百合對貓有毒嗎?

真百合(Lilium 與 Hemerocallis) · 由 Meowledge 撰寫 · 最後更新於

劇毒

是——劇毒,連花粉或花瓶水都足以致命。

貓咪接觸到真百合怎麼辦?

任何接觸都當作即時急症,包括舔到毛上的花粉或喝了一口花瓶水。請立即前往獸醫;途中可先致電獸醫或動物醫院急診。任何接觸後及早治療最關鍵,不要等症狀出現。

是。真百合(百合屬 Lilium 與萱草屬 Hemerocallis)對貓劇毒:全株都有毒,連花粉與花瓶裡的水都能造成腎衰竭,任何份量都當作急症,立即看獸醫。

百合有毒的部位

  • 葉
  • 莖
  • 花
  • 花粉
  • 花瓶水
  • 根莖(根)
「百合屬(Lilium)百合的所有部位對貓都有毒。」(本站翻譯)— Pet Poison Helpline

真百合中毒的症狀

  • 數小時內嘔吐、流口水、拒絕進食
  • 精神不振、虛弱
  • 初期尿量增加,之後尿量減少或無尿
  • 腎損傷形成後出現脫水
  • 若未治療,數日內惡化為腎衰竭並死亡

哪些百合對貓有毒?

名字叫百合的植物很多,但只有真百合會造成腎衰竭:百合屬(Lilium)與萱草屬(Hemerocallis)。Merck 列出復活節百合、亞洲百合、東方百合、觀星百合、老虎百合,以及萱草;其餘都不算真百合。

百合真百合?對貓的風險
復活節、亞洲、東方、觀星、老虎百合是(Lilium)腎衰竭
林地百合是(Lilium)腎衰竭
萱草(金針花)是(Hemerocallis)腎衰竭
鈴蘭否心跳異常
白鶴芋否口腔與腸胃刺激

不確定貓碰到的是哪一種?FDA 建議用手機替植物拍張照,獸醫就能判斷它是不是高毒性的那幾種。

馬蹄蓮等其他「百合」對貓有毒嗎?

有,但原因不同。馬蹄蓮與白鶴芋含不溶性草酸鈣結晶;貓咀嚼時結晶釋出,直接刺激口腔、舌頭、喉嚨與食道。這些症狀通常會自行緩解,而且它們不會造成真百合那種腎衰竭。

不是真百合,不等於安全。Merck 把這些「假百合」逐一列出——馬蹄蓮、白鶴芋、秘魯百合、劍蘭、百子蓮、睡蓮都在名單上;秘魯百合更容易被誤認成小一號的真百合,但只造成輕微腸胃不適。孤挺花在有毒植物清單上有自己的一列。

花粉與花瓶水危險嗎?

危險。FDA 說,貓理毛時舔掉毛上的幾粒花粉,或喝下花瓶裡的水,都可能發生致命的腎衰竭。International Cat Care 也提醒,即使是最小的份量也算數。

Pet Poison Helpline 同樣把葉、莖、花與根莖算進去。吃下任何一種,都可能帶來嘔吐、腹痛、脫水與腎衰竭。

為什麼百合對貓有毒?

沒有人知道確切原因。毒素尚未被鑑定出來,而 FDA 說它只影響貓,狗吃了頂多腸胃不適;可以確定的是它傷害腎臟,沒有治療就會走向急性腎衰竭。

Merck 把這個病叫百合中毒(lily toxicosis)。吃下後 1–3 小時可能流口水、拒絕進食、精神不振與嘔吐;接下來 12–30 小時尿量增加、脫水,嘔吐可能持續,International Cat Care 也列出虛弱。FDA 給的第一批症狀窗口更寬:0 至 12 小時;腎臟症狀則是 12 至 24 小時。

貓吃了百合但看起來沒事,還算急症嗎?

算。Pet Poison Helpline 說任何接觸後及早治療最關鍵:Merck 說及早治療、只有輕微症狀時預後極佳;等到貓幾乎不排尿才開始治療,預後轉為保守至不佳。

FDA 把等待的代價寫成數字:治療延後 18 小時或以上,腎衰竭通常已不可逆。任何份量的規則把百合與葡萄、葡萄乾放在同一類——沒有門檻,先打電話。

獸醫會怎麼治療?

靜脈輸液 48–72 小時,目的是保護腎臟。及早治療、只有輕微症狀時預後極佳;等到寡尿或無尿才開始,預後轉為保守至不佳。

Merck 建議輸液速度為維持量的 2–3 倍;寡尿之後是無尿,那是治療最不想見到的方向。沒有治療,死亡可能在 3–7 天內發生。

貓碰不到,可以養百合嗎?

不可以。International Cat Care 說家裡有貓,就絕對不要讓百合進入家中或花園;FDA 也認為最好不要把它們帶回家,因為光是花粉與花瓶水就足以致病。

百合常見於花束與插花,收到花之前先檢查一次。本頁每一句都對應一段引文,方法寫在研究方法。

  5. 5.FDA — Lovely Lilies and Curious Cats: A Dangerous Combination

    顯示引述的原文與中譯
    原文(FDA)「While their flowers are lovely to see and smell, lilies pose a significant safety threat for your cat... Lilies in the “true lily” and “daylily” families are very dangerous for cats... licking a few pollen grains off its fur while grooming, or drinking the water from the vase can cause your cat to develop fatal kidney failure... The toxin, which only affects cats, has not been identified. Dogs that eat lilies may have minor stomach upset but they don’t develop kidney failure... Early signs of lily toxicity in cats include decreased activity level, drooling, vomiting, and loss of appetite. These symptoms start 0 to 12 hours after ingestion... Signs of kidney damage start about 12 to 24 hours after ingestion and include increased urination and dehydration... Kidney failure occurs within 24 to 72 hours, leading to death if the cat isn’t treated... if treatment is delayed by 18 hours or more after ingestion, the cat will generally have irreversible kidney failure... Wood lily... Lilium philadelphicum or umbellatum... it’s best to not bring these plants into your home if you have a cat... Other plants may have the word “lily” in their name but they aren’t in the “true lily” or “daylily” families and don’t cause kidney failure in cats... Lily-of-the-valley contains toxins that cause the heart to beat abnormally. This abnormal heart rhythm can be life-threatening... Both calla lilies and peace lilies contain insoluble crystals of calcium oxalates... the crystals are released and directly irritate the mouth, tongue, throat, and esophagus... The signs usually go away on their own... The Peruvian lily contains a toxin that causes mild stomach upset (vomiting and diarrhea) if a cat or dog ingests a large amount... The Peruvian lily can be mistaken for a smaller version of a “true lily” plant but doesn’t cause kidney failure in cats... If you suspect that your cat has eaten any part of a lily or its pollen or has drunk water from a vase containing lilies, immediately call your veterinarian or a pet poison control center... take a picture of it on your cell phone... determine if it’s one of the highly toxic ones」
