The normal PCV range for cats is best described as which option?

• A. 33-45%
• B. 25-55%
• C. 20-40%
• D. 40-60%

Answer: (B)

The main concept is that PCV, or packed cell volume, is a percentage that reflects the proportion of red blood cells in the blood, and what’s considered “normal” is a range rather than a single value. In cats, healthy values can vary because of factors like age, breed, hydration, and the method used to measure. While many cats fall into the roughly mid-30s to mid-40s percent range, it's normal to see values a bit lower or higher in healthy individuals.

Choosing a broad range like 25 to 55 percent best describes this normal variability across different cats and laboratory references. It accommodates the natural fluctuations you might encounter in practice, whereas narrower ranges could exclude healthy cats or be less representative of real-world variation.
