it might of been the lesser spotted jumping fox. Not a native species but brought over by the canadians in 2012, they tried to sneak them into the olympics but they kept biting officials & ran away, last seen heading towards your area
We'll as it is now peeing down the girls can stay in their run.
Not sure if it was a Lesser Spotted Candian Jumping Fox or not. I only caught sight of its tail so didn't have time to check its rump for a Maple Leaf tattoo.
