It would be at the high end of normal if that is the reference range used by the lab. I'm just guessing as to the lab reference range. At other labs the 2.4/2.5 would be considered high, but not in the end stage of renal failure, more like the second stage of CRF. That is why it is vital to have these for the specific lab used.
So...that brings me to my next questions:
Besides his Creatinine, what was his BUN (blood urea nitrogen), Specific Gravity (urine), Ca (calcium), P (phosphorus), K (potassium), Na (sodium), and any other values you can get out of your vet. He should furnish these records--just request them and don't quit requesting them until the vet gives them to you.
Oh man, that is just absurd thinking on your vet's part about the fluids. You won't be doing a long drawn out process (around 5 minutes to administer the fluids!), you will do sub-Q fluids where the needle is inserted under the skin, not IV drip where it needs to be in a vein. It would be more stressful to have Darwin hooked up to a needle, etc. in a small cage for days on end when all he needs is a small amount of fluid (50-75mL) given once a day or every other day. Plus, how the heck would the needle stay in for that extended amount of time--my kitties would be bouncing off the walls of any cage! Honestly, I think you need to find a different vet. Your vet sounds utterly clueless when it comes to giving CRF kitties sub-Q fluids.
You need "ringer lactated" (Lactated Ringers Solution [LRS]), not sodium chloride because sodium chloride burns. Here's a link to different common sub-Q fluids. You want LRS because for one thing, that is closer in pH to what a kitty's body pH is. The sodium one, besides burning, has a very low pH--which you don't want.
Here's a video on how to administer sub-Q fluids demonstrated by a vet (one thing I should mention that he didn't is that you should always use a NEW sterile needle each time--never re-use a needle):
That being said, if you can add extra water to Darwin's food (and daily keep track of how much--you would have a log of how much for every day and how much each time by the end of that day) and/or use a dropper or needle-less syringe and syringe water by mouth (again, keep track of how much), you may not need to do the sub-Q fluids. You could aim for 5-10mL (cc's) per pound of Darwin's weight per day. Just add to his food and/or dropper/syringe by mouth that amount per day. Say he weighs 10 pounds, if you did 5mL per pound that would be 50mL per day. If doing 10mL it would be 100mL per day. You just spread it out the daily amount by adding to his food and by mouth with the syringe. Hope that made sense. If not, let me know and I'll try to explain it better.
I've got to say that my Tuffy hated getting sub-Q fluids, so on those days when he wasn't cooperating, I mixed extra water into his canned food, and if that wasn't enough I syringed water at the back side (between his back teeth on one side) of his mouth in small amounts--if I was going to give him 20mL/cc's I would do about 5mL at a time to make sure he didn't choke. I ended up doing it this way 90% of the time because it just wasn't worth the battle and stress that took place for my little guy giving sub-Q's.
Hang in there, sweetie, we're here to help!
