Her curiosity piqued, Vos and a colleague visited a veterinarian in hopes of confirming just what sort of animal this little baby actually was. But the vet was stumped, too.
"The one thing she was sure of is that it was a baby girl," Vos said.
Next, Vos decided to consult a nearby wildlife rescue center — and with that, the mystery was solved.
"They recognized it as a baby fox," Vos said.
Turns out, fox pups are often a darker shade very early on in life, and they do have a vaguely cat-like look.
