>>2580200in the UK, trespass is a civil offense. You're not committing a crime for being on someone's land. That can turn into criminal trespass if you idk, break shit to get in or whatever, I forget the specifics of the law.
What's more, *foraging* on someone's land is also not a crime. In fact, if you forage on their land (that is, take something they are not actively cultivating that just happens to be there, like wild mushrooms, blackberries in hedgerows, etc) and they attempt to take your foraged good, *they* are the ones committing a crime as that is attempted theft of your personal property.
As a fun final point, cats in the UK are granted express 'right to roam' privileges via the Animals Act 1971. So in a sense have more freedom that people in that case. If it causes damage or whatever, then the owner could potentially be held liable since cats are their 'property', but Mittens has every right to wander wherever she pleases.
The UK's got plenty of other problems (extending right to roam to people outside of scotland, for instance, would be fucking amazing) but our trespass and foraging laws are, in my mind, one of our great advantages. That and some cunt with a shotty isn't gonna shoot you just for wandering across a few metres of his field because 'muh castle doctrine'. Also while we're pretty low on dangerous predators and biodiversity in general, we're really pushing to reintroduce a bunch of stuff, like beavers, wolves (in scotland do deal with the massive deer overpopulation problem, much like I hear Wisconsin is doing), native flora, there are a bunch of breeding pairs of golden eagles back again.
