@tsarstepan,
tsar, I would want the same ideal--animals living unmolested in the great clean wilderness. The chances of this happening are remote. Wild animals in captivity is far less than ideal. This may ulitmately be the only place for some species.
The tiger in questions certainly appears overweight. However, I read about this tiger. It does have acitivities and exercise access. Is it miserable? I don't know? Neither do you.
