Pet Hematuria Symptom Guide | Observation Points and When to Seek Care
Understand possible causes of Hematuria and key points for home observation
Blood in the urine suggests possible urinary tract bleeding or inflammation. Closely observe urine color, frequency, and the urination process, and record changes for evaluation.
What this symptom means clinically
Hematuria is the presence of blood or red blood cells in urine, reflecting rupture or leakage from the mucosa or blood vessels of the urinary tract, including kidneys, ureters, bladder, or urethra. Bleeding may result from local erosion, inflammation, stone abrasion, or fragile vessels, causing urine color to range from pink to dark red. Clinically, hematuria can help indicate whether lower or upper urinary tract disease is involved and where bleeding may originate.
🐱 In cats
In cats, hematuria is often associated with cystitis, urethral obstruction, or lower urinary tract disease. Male cats have a narrower urethra and are more prone to obstruction with hematuria.
🐶 In dogs
In dogs, hematuria may be related to stones, cystitis, bladder tumors, or trauma. Common causes vary by breed and age.
