Food, plants, and chemicals that commonly cause pet poisoning
Cats and dogs can be ingenious at helping themselves to things we don’t want them to have. And unfortunately, a lot of delicious human foods, cool decorations, and useful chemicals may hurt, or even kill, your unsuspecting pet. Help the pet you love stay safe. Be aware of the risks, and do your best to keep dangerous items out of reach.
This is not a complete list of potential toxins or health risks. If you have any concerns or questions, please reach out to your veterinary team.

What’s poisonous for cats?
In addition to the list above, cats are especially vulnerable to certain poisons. Keep an eye on your kittyBAE and act immediately if you suspect your cat has sampled any of the below.
- Acetaminophen (Tylenol)
- Antifreeze
- Bleach or other wet or sticky chemicals
- Dog (or rabbit) parasite control that contains permethrin
- Lilies of any type

What’s poisonous for dogs?
Dogs can be champions at trying things that aren’t good for them. As well as the list above, here are a few things that are especially toxic for your doggyBFF — if you think they’ve been poisoned, act now.
- Avocado skin, pits, and leaves
- Blue cheese
- Hops (used in home brewing)
- Kitchen spices (like nutmeg), herbs, and baking soda
- Macadamia nuts, even in small amounts
- Moldy or spoiled food
- Pits from fruits like peaches and plums
Why are these foods and substances toxic to pets?
There are many, many reasons why your pet may get sick from something you personally eat or use all the time. Often, it’s simply because pet bodies aren’t designed like people bodies, and they just can’t process the same materials in the same way.
Animals can easily overdose on people medication, or get very sick from small amounts of alcohol or caffeine. Plus, even the smartest pet may not think the same way people do, or have the same information — like knowing that the sweet-smelling lily on your side table isn’t good to eat.
As a loving pet owner, you can help your pet avoid toxins and other hazards by being informed. We’re here to help. If you have any questions or concerns about what your pet should eat or what’s safe to have in your home, please reach out to your veterinary team.

In an emergency, please contact your local veterinary emergency hospital.
