Have Cat Questions? Ask a Cat Vet Online.
Such profound weight loss is seen with malignancies and the end stage of many different metabolic diseases - chronic renal failure as you mentioned, chronic hepatic failure, and diabetes mellitus are just a few of the common ones at her age. Unfortunately, we don't have the luxury of waiting to have her vet take a look at her because your description of her is one of a critically ill severely dehydrated and electrolyte-imbalanced cat. I understand your financial constraints, however. You are looking at a significant expense for a cat whom needs to be hospitalized for critical care while diagnostic results are pending and Chloe's prognosis for meaningful recovery must necessary be poor whatever is finally diagnosed. I regret to say that under the circumstances, euthanasia would be an reasonable course of action.
Please respond with further questions or concerns if you wish.
I understand. I can't set a follow-up in this venue and so would appreciate your returning to our conversation with an update - even after rating - at a time of your choosing.
