Step 3: Schedule Blood Work for Days 3-5
Anemia peaks 3-5 days after ingestion. Even if your cat seems fine, delayed Heinz body anemia can be life-threatening.
その背後の科学
ニンニク（Allium sativum）にはアリインが含まれており、砕いたり噛んだりするとアリシンに変換されます。アリシンおよびその誘導体（アリルプロピルジスルフィド、アジョエンネ）はネコ科動物の赤血球中のヘモグロビンを酸化変性させます。ネコ科動物のヘモグロビン分子は8-10個のスヒドリル基を持ち（犬は2-4個）、酸化損傷に対して2-3倍感受性が高いです。結果として生じるハインド体は脾臓のマクロファ貪食され、血管外溶血を引き起こします。タマネギと異なり、ニンニクのチオ硫酸塩は肝代謝の違いにより猫においてより生物学的利用可能性が高いです（Merck Veterinary Manual、2023）。
よくある質問
Is garlic toxic to cats?
Yes, garlic is highly toxic to cats — approximately 5x more potent than onion per gram. Garlic (Allium sativum) contains allicin, alliin, and allyl propyl disulfide, which cause severe oxidative damage to feline red blood cells. Cats are uniquely susceptible due to the structure of their hemoglobin molecule.
How much garlic is toxic to cats?
As little as 5g of garlic per kg of body weight can cause toxicity. For a 4kg cat, this equals just 1 small clove (approximately 5g). Toxic effects can also occur from chronic low-dose exposure — even trace amounts in food or supplements over weeks can accumulate and cause anemia.
Is garlic salt/powder dangerous for cats?
Yes, garlic powder and salt are concentrated forms. As little as 1/8 teaspoon of garlic powder can be toxic to a small cat. Dry garlic powder, garlic supplements, garlic-flavored treats, and garlic-infused oils all pose risks. Many human foods contain hidden garlic — always check labels.
What are the symptoms of garlic poisoning in cats?
Symptoms develop 1-5 days after ingestion: pale gums (anemia), lethargy, weakness, rapid breathing, elevated heart rate, jaundice (yellow gums/eyes), reddish-brown urine, vomiting, and collapse. Heinz body anemia is confirmed by blood smear. Severe cases require blood transfusions.
