Hi @Former-Member, I super hope today is a bit cooler for you. I can't imagine how much these crazy temperatures must suck for you if 19 degrees is your comfort level.
It got up to 47 in my part of the world, but I am blessed with airconditioning. And even when out, the heat doesn't super bother me. I went to Bunnings for a while yesterday and it was quite noticable how few people were out and about.
I'm super hoping S will be good for the vet. He has only been twice before - to get desexed and vaccinated. I was impressed last year that he was so good. He is totally unsocialised to anyone other than me. In the two years I've had him, the only people that have come to my house are the police.
Thus I had expected him to be challenging at the vet, but he was fine. I clipped his nails yesterday so that if he does freak out, he will do less damage to the vet than he otherwise would. 
I hope your day has some good in it today @Former-Member.
