For this reason, it is important to provide your veterinarian with as much information as possible. They will look at the clinical signs and previous diseases. When a cat which is not especially muscular has increase in creatinine, it is possible to suspect a prerenal, renal or postrenal cause after an exhaustive anamnesis (medical history). A sample will be taken after checking the cat's muscle status through a physical examination.

Many of the symptoms of high creatinine levels can be related to other diseases or health conditions. Frequency (urination in small amounts several times a day).Strangury (painful drop-by-drop urination).When creatinine increases because it cannot be eliminated, signs of f eline lower urinary tract disease (FLUTD) occur, as one of these diseases that compose it is the cause, such as the following: Kidneys enlarged in acute disease or reduced in size in chronic disease.Polyuria (increased volume of urine) and polydipsia (increased thirst) in chronic cases.Oliguria (reduced urine volume) or anuria (not urinating) in acute cases.In the case of damage to the glomerular filtration due to kidney disease, signs of kidney disease may appear, such as: Changes in heart rate and breaths per minute.Higher skinfold compressibility due to dehydration.

Dryness and paleness of the mucous membranes.it affects the passage of fluid through the kidneys), it is common for symptoms related to reduced blood flow such as: For example, when high creatinine is secondary to a renal perfusion disorder (i.e. However, when they are due to an underlying disease or health disorder, the effects on their body can be serious. When the high levels of creatinine are due to large muscle mass, it is unlikely the cat will show any particular symptoms. Learn more about various types of urinary problems in cats with our article on feline lower urinary tract disease. These include obstruction of the urethra or ureters, ligation of the ureter, leakage or rupture of the urinary bladder. Rather, creatinine cannot leave the cat's body as the flow of urine is blocked for various reasons. Increased post-renal creatinine: in this case, the increase in creatinine is not due to a poor glomerular filtration rate.The damage in this case can be due to poisoning, hypophosphatemia, hypercalcemia, infarcts, thrombosis, infections, polycythemia, pyelonephritis, urinary tract infections, non-steroidal anti-inflammatory drugs, hypertension or hypovolemia, among others. Consequently, its filtration rate decreases and creatinine increases. Increased renal creatinine: occurs when damage to the kidney caused by an alteration, damage or disease produces a loss of its function.Creatinine in this case increases at a slower rate than urea, since it is not subsequently reabsorbed. This is due to alteration of its blood flow due to different causes such as dehydration, altered cardiac output, hypovolemia or a marked vasodilation. Increased prerenal creatinine: the reduction in glomerular filtration and the consequent increase in creatinine occurs when renal perfusion decreases.Increased creatinine levels in a cats blood can be of three types:
