Educational information, not veterinary advice. A new or concerning change deserves veterinary advice even if an estimated sleep total looks ordinary. Do not wake, handle or keep a cat active to complete a record.
Rest and sleep
A quiet posture is something an owner may observe. A sleep stage is not established by the website or a worksheet. Cats Protection describes both resting and sleeping intermittently; this reference does not pretend the two can always be separated from a glance.
Baseline
A baseline here means the pattern you believe is usual for that cat. It is not a medical reference interval. It may be incomplete or unknown, especially after adoption or a change in household routine. Do not fill it with a population average.
Unobserved interval
A period when nobody saw what happened is unobserved. It is not confirmed sleep, confirmed activity or proof that nothing changed. Our tools preserve the gap rather than manufacturing a daily total.
Change and interpretation
Change describes a difference from what was usual or expected. Interpretation proposes a reason. International Cat Care recommends veterinary advice for concerning changes; the worksheet cannot decide the cause or replace that advice.
