Foxes are sneaky fuckers too. One intentionally scared me one day when I first moved to CO. I scared him first, and I swear he was wanting some revenge, lol.
They'd steal my dogs toys and take them back to their den. One day they were tormenting him, so I let him off the chain. He chased that asshole and found their home. He found his shit, and started bring it back, lol.
You do have to be careful, and the one that would be in our yard in daytime ALL the time was a problem even though not aggressive. They are rabies vectors and at a farm right up the road a few years back, one attacked a neighbor and indeed was rabid. Luckily he didn't get bitten and they shot/tested the fox.
They're 'foxy'...on our property you can catch them hiding in the tall grass. They also love to hide under our back deck for a bit and then ambush birds, squirrels, bunnies and chipmunks around our birdfeeders. I enjoy watching them hunt those and occasionally score one. Though I much prefer watching the hawks and an occasional eagle hunt our yard. Valentines Day last year we were entertained by a sharp shinned hawk catching eviscerating (live) and tearing up another bird about 15' from our window. Serious blood on the snow shit.
The foxes don't get away with a whole lot though...we have a family of crows that live out back in one of the bigger trees and they sound the alarm loud and clear for everyone if there's a fox on the prowl. The coyotes only visit after dark and are much quieter.
