Sometimes 'the cat' is...
Things seen, not seen...
Visiting someone in hospital, they're confused*, 'seeing' hamsters and rabbits on their bed, running around the ward, talking about 'the cat' that visited...
Then on leaving, unlocking your bike by the entrance, you see 'the cat' is actually a cat...
(that lives nearby, visits often)
