Are they testing his urine for infection and crystals? Did they consider that he might be blocked and did they prescribe an antibiotic? I’m concerned that your new vet isn’t addressing all of the pertinent issues. And it concerns me that your first vet seemingly didn’t catch that his bladder was...
I would also try this product. I’ve had great luck with it over the years:

I went through what you’re going through with my own CKD cat. Getting him to eat enough became a constant struggle by the time he was 17 or so. We had certain tricks that worked and it took a lot of persistence. When even those became less effective, we resorted to Mirtazapine. It usually worked...
I’d make sure to have her thyroid level checked. Increased vocalization can be a sign of a hyperactive thyroid. Has she been hungrier of late and/or has she lost weight?

My cat went through what we assumed was a flare. It lasted for the better part of 7 weeks. I tried several homeopathic remedies, including Lysine, and he was given antibiotics in case of a secondary infection. None of these helped him.
When it spread to his eyes (prior to that he’d primarily...
We lost a senior cat (Henry) in 2018. In the last two years of his life, he largely ignore his younger playmate (Izzy) and she learned to keep to herself. Henry didn’t hiss at her as yours is, but the end result was the same. We didn’t see a huge reaction from Izzy when Henry finally passed. We...
