Today I received a call from Tufts with the final necropsy report on Kroni. He died from a “vascular accident,” a blood clot near his poll. He basically had a stroke.

In many ways, learning this has given me relief. Since he died, I have spent many hours wondering what I could have done differently. Should I have taken him to Tufts earlier? Had I caused the problem by giving him an IM shot? Had one of the vets missed something?
Now I know that the answer to all of those questions was no. We could not have saved him and nothing anyone did caused the problem. It was simply very bad luck.

I am grateful for the exceptional care that he received during the last week of his life and for the thorough work performed at Tufts after his death. It is good to have some closure.

I was stunned & deeply saddened to learn that your beloved Kroni had died.
Please accept my condolences.
Having a necropsy done & identifying the cause of death would be very important to me as well.
In memoriam & requiescat in pace, Kroni.
Regards,
Shoshin
I have been told that stroke is extremely rare in non-humans.
I hope this does indeed bring you comfort to know that there was nothing you could have done to save him or to prolong his life.
You did the right thing, many times. Kroni, wherever he is, knows that. And now, so do you.
