A Tiger.

Teeth and claws bit into the cat and Merrick could feel claws biting into himself as well. That was until a second wolf joined the fun. With the grey lad slamming into the tiger, it released its hold on Merrick out of shock. The black and purple beast pushed off of the cat's chest, leaping backwards and putting distance between himself and the other predator. A guttural growl pulled from Merrick, his already thick coat bristling, making him look larger. As the boy kept the tiger distracted with his bite, the older wolf dove forward again, this time sinking his teeth into the side of the felines neck where he proceeded to thrash his big, blocky skull back and forth, tearing through the striped pelt and the vitals beneath.
