Jasper has to have surgery. :(

What is the correct way to punctuate a sentence ending with a smiley? My grammatical instinct is to put the full stop after the smiley, in order to include the emotion therein with the sentence (in the same way as one puts punctuation outside, and succeeding, brackets). However, that looks wrong as the full stop becomes embroiled within the smiley. Putting the full stop before implies the smiley stands on its own as a sentence, which it does not, and the only other option is to leave the punctuation out all together, which is just wrong.

Or I could just use words, but where would be the point?

Anyway, his canine cavity is open from where the tooth used to be, and the poor old man has an infection. So he'll require surgery to clear out the infection and attempt to seal up the hole.

He is healthy, especially for a 19 year old cat, but in general anyway. His blood tests are coming back normal, his thyroid is under control, and our vets have a good record with this kind of thing. So he'll be fine. I'm the one with a problem with surgery, not him.

While we were at the vets - which is also an animal shelter -  I was made sad by the annoyed and frustrated lady who came in with a cat she said had been left on her doorstep by someone else, and which she refused to have in her house. When the man at reception explained they didn't have any room and suggested some more animal shelters, she left. It was only as Izzy and I were leaving that we discovered she had just leftthe catbox outside the shelter. So we had to take it in and leave them with it. Someone else's problem, I guess.

I just hope everything works out OK
