You sink your fangs into his legs, and Rudy screams loudly. As he is cursing in pain, small tan hairs start to appear on his skin. "Whrrrat is thrrris?", Rudy exclaims in a broken voice as the tan fur thickens all over his body, forming somewhat darker stripes across his back. His fingers and toes quickly shrink into nothing, leaving just four small three-digit paws...with retractable claws? The changes proceed to his face as it extends into a short muzzle, his nose turning flat and pink as his lips recede back into his mouth, his teeth shifting to a new alignment as his incisors grow into fangs. His eyes fill with a green color, the pupils turning to slits and his ears growing and moving to the top of his skull. By now, Rudy has lost all his head hair, replaced by that same tan fur. He lands on his forepaws as he feels his legs and spine bend, a bulge in his pants getting bigger as he seems to be getting smaller. You slowly see a richly furred, twisting and turning tail coming out the back of his pants as they drop to his knees, now way too big for him. He continues to shrink until he's only about a foot tall, and looks at you angrily, his muzzle producing nothing but murrs and hisses.
He puts his back up and flicks his tail, but you give the new tan striped cat a pounce of your forepaws and he knows who he's dealing with. Now towering over Rudy, you wonder what to do with this cat...
