What is most easily got wrong when feeding a hedgehog?

Omnivorous (staple of insects/good-quality cat food or a dedicated hedgehog diet), with insects added in moderation as an activity incentive. Common feeding errors: chronic overfeeding leading to obesity (hedgehogs put on weight very easily, which affects mobility and organ health), and an inappropriate fat proportion in the diet.

ハリネズミの給餌で最も間違えやすいのは何ですか。 — 雑食性（主食は昆虫/良質なキャットフードまたはハリネズミ専用フード）で、活動の動機づけとして昆虫を適量補います。よくある給餌の誤り：長期の過剰給餌による肥満（ハリネズミは非常に太りやすく、運動と内臓の健康に影響します）、フードの脂質比率が不適切。

What signs in a hedgehog mean going to a veterinarian straight away?

Staying curled and completely failing to unroll for an abnormally long time, marked worsening of an unsteady gait, an ambient temperature so low that dangerous pseudo-hibernation is suspected (cold to the touch and slow to respond), refusing food for more than a day (the exact threshold 【No single authoritative figure for this item: the whitelisted sources do not provide a reference value for a small-mammal-specific anorexia time threshold; this belongs to case-by-case clinical judgement and individual variation is wide — do not wait against this number, verified 2026-07-30】; in small mammals anorexia is in itself a reason to seek care, and the sooner the better).

ハリネズミにどんな状態が現れたらすぐに受診すべきですか。 — 丸まったまま異常に長く全く開かない、歩様のふらつきが明らかに悪化、環境温度が低すぎて危険な擬似冬眠状態に入った疑い（触ると冷たく反応が鈍い）、1 日以上の拒食（正確な閾値【この項目に単一の権威ある数値はありません：ホワイトリストの出典は 小型哺乳類 に固有の 拒食時間の閾値 の参考値を示していません。これは症例ごとの臨床判断の範疇であり、個体差も大きいため——この数字を基準に待たないでください、確認2026-07-30】；小型哺乳類では拒食そのものが受診の理由であり、早いほどよい）。

What is the most common disease in hedgehogs?

1. Wobbly Hedgehog Syndrome (WHS): a neurodegenerative disease of unknown cause (a hereditary basis is suspected; mechanism: Merck Vet Manual: 「The etiology of WHS remains unknown, but a hereditary basis is suspected.」 the pathology is described as 「spongy myelinopathy」, with bilaterally symmetrical spongy lesions at multiple sites in the central nervous system (cerebellum, medulla, spinal cord); <https://www.merckvetmanual.com/exotic-and-laboratory-animals/hedgehogs/diseases-of-hedgehogs>; the AEMV care guide describes it only briefly as 「progressive demyelinating paralysis」 without an aetiology, verified 2026-07-30) → progressive hindlimb weakness, wobbling gait, gradual paralysis → neurological examination (to exclude other causes) → no cure at present, supportive care only (prescription) → no known effective prevention.
