No knowing for sure

I saw a cat lying on the street
her hindlegs crushed to a pulp
already given up on any hope to live
Road accident had met her
aiming for a roadkill soon after

I tried to make sense of the mess
Took her upon my arms
Not much resistance, not much life
Rushed off to rescue her,

and I did, somehow, with a help of an expert vet
She is back now, sans the mangled legs

I then took her home and gave it
Took care
Gave love, then some more
and saved her

My epitaph shall read:
"Or did I?"
