Four years ago my then 16 yr old kitty was in kidney failure.My vet had me subcutaneously inject him with 150 mgs of ringers solution every other day and even though he has slowed down quite a bit he's still a great pet.I recently had the vet do a blood chemistery profile and he now has an electrolyte imbalance,his sodium and chloride is very high.Has anyone had a cat with a similar problem,and if so how was it treated ?
