Search foods, plants, essential oils, medications, and household products to see whether they are generally safe, cautionary, toxic, or urgent for cats.
Use this cat safety database to quickly check common items like lavender, lilies, peppermint oil, onion, garlic, tuna, aloe vera, household cleaners, human medications, and more.
Every item is organized by type so you can quickly compare foods, plants, essential oils, medications, and household products.
Cats are obligate carnivores, but many human foods still appear in cat safety searches. Some foods are harmless in tiny amounts, while others can cause serious poisoning.
Examples: onion, garlic, tuna, milk, rice, pumpkin, peanut butter, chocolate
Plant safety is one of the highest-risk cat categories. Some plants cause mild stomach upset, while others, especially lilies, can be life-threatening even after small exposure.
Examples: lilies, aloe vera, lavender, eucalyptus, pothos, tulips, sago palm
Cats are uniquely sensitive to many essential oils because they have limited ability to metabolize certain aromatic compounds. Ingestion, skin contact, grooming, and diffuser exposure can all matter.
Examples: tea tree oil, peppermint oil, eucalyptus oil, lavender oil, citrus oil, cinnamon oil
Human medications can be dangerous for cats, even in small amounts. Never give pain relievers, allergy medicine, sleep aids, stomach medication, or topical products without veterinary guidance.
Examples: Tylenol, ibuprofen, Benadryl, Neosporin, melatonin, gabapentin
Cleaners, disinfectants, pest-control products, soaps, fragrances, and lawn chemicals may be risky through licking, paw contact, inhalation, or grooming after residue gets on the fur.
Examples: Pine-Sol, Fabuloso, Dawn dish soap, Raid, boric acid, hydrogen peroxide, Febreze

These items are known to be dangerous for cats and should be avoided.
These items may be safe in some situations but risky depending on amount, form, concentration, ingredients, cat size, age, or health condition.
These items are commonly tolerated by many healthy cats when plain, prepared safely, and offered in appropriate amounts. Individual cats may still react differently.
These are common items cat owners look up when they need a fast answer.
Lavender oil is risky for cats, while plant exposure depends on amount and form.
True lilies can cause life-threatening kidney failure in cats, even after small exposure.
Cats have difficulty metabolizing compounds in peppermint oil, and diffuser exposure may also be risky.
Eucalyptus contains compounds cats may not process well and can cause drooling, vomiting, weakness, or neurological signs.
Tea tree oil is one of the highest-risk oils for cats, especially with skin contact or ingestion.
Onions can damage red blood cells and may cause delayed anemia.
Garlic is more concentrated than onion and may be dangerous even in small amounts.
Plain tuna may be tolerated occasionally, but it is not a balanced daily food and can contain excess salt or mercury.
Aloe can cause vomiting, diarrhea, lethargy, and stomach upset in cats.
Many adult cats are lactose intolerant, so milk can cause diarrhea or digestive upset.
If your cat may have eaten, licked, inhaled, or touched something toxic, act quickly. Cats often hide illness, and some toxins can cause delayed symptoms.
Move your cat away from the plant, oil, food, medication, cleaner, diffuser, pesticide, or product.
If oil, cleaner, pesticide, or residue is on the fur or paws, stop your cat from licking it and contact a veterinarian for safe cleaning instructions.
Look for the item name, ingredients, concentration, strength, amount missing, and packaging details.
Note when the exposure happened, how much may have been eaten or touched, and whether your cat inhaled fumes or diffuser mist.
Common warning signs include vomiting, drooling, diarrhea, tremors, weakness, breathing trouble, loss of appetite, hiding, collapse, seizures, or unusual behavior.
Do this immediately for lilies, essential oils, onions, garlic, human medications, pesticides, concentrated cleaners, unknown amounts, or any symptoms.
Do not induce vomiting, give home remedies, bathe aggressively, or apply oils unless a veterinarian or poison-control professional tells you to.
Cats are not small dogs. Their bodies handle many substances differently, which is why a product that seems harmless for humans or dogs may still be risky for cats.
Cats have limited ability to process certain compounds found in some medications, plants, and essential oils. This can make small exposures more serious than expected.
Cats groom frequently. A substance on the fur or paws can become an ingestion exposure when the cat licks it off.
Because cats are small, a small amount of a toxic substance can represent a larger dose relative to body weight.
Diffusers, sprays, residues, treated surfaces, plants, and topical products can expose cats even when they do not directly eat the item.
Some toxins may not cause obvious signs immediately. Waiting until severe symptoms appear can make treatment harder.
Each safety guide uses a practical rating system to help you understand risk quickly. Ratings are educational and do not replace veterinary advice.
The item is commonly considered safe for many healthy cats in normal, appropriate amounts. Preparation still matters. Plain, unsalted, unseasoned, and small portions are usually safest.
Risk depends on amount, form, ingredients, cat size, age, health condition, or exposure type. Caution items may be tolerated by some cats but should not be treated as automatically safe.
The item can harm cats and should be avoided. Known ingestion, repeated exposure, concentrated forms, skin contact, or symptoms may require veterinary guidance.
Known or suspected exposure may require urgent help, especially if the amount is unknown, the item is highly toxic, skin or ingestion exposure occurred, or symptoms are present.
The same substance can carry different risks depending on how your cat was exposed.
Eating, licking, or chewing an item is often the highest-risk exposure. Amount, concentration, and body weight matter.
Some oils, cleaners, pesticides, and topical products can irritate skin and may be swallowed later during grooming.
Diffusers, sprays, fumes, smoke, and airborne chemicals can irritate the lungs. Cats with asthma, kittens, senior cats, and cats in enclosed rooms may be at higher risk.
Residue on fur or paws can become an ingestion exposure when a cat grooms.
Oils, powders, extracts, supplements, and medications may be far stronger than the original plant or food.
Foods and products may contain dangerous ingredients such as onion, garlic, xylitol, alcohol, caffeine, phenols, pesticides, or disinfectants.
New substances are added regularly as we expand the cat safety database.

Guide plannedCat safety guidance is based on veterinary toxicology references, poison-control guidance, and reputable veterinary sources. When a substance has known toxicity, we prioritize cautious wording and action-focused guidance over casual reassurance.
Because individual risk depends on your cat's size, age, health, amount exposed, product form, and exposure route, always contact a licensed veterinarian for case-specific advice.
