As Io picked up the volume of her growls, Sirius would do the same, his deep voice a threat of violence and Marshal screeching eerily above. Bast keep past with Io, acting as her support, and adding to the general ruckus. As this point, the unlikely team of predators had scared away the rest of the herd. He could still hear the stampedding of their retreat, and knew it would be a few lands over before the beasts settled again. No matter, they had what they wanted.
Marshal let loose a different pitched cry, a warning of the cliff to come. Sirius kept at it until the end, veering at the last possible second, setting a skittering of stones over the edge, and almost the loss of his balance. He was a heavy set monster who didn’t turn as easily as Little Io or Bast. The cat easily reached the end, and diverted her pace along the edge of the cliff. The Ox would see their fate at the last, driven by fear and pain in a blind panic, and then the cliff was upon them. The leader didn’t stand a chance, thundering head first over the urge with a sickening crack. The second came to a sudden stop, teetering upon the edge, until Sirius threw a back kick into its side with all of his weight, almost going over a second time as he sent this Oxen after its companion.
He then turned, and ran along the side, chasing the long way down the cliffside, where he intended to find the one he could still hear thrashing after its fall. He had to let his bloodlust out somehow.
