From facebook:
“We are deeply saddened to announce the death of one of our giraffes.
Our keepers and vet team are working together to establish more details after Irsula collapsed suddenly earlier today.
Thank you to all our guests for your support and understanding at this time. We will keep you updated with more information.”
Real shame. Was literally there the other week and had like a ten minute chat with one of their staff about the giraffes while watching them. They must all be so sad.
