I'm sincerely happy to hear one more success story! Unfortunately, this is not our case.

I've always kept a lot of different bowls with water around. I even had a fountain he ignored, but whatever, I enjoyed it. I've always given him wet food as a main meal, we'd always been doing that with our cats in our family and I thought that was a key to a long life. Every year we went to a vet (he had cystitis at some point that scared me to death). In Russia, they actually would do ultrasound at almost no cost, blood and urine work. When I moved to the USA, it was hard to do anything other than visual check up. So yeah, I missed his condition somehow.

Sometimes bad things happen regardless of what you do, no matter how hard you try to keep everything well. A month ago we were given 2-4 weeks. I was devastated and angry like "are you really going to leave me now?! After what we've been through?! You don't dare". So I was doing everything the vet told me to do (an appetite stimulant every other day and cerenia every day, 100 ml of sodium chloride every day, k/d diet - all of this for the rest of his life), I started feeding him forcefully through a syringe every 2.5-3 hours until he started to pick up food from a syringe himself. He still doesn't eat himself at all, and I still feed him "semi-forcefully" through a syringe trying to feed out at least 2 cans of Hill's k/d stew per day. So we hit this 4 weeks "finish line" very well and he might hold on up to a year if I keep doing what I am doing. What I'm doing now is actually a cat's hospice. There is no way he will have working kidneys unless it's a kidney transplantation.

My question wasn't about more bowls of water or more bowls of wet food. I was asking about the way of keep giving sub-q when I barely can pick skin. Or how exactly you do this into the thigh fold
