It is a tricky situation, is all I can say for now. 
Autopsy showed that Idi died of the anesthesia! A big fuus for animal rights groups in Brazil...the Great Ape Project made a lot of media out of it!
I would question that .. very much, Sir!
With anesthesia there always is a risk, however ... it is the general state of health of the individual that defines whether you can cope with it or not.
In this case, I propose there is a health reason for the gorilla male - even though it was elderly at 38 - to die from an anesthesia. It sounds that either or both the vets at the zoo really have no clue in terms of wild animal health nor getting an autopsy right.
Kifaru!!
The final autopsy was not made by the ZOO, but by a Team of Experts of Veterinary Sector of the Federal University of Minas Gerais! The Zoo stated that is was because of his health condition and well it was not accepted and a new autopsy was made and this was made public after the the autopsy runned by the university! Im sure the health condition played the biggest rule for no success of the anesthesic procedure, but the death cause was not the health condition but the anesthesic, maybe was not a good idea to do it at this time! Only that...and the seccond autopsy was a court decision asked by the Great Ape Project!
Thankyou Eduardo for posting this, I am deeply saddened to hear this and now there is only Imbi. Please let us know if you hear anything else, I met Kifta on many occasions and she was lovely
Well maybe the money involved in this transaction made Aspinall decide to sent them to Brazil!
Many news articles from the time they came to Brazil stated around R$ 440.000...around 220,000,00 USD in today exchange rate..
Belo Horizonte Zoo is the owner of the last gorilla left here...
And a more fresh news from yesterday. Belo Horizonte Municipality (owner of the zoo) confirmed yesterday that the Zoo is a focus of Visceral Leishmaniasis, with 7 cases confirmed in the animal collection by now.
Brazilian Law is very clear about it: no treatment should be done, animals need to be euthanized! So the history will get more pages in the next days.
