Acting like a cat, how completely demeaning but he knew he had to when he needed Sam to help him out. The man being his best shot of returning to human form than any of the others. He noticed Sam's soft spot for cats in general and it should help him now. Plus, he couldn't remember how such a thing happened to him in the first place. There might be a great danger brewing on the horizon.

Swallowing down the rest of his pride, he nuzzled Sam's hand affectionately and purred in what he hoped would be a cute and endearing way. Bring him inside, Sam and figure things out, you bird brain.
