Top 10 Common Household Toxins for Cats & Dogs in BC

Keeping our pets safe is one of the most important responsibilities we have as pet owners. Cats and dogs are naturally curious, and while that curiosity is endearing, it often leads them into potentially dangerous situations. In homes across North Vancouver and West Vancouver, common household items—foods, plants, medications, and chemicals—can pose serious health risks.

At North Care Animal Hospital, our team has treated countless cases of accidental poisonings. Many of these emergencies could have been prevented with awareness and proactive pet-proofing. In this article, we’ll highlight the top 10 household toxins for pets in British Columbia, the signs of toxicity, and what steps you should take if your pet is exposed.


Why Awareness of Toxins Matters

Pet poisonings can escalate quickly. For example, ingesting even a small amount of xylitol (a sugar substitute) can cause hypoglycemia and liver failure in dogs. Cats are even more sensitive; certain plants like lilies can cause acute kidney failure with just a nibble of a leaf.

Having access to urgent veterinary services is critical. Our hospital offers Pet Emergency Services in North Vancouver with fast, reliable urgent care, available 7 days a week, from 8:00 AM – 10:00 PM.


Top 10 Household Toxins for Cats & Dogs

1. Chocolate and Caffeine

  • Contain theobromine and caffeine, which cause hyperactivity, tremors, seizures, and potentially death.

  • Dark chocolate and cocoa powder have the highest toxicity.

  • Dogs are more likely to ingest chocolate, but cats are also at risk.

2. Xylitol (Sugar Substitute)

  • Found in gum, candy, peanut butter, and baked goods.

  • Causes rapid insulin release → hypoglycemia (low blood sugar).

  • In dogs, ingestion can lead to seizures and liver failure.

3. Grapes and Raisins

  • Even small amounts can cause acute kidney failure in dogs.

  • The exact toxin is unknown, but ingestion can result in vomiting, lethargy, and decreased urination.

4. Onions, Garlic, and Chives

  • Members of the allium family.

  • Cause hemolytic anemia by damaging red blood cells.

  • Cats are highly sensitive, but dogs are also at risk.

5. Medications (Human & Veterinary Overdose)

  • Pain relievers like ibuprofen, acetaminophen, and naproxen are highly toxic.

  • Cats are especially sensitive to acetaminophen, leading to methemoglobinemia (low oxygen in blood).

  • Always secure your prescriptions and over-the-counter meds.

6. Rodenticides (Rat & Mouse Poison)

  • Active ingredients include anticoagulants (warfarin, bromadiolone), neurotoxins, and vitamin D analogs.

  • Clinical signs: bleeding, seizures, or kidney damage depending on the formulation.

  • Pets can also be poisoned by eating rodents that consumed the bait (secondary poisoning).

7. Antifreeze (Ethylene Glycol)

  • Extremely palatable due to its sweet taste.

  • Causes calcium oxalate crystal formation, leading to acute kidney failure.

  • Just a teaspoon can be fatal for cats.

8. Household Cleaners & Disinfectants

  • Bleach, ammonia, and quaternary ammonium compounds cause chemical burns.

  • Symptoms: drooling, vomiting, difficulty breathing.

  • Always store cleaners out of reach and rinse pet bowls thoroughly.

9. Toxic Plants (Indoor & Outdoor)

  • Lilies (toxic to cats), azaleas, sago palms, tulips, and daffodils can all be lethal.

  • Outdoor gardens in Vancouver often contain rhododendrons, which are highly toxic.

10. Alcohol & Recreational Substances

  • Alcohol, marijuana edibles, and other recreational drugs can cause CNS depression, coma, or death.

  • With legalization, marijuana toxicity in pets has become one of the most common ER visits in Vancouver clinics.

What to Do if Your Pet is Exposed

  1. Do not induce vomiting without professional advice. Some toxins cause more harm coming back up.

  2. Call a veterinarian immediately. Timing is critical; some toxins can be counteracted with antidotes if treated early.

  3. Bring the packaging or sample of what your pet ingested to the clinic.

We provide urgent support through our Walk-In Vet Services in North & West Vancouver. If you cannot bring your pet in immediately, we also offer In-Home Veterinary Services across North & West Vancouver.
