Can diagnosed withy renal failure

Matthew suggested I post over here. So here is my story.

After a new kitten arrival my Bengal (aged 8) stopped eating. My vet and I
were pretty convinced it was the kitten causing it because after a few weeks
he got very grumpy around him. Anyway to cut a long story short when his
appetite didn't pick up and he had lost over one pound in weight, we had a
trip back to the vets who did blood tests. I heard yesterday that he has
renal failure. I took a urine specimen in today and I have another
appointment to discuss next steps regarding treatment with my vet on Monday.

She said not to worry about diet with him at the moment, it's far more
important getting him eating so I'm giving chicken and tuna which is doing
the trick, but he's still only eating about one third of what he would
normally eat, but at least his weight has stabilized.

I've been surfing to see what the options are and it seems that drugs are an
option with a renal diet. Sounds fine except he has always been a finicky
eater and despite me trying just about every food on the market he eats only
one brand of dried food and even then only one of the flavours in that food.
Of course he will always eat fresh chicken and tuna for which I am grateful
for at the moment.

I know it is terminal so the question is not if he will die, but when. The
more I think about it the more I would prefer him to have a shorter happier
life eating what he likes than a longer miserable life having constant
battles with him over food. I will happily take the medication if that's
appropriate but I just know the diet is going to bring a lot of stress. I
was pretty horrified to read some people having to force feed their cats, I
could never do that to him. He's like my kid and I don't want him to suffer
just because I want him round just a little bit longer.

If anyone has been through this I would appreciate some thoughts?
