What should be noted about life-stage classification in cats?

The mature / senior age cut-offs follow the 2021 AAHA/AAFP Feline Life Stage Guidelines (catvets.com): Mature adult 7–10 years, Senior 10 years and above (verified 2026-07-30, cited as in column 1); ⚠️ the 2021 edition has been simplified to 4 stages plus an end-of-life stage, which does not map exactly onto the older naming used in this table. The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.

What should be noted about the typical "disease stacking" of the older cat?

Chronic kidney disease plus hyperthyroidism plus systemic hypertension plus osteoarthritis plus dental disease plus neoplasia plus cognitive dysfunction, often present at the same time and interfering with each other's treatment (for example, kidney disease only becomes apparent after the thyroid is treated). The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.

What should be noted about the presentation of feline cognitive dysfunction?

Night-time howling, getting lost in familiar surroundings, staring at walls, changes in social patterns, regression of litter-box habits, reversed sleep cycle. The actual judgement still rests with a veterinarian on a case-by-case basis, and this article gives no drug names or dosages.

This record notes the source location and content hash of "Cats | Old Age, Palliative Care and Euthanasia Decisions", so the text can be checked against the original.

How to use this record to verify

This record exists so that anyone can check for themselves whether the text has been altered. Every chapter of the veterinary encyclopaedia carries a starting line number and a content hash (the first 16 characters of its SHA-256). Recompute the hash over the original chapter: if it matches the value recorded below, what is published here is identical to the source chapter. The source list at the end is the authoritative material cited by that chapter — a chapter-level correspondence, meaning those sources underpin the chapter as a whole rather than mapping sentence by sentence. This is educational information and cannot replace a practising veterinarian; in an emergency, seek care immediately.

This record notes the source location of "Cats | Old Age, Palliative Care and Euthanasia Decisions | Evidence chain": the section beginning at line 376 of `21-T2-貓.md` in the veterinary encyclopaedia. The SHA-256 of that section (first 16 characters) is `7becfa0e92074c1a`, which anyone can recompute to confirm the content has not been altered.

This article covers the columns of the species’ 12-column knowledge tree other than the disease column; the disease column has been published as a separate article, so the two do not overlap.
