A FRAIL lion that looks like a walking skeleton has become too weak to chew.
The skin-and-bones beast, called Ala, is so emaciated he can barely walk through his enclosure at the Jinniu Lake Safari Park in Nanjing, China.
A clip - shared later on Douyin, China's version of - shows the ultra-skinny lion wobbling down a walkway.
It caused outrage among viewers who accused the zoo of not taking proper care of the feeble feline.
One user said: "This is too much suffering. If you can't afford to feed it, send it to a different zoo that can.
"Why let him suffer? It should have been left living in nature."

Another viewer added: "This zoo is too much, starving the lions like this."
Zoo officials later claimed that the lion is so old he can no longer chew his food.
They claim that the big cat is 25 years old, the equivalent of 80 if he were a human.
Officials say he is fed a special diet of liquid protein and small cuts of meat and is watched over by specially trained vets and keepers in a private cage.
