That is the most likely. But of course ocelots dont live up there, so if it was, it was a escaped pet. I talked to my buddy who is fairly senior in the Washington State Patrol and he said he hadnt ever heard of anyone having ocelots for pets, but he then said “there’s all sort of crazy shit out there”. He said altho ocelots arent specified he’d thinks that they’d come under “Other dangerous animals”…It is illegal to own animals that pose a threat to people, livestock, or domestic animals, and it is illegal to possess any wild animals.
Chapter 16.30 RCW
But they arent in pet stores.
So, it is unlikely but not impossible.
