My almost-19 year old cat is in renal failure and her creatinine levels are very high. She is extremely constipated, dehydrated, weak, knuckling, and will eat only upon prompting. She is 4 pounds. She started urinating near her water dish. We have been giving her sub-Q 2x a week at 100mL per dose. We took her to the emergency vet who kept her throughout the day, gave her sub-Q and two enemas. The enemas did not work. The vet sent her home and told us to increase her sub-Q to 200mL, administered twice a day for a total of 400mL/day in an emergent effort to rehydrate her and to get her to have a BM. We are using Lactated Ringers. Vet said this is a last-ditch effort to bring her creatinine levels down. Our cat is very sick. Is this too much fluid?
