Sometimes you cannot see the blood till the urine is examined with a microscopic lense or spotted on urinalysis. Luckily, many cats experiencing blood in their urine have signs that resolve quickly with reasonably basic treatments. The two significant causes of blood in a feline’s urine are cystitis and feline lower urinary tract condition or FLUTD.

Symptoms of Hematuria in Cats

Symptoms of hematuria consist of blood in the urine, a check in itself. Red-tinged urine, with or without abnormal regular passage of urine will be evident. In patients with cancer, a mass may be palpated throughout the physical examination. Stomach pain will be evident in some clients.

Patients with a blood-clotting disorder may provide with subdermal skin hemorrhages, conditions called petechiae and ecchymoses, which appear as bruises. These discolored spots will be suggested by round, purple, non-raised spots on the skin.

What Causes Blood in Feline Urine

Appropriate treatment will depend on the results of these tests and the eventual diagnosis.

  • Systemic causes are typically due to coagulopathy (clotting).
  • Low variety of platelets or thrombocytes in the blood (a condition known as thrombocytopenia).
  • Diseases of the upper urinary tract are brought on by inflammation of the blood vessels (known as vasculitis).

Upper urinary tract — the kidneys and ureters:

  • Structural or anatomic disease, such as cystic kidney disease and familial kidney disease.
  • Metabolic diseases, such as kidney stones.
  • Neoplasia.
  • Infectious diseases.
  • Nephritis.
  • Idiopathic causes.
  • Injury.

In the lower urinary tract:

  • Infectious disease.
  • Inflammatory disease in the kidney.
  • Unknown cause.
  • Injury.

Lower Urinary Tract bladder and urethra:

  • Structural or structural concerns such as bladder malformations are implicated in bringing on hematuria.
  • Metabolic causes, such as stones, are possible.
  • Neoplasia.

Transmittable disease (such as bacterial, fungal, and viral disease):

  • Idiopathic causes.
  • Injury.
  • Chemotherapy can generate hematuria.
  • Unidentified cause.
  • Trauma.

Problems including the genitalia consist of metabolic conditions:

  • Heat cycle, or estrus.
  • Neoplasia.
  • Cancer or tumors.
  • Infectious disease such as from bacteria and fungi.

Ultrasonography, radiography, and contrast radiography might be useful in acquiring a medical diagnosis. If any mass lesions are suggested, a biopsy may be required for a definitive diagnosis. A vaginoscopy in female felines or a cystoscopy in male cats will rule out neoplasia and lower urinary tract issues.

How to Treat Blood in the Urine in Cats

Urinary tract infection might be related to another illness including the urinary tract, such as cancer, or urinary tract stones (urolithiasis). Or, hematuria might be brought on by a condition that involves the body in the primary, such as with an extreme production of steroids by the adrenal glands, or diabetes. A generalized systemic condition will require treatment before the hematuria can be resolved.

Surgery might indicate for cases with urinary tract stones, neoplasia, and distressing injuries to the urinary tract. Blood transfusions may be needed if your feline has a severely low red blood cell count. Fluids will be used to deal with dehydration, and antibiotics can be utilized to treat urinary tract infection and generalized diseases due to bacteria in the blood (bacteremia). Urolithiasis and kidney failure may need diet modification top to avoid relapse.

If your cat is struggling with a thickening condition, the blood thinner Heparin might be used to bring it under control.
