One thing about Tybalt having had his teeth cleaned (for the first time in his life): he's even more desperate for affection, especially in the wee hours, than ever before. I've spent most of the last 3 hours cradling him in my arm while he purrs and makes happy grunting sounds, with my other hand cupping the top of his head. (Try that with your cat who likes to be scritched there, and see if it works.)
This despite the fact that we're still prying his mouth open and spritzing strange fluids into it twice a day. Which, together with his liking to butt his head in my face, another feline sign of affection, leads to the other thing about Tybalt: the teeth-cleaning has made a heck of an improvement on his breath.
