Symptoms of Kidney Disease in Cats

By Juniper

Instructions

Increased Thirst and Urination

Step 1:
Increased thirst is usually the first symptom of an infection of the bladder, kidneys or urethra. This is usually followed by increased urination, but the cat may be unable to urinate, depending on the severity of the disease.

Bloody Urine

Step 1:
Blood in a cat's urine may be caused by cystitis (an infection of the bladder) rather than kidney failure. However, cystitis can quickly spread to the kidneys or cause a blockage, especially in male cats.

Sudden Weight Change

Step 1:
A cat with kidney disease may suddenly lose weight due to dehydration, or suddenly gain it because of excess fluid retention.

Urinating in Unusual Places

Step 1:
Cats with kidney disease or cystitis often urinate outside the litter box to communicate their discomfort, or because they have lost continence due to the infection.

Vomiting and Diarrhea

Step 1:
Due to buildup of toxins and fluid, a cat with kidney failure may have foul-smelling, very aqueous, or bloody vomit and diarrhea. Other cats become severely constipated due to dehydration.
