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.
The source's broad observation
Cats Protection says kittens and senior cats are likely to sleep more than average adult cats, relating this to growth or tiring more readily. This is general information, not an age-specific hour prescription or an assessment of an individual animal.
Avoid the just-getting-older shortcut
Knowing a cat is older does not establish why its routine changed. International Cat Care emphasizes that medical causes should be considered when behavior changes. Keep a veterinary question open rather than assigning age as the answer.
A recently adopted cat has missing history
You may not know what was usual before adoption. Unknown baseline is a valid entry, not a reason to invent one or wait until a pattern is documented. A veterinary team can advise even when records are incomplete.
Keep comparable observations modest
A quiet weekday and a busy visitor day are different contexts. Write those differences down if useful, without treating them as controlled comparisons. This is not a sleep experiment, an aging score or a test of whether the cat is healthy.
