Why Mosquito Coils Are Dangerous for Cats
📝 Summary
Most mosquito repellents contain pyrethroids that a cat's liver cannot break down. Even small exposure can poison a cat, so physical and plant-based methods are far safer for cat homes.
1 Why Mosquito Coils Are Dangerous for Cats
Are common repellents toxic to cats?
Common ones: coil, plate, repellent mat, most contain pyrethroids.
They confuse mosquitoes’ nerves, killing or stunning them.
Safe for us, human liver metabolizes them to non or low-toxic; reasonable use is safe.
But, important things thrice:
Cats cannot metabolize pyrethroids!
Cats cannot metabolize pyrethroids!
Cats cannot metabolize pyrethroids!
Cats tolerate pyrethroids far less than humans; inhaled, they deposit in the liver, hard to metabolize, accumulating and causing internal injury.
Too much causes protein denaturation, nerve damage, organ failure, even death, mosquito coil is outright poison to cats!
Some may wonder:
We use coils and the cat seems fine. Usually symptoms don’t show immediately.
Like humans overdosing, cat poisoning by degree shows:
1. Lethargy, drooling
2. Unsteady walking, loss of balance
3. Over-excitement, later convulsions
4. Vomiting
5. Loss of appetite
Especially middle-aged and older cats may get liver disease. Besides pyrethroids, DEET and lemon eucalyptus oil are also common, avoid them too. Some ask why their cat is fine after years; poisoning is dose-based by weight.
Per kg of cat weight, 1 ml ingested shows symptoms; 40 to 80 ml per kg is fatal. A 4 kg cat, about 8 to 9 jin, shows toxicity at 4 ml licked.
Over 160 ml may kill. A 100 ml repellent bottle rarely fully drunk, but beware accidental ingestion.
How can cat homes repel mosquitoes safely?
1. Physical methods
For 100% safety, stop coils; install sturdy screens, not ordinary ones cats tear through.
Keep a mosquito swatter, kill mosquitoes and get exercise.
2. Plant methods
Safe plants: lemongrass, mint, jasmine, impatiens, repel mosquitoes; but some cats may destroy the flowers.
3. Isolation method
At dusk, use liquid repellent but leave the room 1 to 2 hours, ventilate, don’t use all night; keep the bottle away from cats to avoid spills, and watch for sneezing.
Finally, if ingested, take the product label and packaging to the vet immediately!
