Blackfoot Forest [m] what does the fox say?

The she-wolf startled as another loud noise echoed through the wintry woods, sending a flock of chattering birds into the sky. By the time Javelina straightened, the air filled with screams. Now there was no question the foxes were shouting in fear rather than ecstasy. Had a bear attacked them, or perhaps a mountain lion? Did either one of those bark?

Before she could organize her thoughts, one of the foxes—surely the vixen, her heady scent washing over Javelina—flicked past, pursued by a beast that was neither bear, nor cougar, nor anything she had ever seen in her life. Her two-toned eyes flew wide before she scrambled to get out of the way, darting low and sideways.
