Dangerous Plants
Some plants, while not necessarily deadly, still pose a danger to your rabbit if she ingests them. Immediate veterinary care can usually reverse danger signs, but it's still crucial to keep your rabbit away from these plants at all times.
Aroid Family
(anthurium, arrowhead vine, ceriman, Chinese evergreen, cut-leaf philodendron, devil's ivy, dieffenbachia, dumb cane, elephant ears, green dragon, jack-in-the-pulpit, Mexican breadfruit, nepthytis, philodendron, pothos, skunk cabbage, taro, tri-leaf wonder)
* Toxicity Rating: Moderate. Pets may sample these commonly available plants with a nibble or two, but rarely ingest enough to cause serious problems or death. Risk increases if hungry or bored rabbits are housed near these plants.
* Dangerous Parts of Plant: Roots, leaves and stems.
* Symptoms: Mouth and throat irritation, salivation and, rarely, stomach irritation and diarrhea.
* Plant Description: All 2,000 species of this family of plants should be treated as potentially toxic. A few, such as taro (poi), are eaten after cooking eliminates the poison. Seven species of aroids occur naturally in wet areas. Jack-in-the-pulpit and skunk cabbage are the most common and best known of these. Dumb cane, pothos and philodendron are potted plants found in offices, restaurants and homes.
Aroids are perennials. Some are vines. The large net-veined leaves, which may have white or colored spots, are borne on leaf stalks that sheathe the stem. Most have simple leaves, but jack-in-the-pulpit has three-parted foliage. The aroid flower is a fleshy green, white or yellow spike borne inside a wraparound hood or bract (spathe). The fruits are brightly colored berries borne in tight clusters; they are not often produced by the house plant species.
* Signs: The plant cells contain needlelike crystals of insoluble calcium oxalate that penetrate the skin and mouth, causing discomfort. In addition, these plants contain proteolytic enzymes that release histamine and kinins, causing swelling and an itching or burning sensation. An affected rabbit will shake her head or paw or rub her face and mouth. She may salivate or foam at the mouth, seek water or have visible swelling. Severely affected rabbits may experience oral swelling to the point that swallowing and breathing become impaired. Typically, rabbits are not severely affected, since a few bites of an aroid plant often deter further consumption. Occasional reports of these plants causing kidney failure in rabbits exist but have not been verified. Effects in rabbits appear to be limited to the signs described above. Some of these plants have been used by humans to prevent individuals from talking by causing excessive tongue swelling; hence comes the name "dumb cane."
* First Aid: For minor irritation, provide supportive care and prevent further exposure. For more severe signs, if the rabbit does not improve within a few minutes or if swallowing or breathing is impaired, consult a veterinarian immediately.
* Prevention: Rabbits should not be allowed to consume these plants. Remove the dangerous plant from the rabbit's environment.
