After Martha died I got her sister Amelia checked at the vet to make sure she didn’t have similar kidney problems. This involved a blood draw, which made her extremely unhappy and bitey, necessitating a cone:

The good news: her bloodwork came back clean, so she’s a healthy cat — except for her teeth, which had plaque, and a few teeth have died and will need a later extraction.

Poor kitty won’t like that, but I’m glad she’s otherwise healthy. I need to start brushing her teeth.
