And of course, idiocy unleashes. Kya's first-born cub was born outside the maternity facility, and the inexperienced lioness apparently injured it while transporting it there. Her three others are doing fine. But the idiocy of the haters followed up in comments to the report:
Keep killing 'em OZ! Don't let the perversity level drop. It's for the children!
I'm the first to condemn stupid practices at the zoo - but this isn't exactly their fault, as less is known about lion births than, say elephant births. That's why I jumped on them after their management nearly "managed" to get Samudra killed - rather than taking competent advice and restraining a first-time mother during the birthing, they decided that she should be "free". And what happened following the birth was exactly what they were warned about: not knowing what that was, she tried to kill it. Intervention saved the calf, but put human lives at needless risk.
The cub death was nothing like that. Kya inadvertently caused a crippling injury during transport; she didn't actively seek to kill the cub, she just wasn't aware of what her jaws might do to the new arrival. There simply aren't enough data regarding lion reproduction for animal care staff to have pinpointed likely first birth.
African lions are not endangered species, and so have not been subject to as much intensive study as have endangered species.
