I'm not a germaphobe in particular. But Fox are basically giant furry carnivorous Rats, more paralells than differences . I wouldn't have any hanging around my yard.
They've had outbreaks of Echinococcus here. They figured out the infection path was most likely Fox and/or Mouse to Cat, Cat to playtime sand box, sandbox to child.

We were tasked to cull all Fox and Feral Cats. Fox were pretty much shoot on sight for 15 years.

I enjoy watching the Kits play in the early evening near the den. But the possible consequences can be catastrophic. I handle Fox and Yotes like toxic waste just in case.
