Button Battery Ingestion
Toxin
Potassium hydroxide, sodium hydroxide, cadmium, lithium, mercuric oxide, and zinc.
Source
Button-cell Battery
General Information
Ingestion of button-cell batteries can lead to esophageal erosions due to the release of potassium hydroxide or sodium hydroxide. Batteries in the stomach can cause gastric erosions and ulceration. These erosions may develop within 12 hours with the area in contact with the battery suffering the greatest damage.
Toxic Dose
Undetermined
Signs
Lack of appetite, vomiting, abdominal pain, and drooling.
Immediate Action
Seek veterinary attention.
Veterinary Care
General treatment: The button-cell battery may be removed with an endoscope. This allows for an exam of the esophagus and stomach at the same time. Abdominal surgery may need to be performed if endoscopy is unsuccessful at retrieving the battery.
Supportive treatment: Secondary conditions such as erosions or ulcers are treated with medications and dietary changes. The pet is monitored for symptoms of mercury or heavy metal poisoning and treated if necessary.
Specific treatment: Unavailable
Prognosis
Good, if the button-cell battery is removed immediately.

Borate
Toxin
Borate, Boric Acid, and Boron.
Source
Ant and roach baits, flea products, herbicides, fertilizers, denture cleaners, contact lens solutions, antiseptics, disinfectants, cleaning compounds, and mouthwash.
General Information
The mode of action of borate poisoning is unknown. It acts as an irritant which damages cells. The borates are concentrated in and cause the most damage in the kidneys.
Toxic Dose
Not determined for dog and cat.
Signs
Drooling, vomiting, abdominal pain, diarrhea, depression, ataxia, hyperesthesia, muscle weakness, tremors, seizures, blood in the urine, decreased urine production, coma, and death.
Immediate Action
Induce vomiting if ingested. Seek veterinary attention. If dermal exposure occurred, thoroughly wash the pet with warm soapy water. Dry thoroughly. Do not allow the pet to become chilled. Wear protective clothing/gloves to prevent human exposure.
Veterinary Care
General treatment: The induction of vomiting may be continued and gastric lavage is performed. Activated charcoal is not usually recommended due to the abnormally large volume needed to be effective. Bathing is repeated when there has been dermal exposure.
Supportive treatment: IV fluids are administered to maintain hydration and decrease the risk of kidney damage. The kidneys are monitored for several days to determine damage.
Specific treatment: Unavailable.
Prognosis
Variable

Toad Poisoning
Toxin
Toad and salamander venom
Source
All toads secrete mucus through the skin that does not taste good to other animals. Some toads, however, are actually poisonous. These include the tropical toads Bufo alvarius (Colorado River Toad) found in the Southwest desert and Bufo marinus found in Florida and Hawaii. Some other species of Bufotoads in other areas of the U.S. produce a milder venom. There is one species of poisonous salamander, the California Newt, which is found in California.
General Information
The toxin is produced by glands in the skin of these toads. The toxic agent is similar to the heart medication digoxin. Exposure is usually through oral exposure (the cat or dog mouthing the toad), but the toxin may also be absorbed through wounds or broken skin. There have been reports of toxicities from toads sitting in the pet's water dish.
Toxic Dose
Oral exposure to Bufo marinus can be fatal. The deadly effects can be seen within 15 minutes.
Signs
The venom is locally irritating causing head shaking, drooling, vocalizations, pawing at the mouth, retching, or vomiting. The mucus membranes may become red. In severe cases, heart rhythm disorders occur which may cause apparent blindness, seizures, collapse, and death.
Immediate Action
Very carefully wash mouth with large amounts of water such as from a slow moving stream of water from a hose. Seek veterinary attention.
Veterinary Care
General treatment: The animal's oral cavity and other exposed areas will be flushed with large amounts of water. Ideally, this is performed under anesthesia so the entire mouth and throat are rinsed. Activated charcoal may be administered.
Supportive treatment: The animal will be monitored with an EKG and treated for heart rhythm abnormalities with a drug such as propranolol. IV fluids will be administered to maintain hydration, and any seizures. Atropine may be given to help control the drooling if no heart abnormalities are present. Sedation may be necessary.
Specific treatment: Unavailable
Prognosis
Good, with treatment; exposure to Bufo marinus can be fatal.
