Foxes

i mean, you make it sound like it's something normal, which no, you're almost never going to meet someone who has a pet fox..
But there are absolutely people who do, and it's on about the same level as having large birds. You need a BIG fully enclosed area and daily interaction with them, and you shouldn't let them roam indoors like a cat because they'll piss on things and cause issues.

And like bird owners will say: don't get one, anyone who has to think about it isn't ready for the dedication needed.

Not pets per se, this is a wildlife rescue person, but some foxes end up not being able to be released for various reasons. So they become domesticated more or less.

Edit: this particular fox is Lana from the kikithefox account. You can find them on social media for adorable videos.
