I think there’s a pretty good consensus on iNat that if a tree was planted by a person, it was cultivated. It’s not like the observation is deleted if it’s marked as such.
I’d put a pet cat that was let outside for the day in a grey zone, since it’s currently reliant on its owners and wouldn’t be there if they weren’t, so it’s definitely not wild, but it’s not restrained either and could easily go off and start its own population.
