You mean that the infamous cat could collapse
his own superposition?

"There is, to be sure, a genuine problem
in the phenomenon of quantum measurement,
but I will not discuss it here.
It concerns _introspective_ systems,
where subject = object so that
the basic conception of a single subject
observing an ensemble of objects
must be modified."

Subjectively, yes. That's what we apparently do all the time. If
unitarity is to be preserved collapse must be a subjective process.

However through appropriate experimental procedures a smart cat may
detect superpositions of other cats and indirectly of it own self too .
That would deconstruct what's left of the notion of "objective"
reality in the current physical paradigm.
