Measure your cat's neck circumference and chest girth (the widest part behind the front legs) with a soft tape, then compare both numbers to the actual size chart on the listing — cat sizing varies more by body shape than weight, so a generic small/medium/large label isn't reliable. A snug but not tight fit keeps a sweater or harness from slipping off or rubbing.
What to measure
- Neck: Wrap the tape where a collar would sit, adding about half an inch for comfort.
- Chest girth: Measure around the widest part of the ribcage, just behind the front legs — this is the number that determines fit most for sweaters and harnesses.
- Length: For sweaters, measure from the base of the neck to the base of the tail.
Why it matters more for harnesses
A poorly fitted harness can let a cat back out of it during a startle response, or rub uncomfortably at the armpits if it's too tight. Getting the chest girth right is the single most important measurement for harness safety.
