@pkok I'm sorry. Your cat is broken. Please send it to me for repair.
@Surasanji well, she won't stop making a resonating sound. Is she too damaged for repair? Could I file for a replacement maybe?
@Surasanji the sound only increases! She stopped moving, except for the front paws, going in a somewhat anti-phase motion of opening and closing.
@Surasanji Oh my! Moving the kitty made it stop and activated the stubs-related movement mode.
I think it is fixed for now, but not sure if either of us is happy with this solution. I will try again to invoke the symptoms!
@pkok hehehe
@pkok Yup. Sounds like terminal purrosis. You'll have to keep with the treatment, and move the kitty to your lap or otherwise shower affection onto it.
