One of the snow leopard cubs, born at the Highland Wildlife Park earlier this year, has been put to sleep.
Keepers said the four-month-old male had colobomoa, a serious eye condition which causes vision problems and “can be very painful”.
A statement on the park’s Facebook page said: “While surgery can help to relieve pain in some cases, the seriousness of his condition meant we needed to take this incredibly difficult decision following veterinary advice to ensure he did not suffer.
“We are continuing to monitor our two female cubs, who also have this eye defect though not to the same degree at this time. Our thoughts are with everyone who works with the cubs.”
The trio were born to mum Animesh in August and were spotted exploring their new surroundings in October.
