"Rescue" is a much over-used word these days. Various domestic pets are said to have been rescued when they have just been rehomed.
On the basis that some of these Lions are ancient they must have been well cared for in Romania to be still alive. I know some have deformities, but it could be argued that that means they have received even better care - it would have been so much easier to euthanase them.
To go off this specific topic, but related to it, I really don't understand why so many zoo enthusiasts these days , even ones of my age or older, are keen on modern exhibits with animals miles from the public and/or hiding behind a tree or a rock. Why does no one like proper cages? Real zoos have cages and animal houses, and as far as I am concerned allow public feeding too (visitors like feeding the animals and if the odd one should die as a result so be it). I don't expect anyone to agree with me but I think zoos should be for people and people alone (this does not mean the animals should be treated with deliberate cruelty). A "Campaign for Real Zoos" - yes please, and it would be one in the eye for both the antis and the politically correct conservationists too. I used to love cetacean exhibits and never cared if the Dolphin in front of me was the same one as on my previous visit (ideally the animals would survive but one Bottle-nosed Dolphin looks pretty much the same as the next to the untrained eye, so if one dies just buy another, call it "Flipper" and Bob's your uncle), but these days everyone seems to be the proverbial "bunny-hugger" who just "loves" animals and would agonise about such things. I suspect I'd be the only member of the Campaign though.
P.S. Just in case anyone is wondering after reading this, I don't have two heads. The other one on my avatar belongs to Fred the Green-winged Macaw, although the species was the Red and Blue in my early childhood. Yikes, maybe I've turned trendy.
