猫のNot eating — どうすればいい?
Over 24 hours without food puts a cat at risk of fatty liver disease; over 2 days is a must-see.
よくある原因は?
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 infectious peritonitis (FIP)
救急 — すぐに受診Caused by a mutated coronavirus; young and stressed cats are prone — the wet form shows a swollen belly.
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.
Stomatitis / severe periodontal disease
24 時間以内に受診Severe oral inflammation makes cats refuse food, drool and paw at the mouth — needs professional dental care.
Feline pyometra (uterine infection)
救急 — すぐに受診A post-heat emergency of unspayed females, often better hidden than in dogs (cats lick away discharge). Thirst + lethargy + a changing belly deserves high suspicion; surgery is the cure.
Upper respiratory infection (cat flu)
48 時間は様子見Mostly herpes/calicivirus; kittens and unvaccinated cats are at risk — a blocked nose leads to refusing food.
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.
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.
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.
Stress / anxiety-related behavior problems
自宅で観察Moving, new pets or visitors can trigger hiding, soiling and over-grooming — but rule out medical causes first.

よくある質問
猫のNot eating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。Hepatic lipidosis (fatty liver), Feline infectious peritonitis (FIP), Linear foreign body / intestinal obstruction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。
