Why diarrhoea isn't the main concern after mineral spirit exposure
While some petroleum distillates can irritate the digestive tract, mineral spirits pose a more immediate threat to your cat's respiratory system. The liquid's low viscosity means it can be inhaled during grooming or if your cat shook its head after contact. This leads to chemical burns in the delicate lung tissue before stomach upset would typically develop.
Watch for wet coughing or a 'snorkeling' sound - these suggest fluid in the airways rather than just gastrointestinal irritation. The 5 kg body weight matters because smaller animals show neurological signs like wobbliness sooner, but respiratory damage appears first regardless of size.
The critical first hour after licking mineral spirits
Within 15-30 minutes, inhaled droplets begin attacking the alveoli where oxygen exchange happens. You might notice your cat holding its head low to let saliva drain, as swallowing becomes painful. Rapid panting that doesn't resolve when they calm down is an emergency.
Don't wait for vomiting or diarrhoea to appear - by then, lung damage is already progressing. The jar spill means your cat likely got more on its paws and face than just a casual lick, increasing aspiration risk during self-cleaning.
Why mineral spirits differ from other petroleum products
Unlike thicker oils or greases, mineral spirits evaporate quickly at room temperature, creating concentrated fumes near the spill. Your cat's licking motion likely drew these vapors into its nostrils simultaneously. This dual exposure - liquid contact plus inhaled fumes - accelerates lung injury.
The 'gas' you're noticing could actually be early respiratory distress rather than flatulence. Listen for short, shallow breaths between 40-60 per minute (normal is 20-30) and any blue-tinged gums.
What to do right now for a 5 kg cat
Immediately move your cat to fresh air without stressing it - sudden movement increases inhalation risk. Wipe its face and paws with a damp cloth to remove residue, but don't induce vomiting or give food/water. Even tiny amounts in the lungs expand over time.
Time matters more than the apparent lick quantity - symptoms often worsen 6-12 hours later as lung inflammation peaks. Your cat needs veterinary oxygen support before breathing becomes visibly labored.
