I hope Yoda gets better, and that it turns out to be nothing more than a temporary feeling "off color." Kidney disease in cats is scary because it seems to unpredictable... and cats are so good at "hiding" there's anything wrong till it's too late.
We used to have one — Raddish — who was (no so) fondly known as "Slash" at the vet and required the shoulder length welding gloves to be handled.
Anyway, wishing a speedy recovery to Yoda!

He is eating better since I changed his diet so I'm hoping for the best
