Common Pet Toxins in Australia | Foods, Plants & Poisoning Risks

Pet poisoning remains one of the most frequent emergency call-outs we see as mobile vets in Australia and one of the most preventable.

In everyday homes and gardens, dogs and cats are exposed to foods, plants, medications and chemicals that are harmless to people but dangerous or fatal to pets. In our experience at Pawssum Mobile Vets, many owners are genuinely shocked to learn how little exposure it can take.

This guide explains the most common pet toxins in Australia, the warning signs to watch for, and what action to take if you’re worried your pet has been exposed.

Why Pet Poisoning Is So Common in Australia

Australian households present a unique risk profile for pets. Many common toxins are:

• Readily available (kitchens, gardens, sheds)
• Slow-acting, delaying symptoms
• Highly concentrated for a pet’s body size

Unlike humans, pets:

• Metabolise substances differently
• Groom themselves after contact exposure
• Explore with their mouths

Poisoning doesn’t always require eating something licking paws, chewing plants, or inhaling fumes can be enough.

Toxic Foods for Dogs and Cats

Human food is one of the most frequent causes of pet poisoning we attend, especially during holidays and family gatherings.

High-Risk Foods Seen in Australian Homes

• Chocolate & cocoa products – cause tremors, seizures and heart rhythm issues
• Grapes & raisins – can trigger sudden kidney failure
• Xylitol (sugar-free gum, sweets, baked goods) – rapid blood sugar drop and liver failure
• Onion, garlic & chives – damage red blood cells
• Alcohol & caffeine – nervous system and heart toxicity
• Macadamia nuts – weakness, vomiting and neurological signs

Even small quantities can be life-threatening, particularly for cats and small dogs.

Toxic Plants Common in Australian Homes & Gardens

Many popular Australian indoor and outdoor plants are highly toxic to pets.

Plants We Frequently See Causing Poisoning

• Lilies – extremely toxic to cats; pollen alone can cause kidney failure
• Sago Palm – severe liver damage in dogs
• Oleander – dangerous heart toxicity
• Peace Lily – mouth swelling and pain
• Aloe Vera – vomiting and diarrhoea
• Philodendron – oral and throat irritation

Cats are particularly vulnerable because they groom after brushing against leaves or pollen.

Garden Poisons: Snail Bait, Rat Bait & Chemicals

Garden products are among the deadliest pet toxins we encounter.

High-Risk Garden Chemicals

• Snail and slug bait
• Rat and mouse poisons
• Herbicides and pesticides

These products may cause:

• Internal bleeding
• Seizures
• Respiratory distress
• Sudden collapse

⚠️ Many modern baits are slow-acting, meaning symptoms may appear hours or days later often when damage is already severe.

Human Medications & Supplements

Never give pets medication unless it is explicitly prescribed by a veterinarian.

Medications Commonly Involved in Poisoning

• Paracetamol (Panadol) – fatal to cats
• Ibuprofen & other anti-inflammatories
• Antidepressants
• Vitamin D supplements
• Cold & flu medications

In our experience, accidental ingestion of a single tablet can be enough to cause critical illness.

Household Chemicals & Cleaning Products

Pets can be poisoned by ingesting, inhaling, or absorbing chemicals through the skin.

Common risks include:

• Bleach and disinfectants
• Antifreeze
• Detergents and pods
• Essential oils
• Drain and oven cleaners

A frequent scenario we see is pets walking through freshly cleaned floors, then licking their paws.

Signs of Poisoning in Dogs & Cats

Symptoms vary depending on the toxin, but warning signs include:

• Vomiting or diarrhoea
• Excessive drooling or foaming
• Tremors or seizures
• Sudden lethargy or collapse
• Difficulty breathing
• Pale or yellow gums
• Loss of coordination

⚠️ Some poisons cause delayed symptoms, so absence of signs does not mean safety.

What To Do If You Suspect Poisoning

If you think your pet may have been exposed to a toxin:

Act Immediately

1. Contact Animal Poisons Helpline Australia

How to Reduce the Risk of Pet Poisoning

Simple steps make a big difference.

Practical Prevention Tips

• Store medications and chemicals securely
• Avoid toxic plants in pet-accessible areas
• Clean spills immediately
• Use pet-safe garden products
• Never leave human food unattended
• Supervise pets outdoors
