Aloha! You're speaking with Dr. Michael Salkin
I'm sorry to hear of this with Lucy. Her anorexia, weight loss, and increased volume of urine (polydipsia) suggest chronic renal insufficiency in the great majority of our 14 year old cats. She has to be polydipsic (increased thirst) as well if she's forming so much urine.

Chronic hepatic insufficiency can also cause those symptoms.

Lucy's vet will want to perform a thorough physical exam and a senior/geriatric diagnostic panel of blood/urine tests to clarify just what's going on. Lucy's tests referable to her kidneys - the serum BUN, creatinine, and phosphorus as well as her urine specific gravity - need to be carefully evaluated because they will tell you whether Lucy will respond to therapy satisfactorily. Therapy for chronic renal insufficiency involves supplemental fluid adminsitration - either subcutaneously or intravenously depending upon the severity of her failure - dietary restrictions and supplements.

Please respond with further questions or concerns if you wish.
