Poor little Arthur - the only kitten in the vet's waiting room full of barky dogs.
Fortunately most of our wait time was in my car because I suspect they are trying to avoid another Covid outbreak amongst the staff. Then I snuggled him while we waited in the exam roof for the vet. After that he was very well behaved although he gave me an earful on the drive home.
Anyway, Arthur is heading to the 4 lb mark, is done with his shots for a year, AND he is scheduled for the 'snip' on August 18.

Glad it’s all over with!
They will just have to endure the tortures of temporary hunger pains. Judging from their size, they won't fade away. 
Everything I know about neutering male animals I learned from watching Michelle Oakley, the titular vet, neuter everything from piglets to muskox on that show. She always makes it clear what a minor procedure it is, due to the organs that need to be removed being so close to the surface.
Compare that to females, where everything is hidden away in the abdominal cavity. So much more invasive.
