Why fabric makes ingestion amounts unpredictable
Your 4 kg cat didn't just ingest kerosene—she chewed a fuel-soaked textile, which acts like a sponge. Older rags are especially risky because repeated exposure to air makes the fibers more brittle. Those broken threads can form a felt-like mass in her stomach, trapping kerosene against the lining for prolonged absorption.
Check her bedding—if you smell kerosene on where she sleeps, she's likely still grooming it off her paws and fur, creating ongoing exposure.
The double threat of fibers and fuel
Natural fibers like cotton or wool swell when wet, potentially causing an obstruction as they move through her narrow feline intestines. Synthetic rags are worse—they don't break down and may require surgical removal. Watch for hunched posture or reluctance to jump—early signs of abdominal pain in cats.
Don't be fooled by normal litter box habits—cats with partial blockages may pass small stools while the real danger builds upstream.
How age affects kerosene's impact on cats
An older rag doesn't make the kerosene itself more toxic, but your cat's smaller liver (proportionally) struggles more with processing hydrocarbons than a dog's would. At 4 kg, her enzyme systems can easily be overwhelmed—jaundice (yellow gums) would indicate liver stress but often appears too late.
Press gently behind her rib cage—if she flinches or drools, that's a sign of liver capsule stretching, requiring urgent bloodwork.
Why cats hide aspiration symptoms
Unlike dogs, cats rarely cough obviously when they've inhaled hydrocarbons. Instead, they develop rapid shallow breathing and may sit with elbows out to expand their chest. Watch for exaggerated belly movements or open-mouth breathing—cats normally never pant like dogs.
Count her resting breaths per minute—over 40 when completely calm means lung irritation is developing, even if she isn't coughing.
