What level of BUN indicates kidney failure in cats?

I'm worried because my cat's recent bloodwork showed an elevated BUN level. The vet mentioned that this is related to his kidney function, but I forgot to ask what level would indicate something as serious as kidney failure. Can you help me understand what BUN level I should be concerned about and whether there are other signs I should watch for?

Answer

Your cat's recent bloodwork shows an elevated BUN level, indicating potential concerns with kidney function. Understanding the significance of BUN levels will help you monitor your cat's health effectively.

  • Elevated BUN levels can indicate issues, but context is key
  • Look for other signs of kidney problems
  • Consult with a vet for a comprehensive assessment

BUN, or Blood Urea Nitrogen, is a waste product filtered by the kidneys. Elevated levels can indicate reduced kidney function, but it's essential to look at the complete picture, including creatinine levels and urinalysis results. BUN levels themselves don't diagnose kidney failure but typically a significant increase alongside other abnormal values warrants closer attention. It's important to monitor for symptoms like increased thirst, frequent urination, vomiting, weight loss, and lethargy, which may accompany kidney concerns.
