Cats’ curious nature can sometimes lead them into dangerous situations. In 2010, nearly 9% of calls to the Pet Poison Helpline were feline-related, with exposures ranging from human medications to toxic plants.1
As a responsible cat owner, being aware of the potential hazards lurking in your home is crucial. From seemingly harmless items to common household products, many everyday objects can pose serious risks to your feline friend.
Here are 15 of the most dangerous household items for cats.
1. Lilies & Other Toxic Plants
Lilies are extremely poisonous to cats, causing acute kidney failure even in small amounts. Other common houseplants like azaleas, tulips, and sago palms can also be toxic if ingested.
Many cat owners are unaware of the dangers posed by certain plants. Familiarize yourself with the ASPCA’s list of toxic and non-toxic plants to ensure your home is free of hazardous greenery.
2. Human Medications
Common over-the-counter and prescription medications can be lethal to cats. Painkillers like ibuprofen and acetaminophen, antidepressants, and ADHD drugs are particularly dangerous.
Never give your cat human medications without consulting your veterinarian first. Keep all medicines securely stored in a cabinet or drawer that your cat cannot access.
3. Household Cleaners
Many cleaning products contain harsh chemicals that can cause burns, respiratory issues, or poisoning in cats. These include bleach, laundry detergent, drain cleaners, toilet bowl cleaners, and certain types of floor cleaners.
Always read labels carefully and opt for pet-safe, natural cleaning products when possible. Store cleaners in a secure location and keep your cat away from recently cleaned areas until surfaces are dry.
4. String, Yarn, & Thread
While cats love playing with string-like objects, they can easily swallow them, leading to intestinal obstructions that may require surgery. This includes yarn, thread, dental floss, rubber bands, and hair ties.
Offer your cat safe, store-bought toys instead of string or yarn. If you enjoy crafting, be sure to keep your supplies securely stored when not in use.
5. Essential Oils
Essential oils are rapidly absorbed through the skin and can be toxic to cats if ingested or inhaled. Peppermint, clove, eucalyptus, and tea tree oils are some of the most dangerous.
If you use essential oils in your home, keep them out of reach and avoid diffusing them around your cat. Opt for pet-safe, natural air fresheners instead.
6. Chocolate & Caffeine
Chocolate contains theobromine and caffeine, both of which are toxic to cats. Ingesting even small amounts can cause vomiting, diarrhea, seizures, and heart problems.
Keep all chocolate and caffeinated products, including coffee, tea, and energy drinks, away from your cat. If you suspect your cat has ingested chocolate or caffeine, contact your veterinarian immediately.
7. Grapes & Raisins
Grapes and raisins can cause acute kidney failure in cats. The exact toxic substance is unknown, but even small amounts can be dangerous.
Avoid giving your cat any foods containing grapes or raisins, and keep them securely stored in a refrigerator or pantry that your cat cannot access.
8. Batteries
If chewed or punctured, batteries can leak harmful chemicals that cause burns in the mouth, esophagus, or stomach. Button batteries are especially dangerous as they can be easily swallowed.
Keep spare batteries out of reach, and avoid leaving them in open containers or on countertops. If you suspect your cat has ingested a battery, seek veterinary care immediately.
9. Xylitol
Xylitol is an artificial sweetener found in many sugar-free products like gum, candy, and toothpaste. It can cause a rapid drop in blood sugar and liver failure in cats.
Read labels carefully and avoid bringing xylitol-containing products into your home. If you do, store them in a secure cabinet that your cat cannot access.
10. Mothballs
Mothballs contain toxic chemicals that can cause serious health issues in cats, including anemia, liver damage, and neurological problems.
Use cedar chips or other pet-safe moth deterrents instead of mothballs. If you must use them, keep them in sealed containers and store them in an area your cat cannot reach.
11. Antifreeze
This is a well known, but still worth the reminder. Antifreeze contains ethylene glycol, which has a sweet taste that attracts cats. Ingesting even small amounts can cause acute kidney failure and death.
Clean up any antifreeze spills immediately and store it in a secure location. Consider using pet-safe antifreeze products that contain propylene glycol instead.
12. Onions & Garlic
Onions, garlic, and other members of the allium family can cause anemia in cats by damaging their red blood cells. This includes raw, cooked, and powdered forms.
Keep onions and garlic away from your cat, and avoid feeding them any foods seasoned with these ingredients. If you suspect your cat has ingested onions or garlic, monitor them closely and contact your veterinarian if they show signs of illness.
13. Plastic Bags
Cats may be attracted to the crinkly sound of plastic bags, but they can easily suffocate or choke on them. Ingesting small pieces of plastic can also cause intestinal blockages.
Store plastic bags out of reach and dispose of them properly. Consider using reusable, pet-safe storage containers instead.
14. Electrical Cords
Cats may be tempted to chew on electrical cords, which can lead to burns, shock, or electrocution. Kittens and young cats are especially curious and prone to cord-chewing.
Keep cords tidy and out of reach by using cord organizers or covers. Unplug appliances when not in use and provide your cat with plenty of safe, engaging toys to discourage chewing.
15. Tobacco Products
Tobacco contains nicotine, which is toxic to cats. Ingesting cigarettes, cigars, or chewing tobacco can cause vomiting, diarrhea, seizures, and even death.
Keep all tobacco products out of reach, and avoid smoking around your cat. Dispose of cigarette butts properly and wash your hands after smoking to avoid transferring nicotine to your cat’s fur.
By being aware of these common household hazards and taking steps to keep your cat safe, you can create a healthy, happy home for your feline friend. Remember, prevention is key – always err on the side of caution and consult your veterinarian if you have any concerns about your cat’s health or safety.
