But everything went well, and it turns out that Finn likely didn't injure himself in an accident - the fracture was probably due to malnutrition. Which explains why he was suddenly so keen on eating: He hadn't been able to find many good meals on his own.
"The fracture is also not a recent one, i.e., just a week," the National Fox Welfare Society wrote. "It was done some time ago, so it is possible mum could have dumped this little one knowing something was wrong."
As of Tuesday, Finn was well on the road to recovery - and still hungry. "Little Finn the fox cub was up and waiting yesterday evening for his cooked chicken supper, and despite the ordeals of the day, devoured the lot," the society said.
He also spent some more time snuggling with his stuffed bunny.
