I read somewhere they were also offered a nice amount from another zoo to take the animal.

I think 3 days ago, I also read, another Danish zoo wanted to do the same thing with one of their giraffes. I didn't read it though, just the title.

Terrible. There is no excuse for doing something like this.
A perfectly healthy animal being put down. You don't do that with humans eather, so why with animals? Because they aren't human? That's not much of an excuse in my opinion.
