Cat Chronic Renal Failure
Cat chronic renal failure is most common on older
cats and is very serious. The affects are irreversible and
happen over a period of months to years.
Kidneys are made up of tiny funnel shaped tubes called
nephrons. They both filter and reabsorb fluids in the cats
body creating a balance. If one of the nephrons is damage
and this can be done by age, poison and infection, it will
stop working. However the kidney is very efficient and can
continue to work efficiently with only 25% of the kidney in
good health. This is accomplished by the remaining nephrons
growing larger in order to fill the gaps.
Kidney failure happens as soon as the 25% functioning
nephrons break down and drop to below 25%. Without the
kidneys to clean the blood of toxins, such as urea and
creatinie creat problems by building up rather than being
Diagnosing Chronic Renal Failure
Chronic renal failure can be diagnosed by a blood panel
test that measures the levels of important parts of the
blood. Parts such as blood urea nitrogen, red blood cell
count and creatinine are measured for normality. A urine
sample will also be taken for analysis to check that levels
of protein, bacteria and blood are as they should be.
