These responses can manifest as trembling or jerking of the head or extremities. In severe cases, the responses may appear similar to seizures.
Castor bean (Ricinus Communis) contains ricin which can cause multiple organ failure. It is most highly concentrated in the seeds but the seed coating must be damaged to release this toxin therefore, if seeds are swallowed whole, they may pass through the digestive system and not harm the animal.

Rhubarb (Rheum rhabarbarum) can cause tremors and kidney failure in cats and dogs. It contains soluble oxalate salts which are absorbed from the gastrointestinal tract and then bind with body’s calcium, resulting in a sudden drop in calcium. Rarely, acute renal failure can be seen from ingestion of plants or fruit containing these soluble oxalate crystals. Clinical signs of this type of poisoning include drooling, lack of appetite, vomiting, diarrhoea, lethargy, weakness, tremors, bloody urine and changes in thirst and urination in cats and dogs.
Sago palm plant (Cycas revolute) can cause diarrhoea, vomiting and seizures in cats and dogs and liver failure in dogs.
Salt. Unlike humans animals, such as dogs, do not sweat through their skin which expels excess salt so it builds up in their blood stream and can cause serious kidney and joint problems. Salted snacks, such as crisps and peanuts, are especially bad for their health and are high in calories which can also lead to obesity.
Shamrock (Oxalis triangularis) also known as sorrel, contains soluble oxalate salts which are absorbed from the gastrointestinal tract and then bind with body’s calcium, resulting in a sudden drop in calcium. Rarely, acute renal failure can be seen from ingestion of plants or fruit containing these soluble oxalate crystals. Clinical signs of this type of poisoning include drooling, lack of appetite, vomiting, diarrhoea, lethargy, weakness, tremors, bloody urine and changes in thirst and urination in cats and dogs. Fortunately shamrock tastes bitter so is rarely consumed in quantities large enough to cause any serious damage.
Star fruit. When soluble oxalate salts from these fruits are absorbed from the gastrointestinal tract, they bind with body’s calcium, resulting in a sudden drop in calcium. Rarely, acute renal failure can be seen from ingestion of plants or fruit containing these soluble oxalate crystals.
