A total of four Maine Coon cats came together to bring Church back to the big screen in Dennis Widmyer and Kevin Kolsch’s Pet Sematary, with cats Tonic and Leo primarily playing the iconic cat in this year’s new adaptation of Stephen King’s classic novel; Tonic played the role of a living Church while Leo took over whenever Church was required to be, well, undead.

We’ve learned the sad news tonight that Leo has passed away.

After filming wrapped on Pet Sematary, trainer Kirk Jarrett adopted Leo and gave him his own Instagram account, which racked up over 15k followers. Jarrett frequently posted fun photos of Leo, including shots from the set of Pet Sematary. He had noted in a recent interview, prior to the film’s release: “Leo is a confident sit-stay cat. His role is as the undead Church; that was his whole purpose, to be the poster child. The cat you see all across the different platforms, and in the trailer, almost any time he’s in in the undead makeup—that was Leo.”

Jarrett wrote over on the Instagram account tonight, “It is with great sadness that we tell you that Leo has passed away. He will forever be missed by his human and fur family.”

“May his star always shine bright.”
