猫のVomiting — どうすればいい?
Occasional vomiting is common in cats (hairballs, eating too fast), but repeated or many-times-a-day vomiting needs attention.
よくある原因は?
Acute gastroenteritis
48 時間は様子見Fast food changes, diet indiscretion or mild infection; cats tolerate fasting poorly, so prevent dehydration.
Feline panleukopenia (feline distemper)
救急 — すぐに受診A severe viral disease of unvaccinated kittens with high mortality — needs isolation + intensive support.
Linear foreign body / intestinal obstruction
救急 — すぐに受診Cats love string, hair ties and thread — linear foreign bodies slice the intestine; a surgical emergency.
Hairball syndrome
48 時間は様子見Swallowed fur accumulates in the stomach — the occasional one is normal; frequent ones mean clearance is failing.
Urethral obstruction (blocked male cat)
救急 — すぐに受診Crystals or plugs block the narrow male urethra; fatal within 24-48 hours from rising potassium.
Poisoning (lilies / human medication / chemicals)
救急 — すぐに受診Lilies are lethal to cats; one acetaminophen tablet can kill; permethrin insecticide causes seizures.
Intestinal parasites
自宅で観察Roundworms, tapeworms, coccidia and more — common in kittens; regular deworming resolves it.
Hepatic lipidosis (fatty liver)
救急 — すぐに受診Just 2-3 days of anorexia can trigger fatty liver in cats; overweight cats are at higher risk — an emergency.
Feline vestibular syndrome
24 時間以内に受診A cat balance emergency: sudden head tilt, flicking eyes and stumbling. Idiopathic vestibular syndrome has an excellent prognosis (self-resolving in days to two weeks) — but otitis, toxins, tumors and clots must be ruled out.
Hyperthyroidism
24 時間以内に受診Common in senior cats — a revved-up metabolism: eating more yet losing weight, night yowling, fast heart rate.
Chronic kidney disease (CKD)
24 時間以内に受診The most common chronic disease of senior cats; early signs are subtle — blood creatinine + urinalysis stage it.
自宅での観察とケアのポイント
- ✓A short fast (no more than 12 hours), then small frequent meals
- ✓Provide several water stations
- ✓Log vomiting/diarrhea frequency and appearance
- ✓Isolate immediately
- ✓Do not give water by mouth (worsens vomiting)
- ✓Bring vaccination records and go now

よくある質問
猫のVomitingは重症?
症状の組み合わせ・継続期間・元気と食欲の状態によります。Feline panleukopenia (feline distemper), Linear foreign body / intestinal obstruction, Urethral obstruction (blocked male cat)など、早めの対応が必要な問題に現れることがある点に注意してください。 症状チェックで症状をすべて入力すると、より具体的な緊急度評価が得られます。
先に自宅で様子を見てもいい?何を見る?
元気・食欲が正常で他の症状がなければ、24〜48 時間の観察は妥当です。発生頻度、持続時間、食欲、飲水量、元気の程度、排泄物の見た目を記録しましょう。診察で非常に役立ちます。
受診前に準備するものは?
症状の開始時刻と変化を記録。誤食の疑いがあれば容器や残りを持参。ワクチン・駆虫の記録を持参。可能なら動画(歩き方の異常、咳の音など)を撮っておくと、口頭説明より伝わります。
