FAQ

What is the most easily overlooked problem in multi-cat households?

Stress from resource competition, which can trigger feline idiopathic cystitis and urine spraying, on top of covert bullying and the difficulty of monitoring each cat's body weight and food intake. The approach is to provide separate resources per cat (food, water, litter, high perches, resting spots), set the number of litter boxes at the number of cats plus one, and introduce new or newly arriving cats only after a full quarantine period.

多頭飼い家庭で最も見落とされやすい問題は何ですか？ — 資源をめぐる競争によるストレスです。猫特発性膀胱炎やスプレー行動を誘発し、見えにくいいじめや、個体ごとの体重・食事量を監視しにくい問題も重なります。対策は、猫ごと・資源ごとの分離配置（食事、水、トイレ、高い場所、休息場所）、トイレの数は猫の数＋1、新入り猫や新たに同居する猫は完全な隔離期間の後に紹介することです。

Does a cat that stays indoors need no parasite control?

It still needs it — this is exactly the most common mistake among indoor-cat owners, because flea eggs can be carried in by people. The key prevention for indoor cats is environmental enrichment and hunting-style feeding, window screens and fall-prevention nets, keeping toxins and strings out of reach, and the number and cleanliness of litter boxes.

猫が外に出ないなら駆虫は不要ですか？ — いいえ。それこそが室内飼いの飼い主に最も多い間違いです——ノミの卵は人が持ち込むことがあります。室内飼い猫の予防の要点は、環境エンリッチメントと狩りを模した給餌、網戸と転落防止ネット、毒物とひも類の片付け、トイレの数と清潔さです。

Does a pedigree certificate mean a purebred cat is healthy?

No. "Having a pedigree = healthy" and skipping genetic tests is exactly the most common mistake purebred-cat owners make. Before buying or adopting, check the breed's genetic-test reports; brachycephalic breeds should avoid heat and strenuous exercise; fold-eared and other breeds at high risk of bone and joint disease need long-term pain assessment; and health checks should add breed-matched echocardiography, kidney ultrasound, and ophthalmology items.

血統書のある純血種の猫は健康だと言えますか？ — いいえ。「血統書がある＝健康」と考えて遺伝子検査を省くのが、純血種の飼い主が最も犯しやすい間違いです。購入や譲渡の前にその品種の遺伝子検査報告を確認し、短頭種は高温と激しい運動を避け、折れ耳など骨関節疾患リスクの高い品種は長期的な疼痛評価が必要です。健診でも品種に対応した心エコー、腎エコー、眼科の項目を追加してください。
