Roleplaying Naberius' influence if you can't talk?

Say you were playing as a Tibbit Binder who spends her adventuring day entirely in cat form, and you made a bad pact with Naberius this morning. How would you roleplay Naberius' influence in this case?

Plonk your butt down in front of people's legs and meow at them. Jump up onto the highest object and yowl incessantly for whatever number of rounds is required.

That's probably the most hilarious and least mechanically problematic option, so I'd like to go with that, personally. More ideas are welcome, of course.

Wouldn't Naberius' influence all but force you to take humanoid form and have at? All the cantankerous kitty routine is cute, but as written I would suspect you would be stuck decatted. Just my 2cp.
