Substances that are toxic to cats

Cats can be particularly sensitive to certain toxic substances, some of which might be harmless to humans. Here's a list of common toxic substances for cats according to the Cornell University College of Veterinary Medicine.

  • Human medications: Over-the-counter and prescription drugs, including pain relievers like aspirin, acetaminophen, and ibuprofen, can be highly toxic to cats.
  • Insecticides: Products designed for flea and tick removal, especially those intended for dogs, can be poisonous to cats.
  • Human foods: Cats should not consume grapes, onions, garlic, raisins, avocados, chocolate, or foods containing the sweetener xylitol.
  • Plants: Many houseplants and flowers, including lilies, tulips, foxglove and philodendron are toxic to cats and can cause kidney failure or other serious health issues.
  • Veterinary medications: Even medications intended for pets can be harmful if misused or if cats gain access to them.
  • Rodenticides: Rat and mouse poisons are hazardous and can cause internal bleeding or kidney damage if ingested by cats.
  • Household cleaners: Bleach, detergents, and disinfectants can be harmful if ingested or if they come into contact with a cat's skin.
  • Heavy metals: Lead, zinc, and mercury, found in objects like paint chips or pennies, can be toxic if ingested.
  • Garden products: Fertilizers and other garden chemicals can be poisonous if a cat ingests them.
  • Chemical hazards: Substances like antifreeze, paint thinner, and pool chemicals can cause severe health problems, including kidney failure and chemical burns.
