How to Measure Your Cat's Ribcage Circumference
How to Measure Your Cat’s Ribcage Circumference
Equipment needed: Flexible measuring tape (tailor’s tape works best)
Steps:
- Position your cat – Ensure your cat is standing upright with their head in a natural position. Your cat should be calm and comfortable.
- Locate the 9th rib – Find the area just behind your cat’s front legs. This is where the 9th rib is located, which is the standard measurement point.
- Wrap the measuring tape – Place the measuring tape around your cat’s ribcage at this 9th rib level, wrapping it completely around their body. The tape should be snug but not tight – you should be able to slide a finger underneath.
Record the measurement – Note the circumference in centimeters where the tape meets.
