In a statement the team at Fota say every attempt was made by vets to save Shanto, but his condition deteriorated and they had to make the difficult decision to put him to sleep on the 23rd of February
A post mortem confirmed that he died of kidney failure
The lead ranger at the wildlife park says the team are "stunned and shocked" over the loss of 10 year-old Shanto who he says was hugely popular with visitors
He described Shanto, who was the only male lion at the wildlife park, as very interactive and curious and he says Fota Wildlife Park has become a quiet place without him and they continue to miss his majestic roars each day
