Another big cat has died at In-Sync Exotics Wildlife Rescue and Education Center in Wylie.
Officials said their white tiger, Kiro, died Tuesday after having several seizures in the last couple of weeks.
A spokesperson with the animal sanctuary told NBC 5 Kiro was evaluated by numerous veterinarians, but they were unable to help him.
It's been a tough year for the rescue center. An outbreak of canine distemper has killed eight big cats since last July.
Kiro's death was not related to the outbreak.
