Common Things That Are Poisonous to Cats and Kittens

Cats are curious by nature. Kittens? Even more so. They’ll sniff, lick, or chew on just about anything they find, whether it’s a tasty treat or a shiny new plant you just brought home. But unfortunately, some everyday items that seem harmless to us can be dangerous, even deadly, for cats.

Whether you’re a new kitten parent or a seasoned cat lover, it’s important to know what to keep out of reach. Here’s a breakdown of the most common poisons and toxins that can put your feline friend at risk.

Household Plants That Are Toxic to Cats

Many common houseplants are beautiful to look at but harmful if chewed on by your cat. Some of the most toxic include:

• Lilies – Even small amounts (pollen, leaves, or water from the vase) can cause kidney failure in cats.
• Pothos (Devil’s Ivy) – Causes mouth irritation, drooling, and vomiting.
• Dieffenbachia (Dumb Cane) – Can cause intense burning in the mouth, swelling, and difficulty swallowing.
• Sago Palm – Extremely toxic. Just one seed can cause liver failure.
• Aloe Vera – Good for sunburns, bad for cats. Can lead to vomiting and diarrhea.

If you’re not sure whether a plant is safe, it’s better to err on the side of caution and keep it out of your cat’s reach.

Human Foods Cats Should Never Eat

Some human foods can upset your cat’s stomach. Others can do serious damage. Avoid feeding your cat or kitten anything that includes:

• Onions and garlic – Even in powdered form, they can damage red blood cells and cause anemia.
• Chocolate – Contains theobromine, which is toxic to cats.
• Grapes and raisins – Can lead to kidney failure, even in small amounts.
• Caffeine – Found in coffee, tea, and energy drinks. It affects the heart and nervous system.
• Alcohol – Even tiny sips can lead to severe health problems or death.
• Xylitol – A sweetener found in toothpaste, sugar-free gum and baked goods. It’s extremely toxic to pets and can cause liver failure.

Keep all snacks, drinks, and leftovers well out of reach, especially if you have a counter-surfer in the house.

Common Household Products That Are Poisonous

Cats often walk through or lick things we wouldn’t think twice about. These everyday items are especially risky:

• Cleaning products – Bleach, ammonia, disinfectants, and toilet bowl cleaners can all be harmful if licked or inhaled.
• Rodent poisons – Deadly if ingested directly or if your cat catches a poisoned rodent.
• Antifreeze (ethylene glycol) – Just a few drops can be fatal. Keep garage items sealed and stored.
• Essential oils – Tea tree, eucalyptus, citrus, and peppermint oils can cause vomiting, tremors, or liver damage in cats.

Always clean up spills immediately and store products in cabinets your cat can’t access. And be cautious with diffusers. Even essential oil vapors can cause problems.

Medications That Are Dangerous to Cats

Never give your cat human medicine unless directed by a vet. Even small doses can be harmful.

• Tylenol (acetaminophen) – Extremely toxic and can cause liver failure.
• Ibuprofen and aspirin – Can lead to ulcers, kidney failure, or worse.
• Antidepressants, ADHD meds, and sleep aids – All can cause serious neurological or cardiovascular symptoms.

Even veterinary medications prescribed for other animals (like dogs) can be unsafe for cats due to differences in metabolism. Always check with your vet first.

Well, why would you put all this tasty stuff here if you didn’t want me to eat it? I really don’t understand my humans sometimes. #KittyBuffet #GreenStuffIsYummy #SneakySnacksAreMyWeakness #NeverTooFullToTrySomethingNew

Symptoms can vary based on what was ingested, but common signs of poisoning include:

• Vomiting or diarrhea
• Excessive drooling
• Lethargy or weakness
• Tremors or seizures
• Pale gums

• Loss of appetite
• Unusual behavior or vocalization

If your cat is showing any of these symptoms and you suspect poisoning, call your veterinarian or an emergency pet poison hotline immediately.

Final Thoughts: A Safe Home Is a Cat-Friendly Home

Kittens are explorers. Cats are climbers, chewers, and snoops. Keeping harmful items out of reach is one of the simplest ways to keep your feline family members safe.

Take a quick inventory of your home and look for anything on this list. It might mean storing some cleaning products in locked cabinets or swapping out a plant or two, but your cat will thank you with a longer, healthier life.

A little prevention goes a long way when you’ve got a curious kitty in the house.
