The full contents of the "household toxins and hazards" column in the 12-column knowledge tree for cats. Where the original text could not obtain an authoritative figure, it leaves the field blank and states why; this site preserves that as-is and does not fill in numbers on its behalf. The disease column is published separately as vet/cat-common-diseases and is not repeated here.

Cats | Household Toxins and Hazards

This article is compiled from the cat chapter of the veterinary animal encyclopaedia. The same sign calls for different handling in different species, and copying what works for another species can do harm — first confirm which animal you are dealing with.

Substance	Why it is especially dangerous to cats	Presentation	What to do immediately
*Lilies (Lilium* and Hemerocallis spp., including pollen and vase water)**	Acute tubular necrosis specific to cats	Vomiting, drooling, dullness → renal failure within days	Seek care on contact, do not wait for signs; do not have lilies in a house with cats
Acetaminophen / paracetamol	Deficient glucuronidation (C-2)	Swelling of the face / paws, muddy-grey or brown mucous membranes, rapid breathing, liver injury	A very small amount can be lethal; seek care immediately
Human NSAIDs (ibuprofen / naproxen / aspirin, etc.)	Long half-life, renal and gastric toxicity	Vomiting (which may contain blood), not eating, renal failure	Seek care immediately; never give a cat any human painkiller on your own
Canine synthetic pyrethroid permethrin spot-ons	Cats cannot metabolise it	Tremors, seizures, abnormal body temperature, death	Seek care immediately; do nothing beyond rinsing, and keep the cat warm on the way
Essential oils and phenolic cleaners (tea tree, eucalyptus, citrus, pine, mint, wintergreen; cresol / phenolic floor cleaners)	Dermal absorption plus ingestion during grooming; passive exposure from diffusers	Drooling, weakness, hepatotoxicity, skin burns	Stop use and seek care; do not use diffusers or phenolic cleaners in a house with cats
Ethylene glycol antifreeze	Sweet-tasting, lethal renal failure at extremely low doses, with a very short golden window	Walking unsteadily as if drunk → vomiting → anuric renal failure	One of the most urgent of all; seek care immediately
Rodenticides (anticoagulant type / bromethalin / cholecalciferol)	Each type has a different mechanism and different handling	Bleeding / neurological signs / hypercalcaemic renal injury	Seek care immediately and take the packaging with you (the active ingredient determines the antidotal direction)
Slug bait (metaldehyde)	Strongly seizure-inducing	Tremors, seizures, hyperthermia	Seek care immediately
Allium species (onion, garlic, chives, spring onion, including powders and soups)	Oxidative haemolysis, Heinz bodies	Weakness, pale mucous membranes, dark urine	Seek care
Grapes and raisins	Clearly nephrotoxic in dogs; data in cats are limited but avoid entirely	Vomiting, renal injury	Seek care
Chocolate / caffeine / tea	Methylxanthines	Agitation, arrhythmia, seizures	Seek care
Xylitol	Clear in dogs, evidence in cats is limited but still avoid	—	Avoid contact
Alcohol, raw dough	Alcohol poisoning, gastric fermentation and distension	Weakness, abdominal distension	Seek care
Human topical medicines: 5-fluorouracil cream, oestrogen gel / patch, calcipotriol, corticosteroid-containing ointments	Poisoning from licking or rubbing against them; 5-FU is extremely lethal to cats	Vomiting, seizures, bone-marrow suppression	Seek care immediately; cover the skin after application and do not share a bed with the cat
Human psychiatric / cardiovascular / diabetes medications	Dropped on the floor, they get played with and swallowed	Varies by drug	Lock the pill box away; if ingested, seek care immediately and bring the pill box
Lead, zinc (coins, toys, plumbing fittings), button batteries	Heavy-metal poisoning / corrosive burns	Vomiting, anaemia, oral burns	Seek care immediately
Plants (other than lilies): sago palm, azalea, oleander, tulip and hyacinth bulbs, pothos / peace lily (oral irritation), ivy, monstera, cannabis and its products	Hepatotoxicity / cardiotoxicity / oral burns / neurological signs	Varies by species	Seek care and bring a photograph of the plant
String-like items: sewing thread, yarn, dental floss, hair ties, ribbon, Christmas tinsel, earphone cables	Linear foreign bodies saw through the intestine	Repeated vomiting, not eating	Do not pull; seek care immediately
Raw meat / raw fish	Salmonella, toxoplasma, thiaminase causing B1 deficiency	Gastroenteritis / neurological signs	Switch to a complete diet
Physical hazards	Unclosed washing machines and tumble dryers, drawers, balconies without screens, electrical cables, crush injuries from doors, high temperatures on glassed balconies, insecticide sprays and foggers, freshly mopped wet floors, fumes from dry-heated non-stick pans	—	Check them off one by one (see the safety row in column 3)

General rule for poisoning: ① do not induce vomiting yourself (emesis in cats must be performed by a veterinarian) ② do not give milk / oil / salt on your own ③ bring the packaging, the ingredient label, the plant itself or a photograph with you ④ note down the approximate time ⑤ the telephone numbers of 24-hour animal emergency and poison-advice lines in your area 【depends on locality, and this file does not supply specific numbers — this is region-specific information and belongs to the do-not-fill category】; ask your local animal hospital or animal poison advice centre and write it on the fridge in advance.
