Bleach, cleaning products, essential oils (tea tree, eucalyptus, peppermint), antifreeze, and rodenticides are highly toxic. Use Cat-safe cleaning products throughout your home.
Toxic Foods
Onions, garlic, grapes, raisins, xylitol, alcohol, and caffeine are all toxic to Cats.
Dog Flea and Tick Products
Permethrin-based topical flea and tick treatments designed for dogs are acutely toxic to Cats. Never apply a dog flea or tick product to a Cat or allow a Cat near a recently treated dog.
Cannabis & Medicinal Mushrooms
Cannabis ingestion causes neurological signs, disorientation, and can be life-threatening depending on the amount and form. Certain medicinal mushrooms and supplements can also be toxic. When in doubt, call poison control immediately.
