Hiding for long periods, markedly less social interaction, becoming quiet — what could it be, and what should I record?

Common in cats (one of the most common ways pain shows itself; owners often misread it as "getting old, personality has changed"), dogs and rabbits. The direction is a veterinary visit needed (a cat "going quiet" cannot be treated as a mere personality change; rule out pain and disease first). What you can record at home: how often and at what times the hiding happens, and whether appetite and toileting change at the same time. This is a triage index; the actual judgement still rests with a veterinarian on a case-by-case basis, and this text gives no drug names or dosages.

Over-grooming, feather plucking, or grooming only one spot until hair loss or skin damage — what could it be, and what should I record?

Common in cats (over-grooming is common with stress or with pain at that site), birds (feather plucking and self-mutilation) and rabbits. The direction is a veterinary visit needed (rule out pain or skin disease at that site first; a veterinary examination must come before behavioural training). What you can record at home: whether the over-groomed site is always the same, and whether there are other sources of stress (a new household member, a change of environment). This is a triage index; the actual judgement still rests with a veterinarian on a case-by-case basis, and this text gives no drug names or dosages.

A normally gentle animal suddenly starts growling, baring teeth or attacking — what could it be, and what should I record?

Common in both dogs and cats. The direction is a veterinary visit needed to emergency (never punish a growl — it is the last warning the animal gives you, and punishing it is like removing the alarm). What you can record at home: the trigger (which body part was touched, when it happened) and whether earlier stress signals such as freezing, lip-licking or head-turning were missed. This is a triage index; the actual judgement still rests with a veterinarian on a case-by-case basis, and this text gives no drug names or dosages.

This record notes the source location and content hash of "Symptom Triage｜Behavioural Change", 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 "Symptom Triage｜Behavioural Change | Evidence chain": the section beginning at line 107 of `30-索引-症狀鑑別.md` in the veterinary encyclopaedia. The SHA-256 of that section (first 16 characters) is `59b8a06eda797338`, which anyone can recompute to confirm the content has not been altered.

Anchor granularity

This chapter has no entries at all in the project’s row-level anchor file `planning-out/anchor-436.tsv` (its 490 anchors cover eight chapters: dogs, cats, fish and aquarium, reptiles and amphibians, birds, backyard poultry, farm animals and horses, and wildlife). What can therefore be verified here is only the chapter-level content hash listed above, with no per-row claim ids — the same level as this site’s existing chapter overview and index articles.
