Adam and Eve Poisoning in Cats

The Adam and Eve plant is rather bitter in taste and causes immediate irritation, so high levels of consumption are rare. However, if the feline does consume more than a bite from the plant, episodes of severe diarrhea and vomiting soon follow the previous symptoms. As the feline’s body works to expel the toxin from the body through vomiting paired with diarrhea, the cat’s hydration levels drop severely, resulting in electrolyte imbalance and eventual shock. 

Adam and Eve is an herbaceous perennial plant that can be grown indoors and out. The Adam and Eve plant has many names including; the Cuckoo Plant, Bobbins, Starch Root, Wake Robin, Lord-and-Ladies, or Arum. This common household plant is highly toxic to felines as well as a large number of other mammals, causing potentially fatal symptoms. The majority of clinical signs a cat owner may note will present immediately or no later than two hours following ingestion. Clinical signs of Adam and Eve poisoning in cats include dry heaving, vomiting, gagging, pawing at the mouth, excessive drooling, head shaking and other signs of obvious irritation or pain. The feline may also vocalize, as the sap from the Adam and Eve plant cause needle-like pain to the tongue, mouth, and throat. 

A feline that has ingested any portion of the Adam and Eve plant will initially display clinical signs of intense irritation to the mouth. The feline may have difficulty swallowing (dysphagia), have a swollen throat demonstrated by choking sounds and excessive drooling as the plant sap inflames the mucous membranes. These initial symptoms of Adam and Eve poisoning may occur immediately after ingestion or up to two hours after consumption. If the feline can tolerate consuming larger amounts of the Adam and Even plant, symptoms become rather severe, resulting in rapid breathing (dyspnea), digestive upset (vomiting/diarrhea), renal failure, convulsions, coma and eventual death. A summarization of Adam and Eve poisoning symptoms in cats are listed below: 

• Dysphagia
• Chocking 
• Drooling 
• Dyspnea 
• Digestive upset 
• Renal failure 
• Convulsions 
• Coma 
• Death 

A feline can become poisoned by all parts of the Adam and Eve plant, including the leaves, petals, pollen and stem. What gives this plant its toxic nature is its special cells called idioblasts. These specialized cells differ from other cells because they are considered a non-living substance in the form of minerals, pigments, tannin, resin, gum, latex or oil. Raphides are the nonliving substance found in Adam and Eve plants, characterized by its bundles of needle-like crystals of calcium oxalate packed with gelatinous, oxalic acid. 

When a feline consumes a portion of the Adam and Eve plant, the idioblast cell is broken down by the cat’s saliva and allows the raphides’ calcium crystals to leave the cell. When the raphides leave the idioblast cell, they shoot out in violent, penetrating projections that pierce the feline’s mouth and embed themselves in the upper digestive tract. The feline feels immediate discomfort as the millions of microscopic needles lodges themselves in the mouth, tongue, throat and stomach. The idioblast cells continue to release raphides for up to two weeks after the feline first ingests the plant. 

The only true way to diagnose an Adam and Eve poisoning in cats is to see the cat consume the plant, however, this is usually not a possibility. Therefore, your veterinarian will perform a differential diagnosis to rule out other possibilities for why the feline is exhibiting the associated symptoms. The diagnostic process will begin with a physical examination, review of the feline’s medical history and a consultation with the pet owner. Following routine diagnostic procedures, the veterinarian will want to conduct a series of diagnostic tests that may include: 

• CBC (complete blood cell count 
• Biochemical profile (blood work) 
• Blood smear test 
• Urinalysis (examination of urine) 
• Fecal floatation test
• Fecal examination 
• Abdominal ultrasound and/or x-ray 

Although there is no known antidote to counteract an Adam and Eve poisoning in cats, immediate veterinary care can save the feline’s life. The veterinarian may administer medication to induce vomiting or give the feline an activated charcoal solution to bind with the toxic plant chemical, to later be passed in fecal form from the body. To further eliminate the Adam and Eve toxin, the veterinarian will likely start your cat on fluids given intravenously to replenish lost fluids and aid in the elimination of the toxin. Fluids will also slow down kidney failure, as the more fluids that are put into the feline’s body, the more fluids can be eliminated from the body. 

The prognosis for an Adam and Eve poisoning in cats is rather poor, as felines that survive often suffer from permanent kidney and liver damage. A positive prognosis can only be obtain from immediate veterinary attention.
