Intoxication in pets means poisoning — exposure to a substance that causes harmful effects through its chemical action on the body. Common sources include household foods (chocolate, xylitol, grapes), medications (paracetamol, ibuprofen), plants (lilies in cats, sago palm), garden products (slug bait, rodenticides), and some cleaning chemicals.
Pets, particularly dogs, are indiscriminate eaters and are far more exposed to toxic substances than most owners realise. The same dose of a substance that causes mild symptoms in a 70kg human may be lethal to a 5kg dog. Cats face additional risk from their grooming behaviour — they absorb topically applied or contacted substances through their skin and coat during grooming, and their liver lacks certain detoxification enzymes present in dogs and humans.
Time is critical with intoxication. Some toxins (like xylitol or certain rodenticides) cause damage in a delayed fashion — the pet appears fine for hours before collapsing. Others (like lilies in cats, where even small amounts of pollen cause acute kidney failure) cause rapid deterioration. Never wait for symptoms to progress before calling for help. The ASPCA Animal Poison Control Center (888-426-4435) operates 24 hours a day.
Do not induce vomiting without veterinary guidance. Some substances cause more damage on the way back up (caustic chemicals, for example), and others have contraindications to vomiting induction. If you can, note the product name, estimated amount consumed, and time of ingestion before calling your vet or poison control — this information significantly affects treatment decisions.

Frequently Asked Questions about Intoxication (Pet Poisoning)
Q: My dog ate a small amount of chocolate — do I need to call the vet?
It depends on the type of chocolate, the amount, and your dog's weight. Dark chocolate and baking chocolate are far more toxic than milk chocolate. Use an online chocolate toxicity calculator (many are available from veterinary sources) to assess risk, and call your vet if there is any doubt. When in doubt, call.
Q: Are lilies really that dangerous for cats?
Yes — all parts of true lilies (Lilium and Hemerocallis species) are acutely nephrotoxic (kidney-destroying) to cats. Even ingesting a small amount of pollen, drinking water from a vase containing lilies, or licking the petals can cause fatal kidney failure within 36–72 hours without treatment. If any lily contact is suspected, it is a genuine emergency.
Q: What is xylitol and why is it dangerous for dogs?
Xylitol is a sugar alcohol used as a sweetener in sugar-free products: chewing gum, some peanut butters, baked goods, mouthwash, and medications. In dogs it causes a dangerous insulin surge (severe hypoglycaemia) and liver failure at higher doses. It is not toxic to cats to the same extent. Always check peanut butter and supplements for xylitol before giving to dogs.
