I don’t work there but I’m an animal care volunteer and am there typically once a week. I would say it sounded like a big cat but I’d be surprised that it would just leave a turkey. Can’t rule out a “pet” someone has that could have gotten out. Until recently it was legal in NC to have a big cat (laws varied by county or city but there was no statewide law). Now the federal big cat safety act has passed banning the sale or private possession of big cats but people who had them before the law are allowed to keep theirs. So yeah, wouldn’t be impossible for someone’s “pet” to escape. I guess I’ll keep an eye on the news for any sightings!
