Changed purring is not a diagnosis
Cats Protection advises a vet check when a cat purrs much more, in different situations, or starts or stops unexpectedly. Such a change does not establish a cause by itself. This website does not decide whether a cat is ill, frightened or comfortable, and it gives no waiting interval.
Sound cannot rule out pain
Both Cats Protection and Blue Cross explain that cats may purr while in pain or unwell. A pleasant or familiar purr therefore cannot be used here as evidence that care is unnecessary. No audio pattern, text description or note output is a medical assessment. Contact your veterinary team about a concern.

No normal-purr calculator
Cats Protection notes that cats differ and some do not purr. This site provides no universal daily count, duration, loudness score or baseline that separates normal from abnormal. Do not stage listening sessions or wait for a threshold before seeking advice about a change that worries you.
You can ask before the note is complete
A useful question can be as short as this sounds different from usual. You do not need a recording or a polished card. The temporary note is optional and not sent to a clinician. Do not wait for an app response or editorial reply when an animal needs professional advice.
