Common Household Hazards for Cats
In this guide
Cats are curious, agile, and fond of chewing and batting things, which brings them into contact with hazards dogs often miss. Many of the most dangerous are ordinary household items.
Knowing the main risks lets you cat-proof your home in an afternoon.
Lilies are especially dangerous
True lilies (Lilium) and day lilies (Hemerocallis) can cause severe kidney failure in cats. All parts are toxic, including pollen and the water in the vase — a cat can be poisoned simply by grooming pollen off its fur. The safest approach is not to bring lilies into a home with a cat at all. If you suspect exposure, contact a vet immediately.
Other toxic substances
- Permethrin — found in some dog flea treatments; never use dog products on cats
- Paracetamol (acetaminophen) and ibuprofen
- Antifreeze (ethylene glycol), which tastes sweet
- Essential oils and some liquid potpourri
- Onion, garlic, and chocolate
String, ribbons, and small objects
Cats often swallow string, thread, hair ties, and tinsel during play. These “linear foreign bodies” can bunch up the intestines and need surgery. If you see string hanging from your cat’s mouth or bottom, do not pull it — call your vet.
Windows and balconies
Cats can fall from open windows and balconies while chasing birds or insects. Fit secure screens or restrict access, especially in flats above the ground floor.
Appliances and small spaces
Check the washing machine and tumble dryer before every use — warm, enclosed spaces attract cats. Keep toilet lids down for kittens, and close drawers and cupboards where a cat could get trapped.
