Top Poisons That Can Harm Pets

WASHINGTON, DC (WUSA)--The American Society for the Prevention of Cruelty to Animals (ASPCA) has come out with a list of common items found around the house that can poision pets. On the face of it, some of these items may seem harmless; however, if eaten by a pet, they can kill.

The ASPCA says if your pet ingests any of these items, you should contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately. Please note there is a $60 consultation fee if you call the ASPCA number.

Human Medications

NSAIDs

NSAIDs (non-steroidal anti-inflammatory drugs) like ibuprofen or naproxen are the most common cause of pet poisoning in small animals, and can cause serious problems even in minimal doses. Pets are extremely sensitive to their effects, and may experience stomach and intestinal ulcers and-in the case of cats-kidney damage.

Antidepressants

Antidepressants can cause vomiting and lethargy and certain types can lead to serotonin syndrome-a condition marked by agitation, elevated body temperature, heart rate and blood pressure, disorientation, vocalization, tremors and seizures.

Acetaminophen

Cats are especially sensitive to acetaminophen, which can damage red blood cells and interfere with their ability to transport oxygen. In dogs, it can cause liver damage and, at higher doses, red blood cell damage.

Methylphenidate (for ADHD)

Medications used to treat ADHD (Attention Deficit Hyperactivity Disorder) in people act as stimulants in pets and can dangerously elevate heart rates, blood pressure and body temperature, as well as cause seizures.

Fluorouracil

Fluorouracil-an anti-cancer drug-is used topically to treat minor skin cancers and solar keratitis in humans. It has proven to be rapidly fatal to dogs, causing severe vomiting, seizures and cardiac arrest even in those who've chewed on discarded cotton swabs used to apply the medication.

Isoniazid

Often the first line of defense against tuberculosis, isoniazid is particularly toxic for dogs because they don't metabolize it as well as other species. It can cause a rapid onset of severe seizures that may ultimately result in death.

Pseudoephedrine

Pseudoephedrine is a popular decongestant in many cold and sinus products, and acts like a stimulant if accidentally ingested by pets. In cats and dogs, it causes elevated heart rates, blood pressure and body temperature as well as seizures.

Anti-diabetics

Many oral diabetes treatments-including glipizide and glyburide-can cause a major drop in blood sugar levels of affected pets. Clinical signs of ingestion include disorientation, lack of coordination and seizures.

Vitamin D derivatives

Even small exposures to Vitamin D analogues like calcipotriene and calcitriol can cause life-threatening spikes in blood calcium levels in pets. Clinical signs of exposure-including vomiting, loss of appetite, increased urination and thirst due to kidney failure-often don't occur for more than 24 hours after ingestion.

Baclofen

Baclofen is a muscle relaxant that can impair the central nervous systems of cats and dogs. Some symptoms of ingestion include significant depression, disorientation, vocalization, seizures and coma, which can lead to death.

People Foods To Avoid Feeding Pets

Chocolate, Coffee, Caffeine

These products all contain substances called methylxanthines, which are found in cacao seeds, the fruit of the plant used to make coffee and in the nuts of an extract used in some sodas. When ingested by pets, methylxanthines can cause vomiting and diarrhea, panting, excessive thirst and urination, hyperactivity, abnormal heart rhythm, tremors, seizures and even death. Note that darker chocolate is more dangerous than milk chocolate. White chocolate has the lowest level of methylxanthines, while baking chocolate contains the highest.

Alcohol

Alcoholic beverages and food products containing alcohol can cause vomiting, diarrhea, decreased coordination, central nervous system depression, difficulty breathing, tremors, abnormal blood acidity, coma and even death.

Avocado

The leaves, fruit, seeds and bark of avocados contain Persin, which can cause vomiting and diarrhea in dogs. Birds and rodents are especially sensitive to avocado poisoning, and can develop congestion, difficulty breathing and fluid accumulation around the heart. Some ingestions may even be fatal.

Macadamia Nuts

Macadamia nuts are commonly used in many cookies and candies. However, they can cause problems for your canine companion. These nuts have caused weakness, depression, vomiting, tremors and hyperthermia in dogs. Signs usually appear within 12 hours of ingestion and last approximately 12 to 48 hours.

Grapes & Raisins

Although the toxic substance within grapes and raisins is unknown, these fruits can cause kidney failure. In pets who already have certain health problems, signs may be more dramatic.

Yeast Dough

Yeast dough can rise and cause gas to accumulate in your pet's digestive system. This can be painful and can cause the stomach or intestines to rupture. Because the risk diminishes after the dough is cooked and the yeast has fully risen, pets can have small bits of bread as treats. However, these treats should not constitute more than 5 percent to 10 percent of your pet's daily caloric intake.

Raw/Undercooked Meat, Eggs and Bones

Raw meat and raw eggs can contain bacteria such as Salmonella and E. coli that can be harmful to pets. In addition, raw eggs contain an enzyme called avidin that decreases the absorption of biotin (a B vitamin), which can lead to skin and coat problems. Feeding your pet raw bones may seem like a natural and healthy option that might occur if your pet lived in the wild. However, this can be very dangerous for a domestic pet, who might choke on bones, or sustain a grave injury should the bone splinter and become lodged in or puncture your pet's digestive tract.

Xylitol

Xylitol is used as a sweetener in many products, including gum, candy, baked goods and toothpaste. It can cause insulin release in most species, which can lead to liver failure. The increase in insulin leads to hypoglycemia (lowered sugar levels). Initial signs of toxicosis include vomiting, lethargy and loss of coordination. Signs can progress to recumbancy and seizures. Elevated liver enzymes and liver failure can be seen within a few days.

Onions, Garlic, Chives

These vegetables and herbs can cause gastrointestinal irritation and could lead to red blood cell damage. Although cats are more susceptible, dogs are also at risk if a large enough amount is consumed. Toxicity is normally diagnosed through history, clinical signs and microscopic confirmation of Heinz bodies. An occasional low dose, such as what might be found in pet foods or treats, likely will not cause a problem, but we recommend that you do NOT give your pets large quantities of these foods.

Milk

Because pets do not possess significant amounts of lactase (the enzyme that breaks down lactose in milk), milk and other milk-based products cause them diarrhea or other digestive upset.

Plants

Varieties such as azalea, rhododendron, sago palm, lilies, kalanchoe and schefflera are often found in homes and can be harmful to pets. Lilies are especially toxic to cats, and can cause life-threatening kidney failure even in small amounts.

Chemical Hazards

According to the ASPCA, in 2008, the Animal Poison Control Center handled approximately 5,500 cases of pet exposure to chemical hazards. A category on the rise, chemical hazards-found in ethylene glycol antifreeze, paint thinner, drain cleaners and pool/spa chemicals-form a substantial danger to pets. Substances in this group can cause gastrointestinal upset, depression, respiratory difficulties and chemical burns.

Heavy Metals

Heavy metals such as lead, zinc and mercury, which accounted for more than 3,000 cases of pet poisonings in 2008. Lead is especially pernicious, and pets are exposed to it through many sources, including consumer products, paint chips, linoleum, and lead dust produced when surfaces in older homes are scraped or sanded.

Fertilizer

It may keep your grass green, but certain types of fertilizer can cause problems for outdoor cats and dogs. Last year, the ASPCA fielded more than 2,000 calls related to fertilizer exposure.
