the Many Worlds Interpretation. The physical reality they describe is identical.
